3.0 Physical Description

Horizon Compact is an integrated Ethernet modem and microwave radio transceiver, housed in a ruggedweatherproof housing. It is provided with two weatherproof connectors, Port 1 and Port 2. Port 1, copper10/100/1000 Base-t, or optional optical interface, carries data and optional in-band management traffic.Port 2, copper 10/100/1000 Base-t, carries optional out-of-band management traffic only. When Port 2 isnot in use, a weatherproof protective cap is used to seal the port.

A BNC style connector, with protective cap, is provided for obtaining field strength readings during theantenna alignment process. The output voltage is linear, giving 1 mV per dB values e.g. -30 mV = -30 dB.It is also used for providing a radio muting signal in system redundancy applications.

A high power variant is available, which requires a sun shield to meet temperature specifications.

3.1 Ethernet and Power Cabling

Note: For more information on installation and cabling, refer to DragonWave Technical Note:HC-TN-001.4 Horizon Compact PonE.

Two options of copper interface cabling are supported along with an optical interface.

3.1.1 Copper Interface – Option 1

Two, weatherproof, RJ45 Ethernet connectors provide data and management connections to the unit overCAT5E cabling. Ethernet cables must be wired for a straight through connection (see Section 4.0).

One connector (GigE – Port 1) is for data traffic and optional in-band management. Power (-36 to -60 VDC) is provided by an optional isolated mains power adaptor and supplied to the Horizon Compact usingPower on Ethernet (PonE) techniques via a PonE Power Adapter, which incorporates both power andnetwork surge arrestor. CAT5E cable length is restricted to 90 metres.

The second connector (Port 2) is solely for an optional out-of-band management connection, using anoverlay network. If Port 2 is not being used (e.g. in-band management being used), ensure that thevacant connector is sealed by fitting a weatherproof cap.

3.1.2 Copper Interface – Option 2

A composite cable, comprising two CAT5E cables and a power feed cable, connects to Port 1 with a MILspecification, multi-pin, connector. Various lengths are available (maximum 100 m). One CAT5E cable(blue) provides the data and optional in-band management connection to the Horizon Compact. Thesecond CAT5E cable (grey) is for optional out-of-band management only. Both are terminated at the dataend with shielded RJ45 connectors. The power feed cable connects to an isolated power supply (-36 to -60 V DC). Suitable power and network surge arrestor must be used. Port 2 is not available in this option.

3.1.3 Optical Interface

A weatherproof, MIL specification, multi-pin, connector is provided for Port 2, which includes the powerfeed. Port 1 has a weatherproof optical fibre connector. Single mode and multimode fibre options areavailable. As with the copper variant, Port 1 supports data traffic and optional in-band management andPort 2 is for power input plus optional out-of-band management or single wire 1+1 redundancyapplications.

A composite power and Ethernet cable assembly is available, which is compatible with the Horizon Port 2connector, which feeds power and optional out-of-band management to the Horizon.

Where distances prevent the use of the composite cable due to power feed loss, a special “Y” feedadaptor cable is available that allows customer provided, heavier duty, wires to be spliced into the powerfeed connection. The power feed wires (see Table 3-2 for recommended gauge) are spliced into theadapter cable using weatherproof tap connectors. The power feed and Port 2 Ethernet cables (maximumlength 100 m) are fed through a DragonWave surge arrestor unit designed to protect power and networkcircuits from transients.

DO NOT coil excess Ethernet cable, but fold in a zig-zag fashion whilstobserving a minimum bend radius of 2 inches. The affect of lightning inducedcurrent surges in the tower or conductors adjacent to the Ethernet cable will beminimized when the Ethernet cable is folded in this way.

DragonWave Inc.10


Table 3-2 Port 2 Power Cable Wire Gauge

These values are true for all radio variants and based on a minimum voltage of 35 V DC at the Horizon.

Distance from Power Supply to Horizon Unit 50 m 100 m 200 m 300 m

Minimum wire gauge required (AWG) 20 16 14 12

Note that the power wires in the composite cable are comprised of two pairs of 20 AWG wire, whichsupports the maximum length (100 m) when out-of-band management is employed using the combinedCAT5 cable.

3.2 Lightning ProtectionNote: For effective protection against lightning-induced surges, proper grounding and shieldingpractices MUST be followed for the ENTIRE installation. Consult DragonWave Inc. Technical Note:HC-TN-001.4 Horizon Compact PonE and Quick Reference Guide before installation!

The Horizon Compact is protected from cable transients and power surges caused by lightning, or othersources, by means of internal surge arrestor components and external housing grounding points (SeeSection 8.0).

For the Horizon Compact, copper interface variant, protection of the connected network and power supplyis provided by a proprietary DragonWave PonE power integrator/surge arrestor unit, into which theEthernet cables and power feed are connected. There are two variants of the copper powerintegrator/surge arrestor unit.

• Copper interface, outdoor use (see Figure 3-3)

o may be mounted on the outside wall of the network equipment building

• Copper interface, indoor use, wall or rack mountable (see Figure 3-4)

o must be mounted inside the network equipment building

Figure 3-3 Outdoor Power Integrator/SurgeArrestor

Figure 3-4 Indoor Power Integrator/SurgeArrestor

For the Horizon Compact, optical interface variant, or where PonE is not used to power the Horizon,protection of the power feed and the Ethernet connections is provided by a surge arrestor unit of similarphysical design to those described above. For correct installation procedures see Section 4.0.



3.3 Dual Polarization Radio Mount (DPRM)

The DPRM system allows two Horizon Compact units to be assembled to a single antenna. The antennaused is no different to that used for a single unit. One Horizon Compact unit is mounted for horizontalpolarization and the other for vertical polarization. Both units can transmit and receive simultaneously.This allows a link to carry up to 800 Mbps of Ethernet traffic. Although both units can operate on the samefrequency channels, with 30 dB isolation, it is recommended that different frequency channels be used foreach unit.

Figure 3-5 Dual Polarization Radio Mount

3.4 Power Switch Radio Mount (PSRM)

For redundancy purposes, the PSRM allows two Horizon units to be mounted to a single antenna. Bothunits must be oriented for the same polarization and only one unit can transmit/receive at any one time.The PSRM looks similar to the DPRM shown in Figure 3-5, but has internal components that only allowone unit to transmit/receive at a time.

Note that redundant systems do not have to use the PSRM. Each may be separately mounted to theirown antennas if desired. See Section 11.12 for more details.

The benefits of the PSRM are that only one antenna is required, reducing tower real estate requirements,reducing weight and minimizing wind loading.

Disadvantages include a 4 dB loss in signal when operating on the primary systems at each end of thelink and an 8.5 dB loss in signal when a secondary radio is activated (one end running on Primary andother end operating on secondary).

4.1 Surge Arrestor Units

The importance of protecting network and power systems from damaging voltage transients, induced bylightning and other sources, cannot be over emphasized.

DragonWave supplies four types of Surge Arrestor Units.

• Outdoor rated surge arrestor with integrated power on Ethernet (PonE)

• Indoor rated surge arrestor with integrated power on Ethernet (PonE)

• Outdoor rated surge arrestor only

• Indoor rated surge arrestor only

All four provide protection for up to two Ethernet network cables plus redundant power feeds.

4.1.1 Outdoor Surge Arrestor Units

The Outdoor units are housed in a weatherproof plastic enclosure employing gland nut seals for cableentry. Access to network and power terminals is via a gasket sealed lid, which is secured by four retainingscrews. Figure 4-1 shows the surge arrestor unit with integrated PonE, with lid removed.

Figure 4-1 Outdoor Surge Arrestor Unit with Integrated PonE Supply Feed

4.1.2 Indoor Surge Arrestor Units

The Indoor units are housed in a metal enclosure with an integral grounding lug and with direct access tonetwork and power connection terminations.

Figure 4-2 Indoor Surge Arrestor Unit with Integrated PonE Supply Feed

DragonWave Inc.16


Mounting systems for the indoor units include a 19” rack mounting adapter, which accommodates up totwo units within a 1U rack space, and wall mount brackets, allowing a single unit to be wall, or shelf,mounted as required (screw slots will accommodate 6mm (1/4”) diameter screws on 7.2” centres,horizontally).

4.3 Ethernet Cabling – Copper Interface – Option 1

For the copper interface, Option 1 (see Section 3.1.1), data cabling from the Horizon unit to the PonEPower Integrator/ surge arrestor consists of outdoor rated, shielded, CAT5E cables equivalent to Belden7919A. The shielded cables require shielded RJ45 connectors. Use of standard indoor unshielded RJ45connectors may result in a lack of lightning protection, poorly constructed cables, intermittent connectionsand data loss. Depending on the system configuration ordered and fielded, up to four shielded RJ45 andtwo unshielded RJ45 connectors are provided.

The cables terminate in a Horizon Power on Ethernet (PonE) power integrator/surge arrestor unit locatedeither outside of the building entry point (using the outdoor PonE unit) or inside the network equipmentbuilding (using the indoor PonE unit).

DO NOT CONNECT SHIELDED RJ45 CONNECTORS TO CABLES CONNECTING THE SURGEARRESTOR TO THE NETWORK SWITCH.

Note: Straight through Ethernet cables must be used between the PonE power integrator and theHorizon. The use of a cross-over type, or incorrectly wired CAT5E cables, will cause the PonEpower integrator to go into an alarm condition and not power up the Horizon Compact. A StatusLED indicates the status of the PonE power integrator (see Section 5.1.4)

The PonE unit contains surge arrestors and must be grounded according to local or regional ElectricalCodes. Unshielded Ethernet cables are connected between the PonE unit and the Ethernet switch orrouter. Power for the PonE unit is supplied by 2-wire 16 AWG electrical wiring, carrying 48 vDC (-48 v or+48v) with a maximum current draw of 2 amperes.

If Port 2 is not being used, ensure that a protective weatherproof cap is fitted to the port receptacle.

4.3.1 Using Outdoor PonE Unit

Figure 4-7 Outdoor Unit PonE and RJ45 Connections for Horizon




HolePlugs

4.3.2 Outdoor PonE Unit Weatherproof Grommet Seals

The cable entry points into the outdoor PonE unit are protected from moisture ingress by special rubbergrommet seals. Each grommet has three holes to accommodate up to three cables (two CAT5 and onepower). Rubber plugs are provided for holes that are not being used. Two holes, for CAT5, have a splitside to allow pre-terminated cables to be easily inserted. The third hole, which is smaller, is not split butallows un-terminated power cables to be pushed through. A gland nut is used to secure the cables andcreate the seal. Ensure that the rubber plugs are in place for all holes not occupied by cables and that thegrommet sits squarely in its receptacle before tightening the gland nut to secure the seal.

Note that any pre-terminatedcables will need to have theconnectors staggered, as shown,lower left, in Figure 4-8, in orderfor them to pass through the holein the PonE unit housing

4.3.4 Assembling the RJ45 Connector

Shielded, weatherproof RJ45 connector shells are used for connecting the CAT5E cable, leading from thepower-on-Ethernet power supply and network connections, to the Horizon Compact.

Note: Shield and drain wire MUST be connected to metal head shell of RJ45 connector at BOTHends of outdoor cable!

Two different styles of connector have been used in production. For Horizon serial numbers ending in“999” or less, an RJ45 “snap in” type in-line housing is used. For serial numbers ending in “1000” orhigher a “push fit” style is used. Both styles are not compatible and do not mate with the respectivefemale connector on the horizon chassis.

“Snap fit” Style

The connector shell must be assembled in a specific manner for it to correctly connect to the HorizonCompact unit. The CAT5E cable is terminated as a straight through connection with a shielded RJ45connector. This RJ45 connector has to be assembled into the weatherproof connector shell oriented asshown in Figure 4-10.

This connector relies on a gland nut to hold the assembly firmly together. The CAT5E cable is threadedthrough all the components of the connector housing (see Figure 4-11) before the cable is terminated asa straight through connection with a shielded RJ45 connector. Once terminated, the RJ45 connectorslides back into the connector housing which accepts the tab on the RJ45 connector. Screw the ferruleinto the connector housing as far as it will go, ensuring that the ‘O’ ring creates a tight seal with theconnector housing. Slide the compression seal into the ferrule, noting that the keyways have to mate withchannels in the ferrule. While ensuring that the RJ45 connector is firmly seated in the connector housing,tighten up the gland nut to secure the complete connector assembly.

CAUTIONUsing a cross-over connection

will damage the HorizonCompact. Only use straightthrough cable connections.

CAUTIONEnsure that shield foil and drain wire of CAT5E outdoor cablesare positively connected to the metal head shells of the RJ45

connectors at BOTH ends of the cable!

CAUTIONFor Release 1.1 and earlier, connectthe RJ45 connector to the Horizon

Compact BEFORE applying power tothe system at the PonE/surge unit.

This does not apply to Release 1.2 ofthe PonE adapter.

DragonWave Inc.22


4.4 Ethernet Cabling – Copper Interface – Option 2

The composite cable provided with this option has an overall shielding and contains two shielded CAT5Ecables, a power feed cable and a drain wire/shield connection. All are terminated at the Horizon Compactend in a single MIL specification, multi-pin, connector. This is connected to Port 1, with the vacant Port 2location fitted with a weatherproof blanking plate. This option does not support PonE power feeds.

The data feed end of the CAT5E cables are terminated with shielded RJ45 connectors. The blue cable isthe data and optional in-band management connection. The grey cable is the optional out-of-bandmanagement connection. The maximum length of the cable is 100 m.

Both CAT5E network cables and the power feed must be protected from induced voltage surges using aDragonWave Surge arrestor Unit. The drain wire/shield must be connected to ground within the surgearrestor unit.

DO NOT CONNECT SHIELDED RJ45 CONNECTORS TO CABLES CONNECTING THE SURGEARRESTOR TO THE NETWORK SWITCH.

For detailed power supply connections see Section 5.2.

5.0 Powering the Horizon CompactBefore an active management session can be started on the Horizon Compact, power needs to beprovided to the unit. Read this section completely before applying power to the Horizon Compact.

5.1 Copper Interface – Option 1

The Horizon Compact with copper interface receives its power over the Ethernet connection to Port 1using a DragonWave proprietary technique. To integrate the power onto the Ethernet cable requires theuse of a DragonWave Power on Ethernet (PonE) power integrator/surge arrestor. There are two versionsof this unit – an outdoor rated unit and an indoor rated unit. Both DragonWave PonE units also includetransient and surge suppression components to protect the power supply and network from lightninginduced surges and transients.

Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards.

CAUTIONOnly use a straight-through Ethernet cable to connect the Horizon to the PonE/surge unit.Incorrectly wired cables will cause an alarm condition on the PonE adapter and the HorizonCompact will not power up.

5.1.1 Using the Outdoor PonE Unit

Figure 5-1 Connecting Power Using Outdoor PonE Unit – Copper Interface Option 1

Caution

Ensure correct voltage polarity before connecting external DC supply to HorizonCompact Unit.

The DC feed into the equipment shall be protected by a 3A rated over protectiondevice provided as part of the building installation.

Do not mix AC/DC adapter and site 48 V DC supplies.

It is recommended to use an isolated ±48VDC supply where both inputs arefloating (neither side grounded), or the isolated AC/DC adapter option. In caseswhere the site supplied ±48VDC is not isolated and has the +ve (return) sidegrounded, the optional green jumper wire provided must be used to connect the48V “RTN” to the ground lug connection inside the PonE box.

DragonWave Inc.26


5.1.2 Using the Indoor PonE Unit

Figure 5-2 Connecting Power Using Indoor PonE Unit – Copper Interface Option 1

5.1.3 Steps to Connecting Power

1. Connect Port 1 of the Horizon Compact to the correct socket on the PonE/surge unit using astraight through, shielded, Ethernet cable (see caution above).

2. Connect the Ethernet port on the PC to the network input socket on the PonE/surge unit, using astraight through Ethernet cable, with an unshielded RJ45 connector.

Ensure that you have connected the PC and Horizon to the correct RJ45 sockets on the PonE/surge unit(see Figure 5-1).

3. Once the PC and Horizon Compact are connected to the PonE/surge unit, you may connectpower to the PonE/surge unit. This will supply power to the Horizon Compact unit. An incorrectlywired system will cause the PonE/surge unit to prevent the Horizon Compact from powering up.This protects the Horizon Compact from incorrectly terminated power feeds.

Note that the PonE adapter supports redundant power supplies.

CAUTION

Do not mix AC/DC converter and site 48 V DC supplies for power redundancy.

Use of ISOLATED 48 VDC supplies is recommended. For non-isolated site-supplied 48VDC where the “Return” (positive) side is grounded, use the optionalgreen jumper wire to connect 48VDC “RTN” to internal ground inside the PonE.

For Release 1.1 and earlier, do not connect a PC or other network device (e.g.network switch) to the right hand RJ45 sockets on the PonE adapter. -48 V DC ispresent on these connectors which may destroy the connected device. Connectonly a Horizon Compact unit to the right hand RJ45 connectors.



5.1.4 PonE Status LED

Both the Outdoor and Indoor rated PonE units have a green status LED (see Figure 5-3) which indicatesthe status of the power-up cycle. When power is applied to the PonE adapter, prior to it attempting toapply power to the Horizon Compact, the PonE management system checks for under/over-voltage andopen or short circuit conditions. If any such condition exists, then the PonE adapter will not apply power tothe Horizon Compact. The status LED signals the condition of the PonE system if this should occur (seeTable 5-1). If the fault condition clears, the system will then attempt to provide power to the HorizonCompact unit, but the LED will continue to indicate that a current/voltage problem had occurred (Alarmhistory). The LED may be reset by pressing the Alarm Reset button (the Reset button is located in the topleft corner of the PonE adapter printed circuit board – see Figure 5-3) or recycling the power feed to thePonE adapter.

Incorrectly wired CAT5E cables can cause open or short circuit conditions, so this feature protects theHorizon Compact from incorrectly applied power. The PonE power unit will also shut-down when theHorizon Compact is disconnected from the PonE adapter (NTWK to Horizon port cable disconnected).

5.2 Copper Interface – Option 2

A shielded composite cable is available, comprising two CAT5E cables and two twisted pairs power feedcables in a single sheath, terminated at the Horizon Compact connection end in a single MILspecification, multi-pin, connector. The MIL style connector plugs into Port 1 on the Horizon Compact. Fornetwork Ethernet connections see Section 4.4.Both CAT5E network cables and the power feed must be protected from induced voltage surges using aDragonWave Surge arrestor Unit. There are two versions available – an outdoor unit and an indoor unit.

DragonWave Inc.30


5.3 Optical Interface

In the copper interface version, power is fed to the Horizon using PonE techniques via the Ethernetconnection to Port 1. In the optical version, this is not possible, so power is fed via the connection to Port2. Port 2, on the optical interface variant, is equipped with a weatherproof MIL style multi-pin connector,which incorporates an Ethernet connection and a power feed (NOT PonE) connection.

5.3.1 Using the Composite Cable

A composite cable is available that includes two CAT5E cables and power feed wires and is terminated atthe Horizon end with the MIL style connector compatible with the Port 2 connection. One of the CAT5Ecables (grey) provides Ethernet connection to Port 2 for optional out-of-band management. The remainingCAT5E cable (blue) does not need to be terminated.

Note that the Ethernet connection (where used) and power feed to Port 2 must be fed via a DragonWaveSurge arrestor Unit to protect the network and power systems from transients. Either the Indoor orOutdoor Surge arrestor unit may be used depending on the installation. See Section 4.4 for more detailson wiring this option.

Where distances prevent the use of the composite cable due to power feed loss, a special “Y” feedadaptor cable is available that allows customer provided, heavier duty, wires to be spliced into the powerfeed connection. The gland fitting on the DragonWave surge arrestor unit accepts and seals a roundcable with a jacket diameter between 0.35 and 0.62 inches. The power terminal block will accept up to amaximum of 14 AWG wires. An RJ45 Ethernet port connection is also available on this “Y” adapter cable.

Note that the OOB management connection (where used) and power feed to Port 2 must be fed via aDragonWave Surge arrestor Unit to protect the network and power systems from transients. Either theIndoor or Outdoor Surge arrestor unit may be used depending on the installation. See Section 4.4 formore details on wiring this option.

Figure 5-7 shows this arrangement showing how network and power circuits are protected by using theDragonWave Outdoor Surge arrestor Unit. If the suppression unit is installed indoors, then theDragonWave Indoor surge arrestor Unit may be substituted using the same connections.

6.0 Initial ConfigurationThere are a number of configuration steps that need to be carried out before the Horizon Compact canbecome operational. It is recommended that these steps be performed prior to mounting the system onthe tower. These steps relate to:

• radio bands

• frequency channels

• IP address information

Once this information has been correctly entered, the Horizon Compact system is ready for installationand system alignment.

The Horizon Compact can be configured using Telnet or the Web interface.

Before attempting to log on you must configure the network parameters of your laptop, or PC, so that theyare in the same domain as the Horizon Compact default IP address and subnet mask values.

By default, the IP address of a Horizon Compact system is 192.168.10.100 and the subnet mask is set to255.255.0.0. Use this IP address to communicate with the unit, using either Telnet or the Web browser. Acomplete set of CLI commands is available for use with Telnet (See Appendix A).

For the copper interface, connect your laptop or PC Ethernet port to Port 1 (GigE port) on the HorizonCompact using a straight through Ethernet cable. For the optical interface, you will need to connect yourPC to Port 1 of the Horizon via an optical switch. By default the management option is set to “inband”,which will allow management through the Port 1 data port.

Note: If the management interface type happens to be set to “out-of-band”, management through Port 1(GigE port) will not be possible. In this case connect your laptop or PC to the Horizon Compact via Port 2.In both copper and optical Horizon variants, Port 2 has a copper interface.

6.1 Secure Management Access

There are two management system access options available - DragonWave Default and EnhancedSecurity. When you purchase a system you will be able to select one or the other, but not both. If theEnhanced Security option is chosen and configured, you cannot revert to the DragonWave default option.Both Telnet and Web management methods are secured by the access option chosen.

WARNING:

With the Enhanced Security option, if you lose, or forget, the SuperUser password, and DragonWave proprietary access is disabled,there is no way that you can re-gain Super User access to the system,without shipping the system to DragonWave for recovery.

WARNING:

With the Enhanced Security option, if you need to ship the system toDragonWave for service, the Super User must ensure thatDragonWave proprietary access is enabled before you ship, byissuing the CLI commands set dw access on and save mib.

DragonWave Inc.34


6.1.1 DragonWave Default

Secure management access is controlled by a user name and password. The default Super User name is“energetic” and the default password is “wireless”. The system allows any format for user passwords(except the use of special characters), but does not allow a duplicate name or password. Also, an existinguser name cannot be used as a password.

The default system allows DragonWave personnel unhindered access to the system using a proprietaryaccess code. This may be necessary if default Super User parameters have been changed and havebeen forgotten, or remote access is required to troubleshoot the system.

6.1.2 Enhanced Security

With the Enhanced Security option, an initial Super User name and password are provided byDragonWave to the customer. This can be changed by the customer (Super User), once logged on.DragonWave proprietary access is also disabled, meaning that DragonWave personnel will not be able togain access to the system using the DragonWave proprietary access code, unless the Super Userspecifically allows it (set dw access on/off). If the Super User forgets the password, the system cannotbe accessed by the Super User and hence by DragonWave. For any DragonWave diagnosticsprogrammes, or Merlin applications, to work, DW access must be enabled.

The system forces the Super User to enter user names and passwords that have a higher security ratingthan those allowed in the DragonWave default option.

Passwords must be at least eight characters long and contain at least one of each uppercase alphacharacter, lowercase alpha character, numeric character and special character (! " # $ % & ' ( ) *+ , - . / : ; < = > ? [ \ ] _ ` { | } ~). Also, more than two repeated characters in apassword are not allowed.

Passwords are fully encrypted and are not visible to any user. Forgotten passwords can never berecovered.

The Super User can enter NOC and Admin user names and passwords into the system but cannotchange NOC or Admin user passwords once entered. The NOC and Admin users can change their ownpasswords as required. The Super User can delete any NOC or Admin user from the system. The SuperUser can change his/her own password when required.

WARNING:

With the Enhanced Security option, DragonWave Inc. access must beenabled (set dw access on) in order to run any DragonWavediagnostic programme or Merlin application.



6.2 Logging On

6.2.1 Using Telnet

From the DOS Command Prompt, or from the Windows Run option, type:

telnet 192.168.10.100 and press Enter.

When the Telnet window appears press Enter again to reveal the logon prompt.

When prompted, enter the Super User name and password. For the DragonWave default access optionthe Super User name is “energetic” and the password is “wireless”. For the Enhanced Security option,use the unique Super User name and password provided to you by DragonWave.

Successful logging on is indicated by the CLI cursor (->) being displayed.

Note that after 10 minutes of inactivity, you will be automatically logged off the system.

6.2.2 Context Sensitive Help

Full context sensitive help is available for all CLI commands. Type ? followed by a partial command toreturn a list of all commands that match the entry, with an explanation as to how each command is used.Type a command followed by ? to return a list of all variants of that command. See Appendix A – CLICommand List for an alphabetical list of CLI commands.

6.2.3 Using the Web interface

The Horizon Compact Web interface is disabled by default. You must use Telnet to enable the Webinterface by issuing the CLI command set web server on press Enter.

Open a Web browser and, in the “Address” or URL field at the top of the page, enter the IP address of theHorizon unit (default is 192.168.10.100) and press Enter. If your laptop or PC has been correctly set up,you will be prompted for the user name and password. Type in the Super User name and password. Thesame security access option selected when you purchased the system is also applied to the Webinterface. For the DragonWave default option the Super User name is “energetic” and the password is“wireless”. For the Enhanced Security option, use the unique Super User name and password provided toyou by DragonWave. The Horizon Compact Home Web page will be displayed.

6.3 Configuring Radio Band and Frequency Channels

Both Horizon Compact units in a system (near and far end) have to be configured with the same radioband. Volume 3 of this manual lists all the radio bands supported by the Horizon Compact system. Theradio band selected must match that for which the Horizon Compact units have been manufactured. Onlythose radio bands for which the radio can be configured are available for selection. The radio band willalso be dictated in the wireless licensing documents.

Typical radio band configuration selections have the format “fcc23_3_50”, “etsi23_3_14” ,“ul_fcc24_1_40” etc.

For licensed radio bands, the Horizon Compact units at each end of the link have different frequencybanks allocated to them. One unit will be allocated the “LOW” bank and the other the “HIGH” bank. This isindicated on the label attached to each unit (LOW or HIGH). Wireless licensing documents will indicate atwhich end of the link each should be located. The radio part number, that is stored in the system,determines if it is a LOW or HIGH unit and automatically configures the correct frequency bank for eachunit.

For unlicensed radio bands Horizon Compact units have the same type of radio at each end of the linkand do not have a LOW or HIGH indication on their labels.

DragonWave Inc.36


Each bank contains a number of frequency channels, of which only one will be selected. Once again theactual frequency channel will be dictated in the wireless licensing documents. Note that when using 2Horizon Compacts on the same data path, non-overlapping channels are required when operating above16QAM. If, however, you must use co-channel operation, then consult DragonWave for installationguidance and installation mount enhancements that are required.

You also need to configure the system mode (determines bandwidth and throughput parameters).

Use the following procedures to configure the radio parameters:

6.3.1 Using Telnet

1. Type the CLI command: get radio band and press Enter. The system will respond withthe currently configured radio band and a list of all supported radio bands

2. Type the CLI command: set radio band <radio band> and press Enter, where <radioband> is the required radio band

3. Type the CLI command get system mode and press Enter. The system will respondwith the current mode plus a list of allowable modes for the selected radio band.

4. Type the CLI command set system mode <Horizon mode> and press Enter. Themode follows the format of hc< channel bandwidth >_< speed >_<modulation>. Forexample, for a 50 MHz channel bandwidth with average Horizon speed of 110 Mbpsusing 16QAM modulation, enter set system mode hc50_110_16qam . Note that forunlicensed frequencies the mode includes “ul” in the mode descriptor. For examplehc40_ul_212_128qam.

5. Type the CLI command get system speed and press Enter. The current system speedwill be displayed. This, by default, will be the maximum speed supported by yourpurchased licensed speed key. Note that the mode configured in step 4 will determinethe speed available to the system and cannot exceed the licensed speed, regardless ofthe mode selected.

6. To reduce the throughput speed to a figure less than the licensed speed, use the CLIcommand set system speed <speed>, where<speed> is in Mbps and can be adjustedin 1 Mbps increments.

7. Type the CLI command get frequency bank and press Enter. A list of frequencies isdisplayed.

8. Licensed only - Locate the frequencies on the displayed list that match those found onthe wireless license documents, and note the index number/letter on the left of the list(case sensitive)

9. Unlicensed only – The displayed list will show “Go” and “Rt” frequencies. One end ofthe link must be configured with a “Go” frequency and the other configured with thecorresponding “Rt” frequency. Either end of the link can be configured as “Go” or “Rt”.

10. Type the CLI command set programmed frequency <index number/letter> and pressEnter, where <index number/letter> is the same as that found in step 8 for licensed, orstep 9 for unlicensed, installations

11. Unlicensed only – Determine the size (in cm) of antenna to be used with yourunlicensed system. Type the CLI command get antenna size and press Enter. Theallowable antenna sizes are displayed, along with a corresponding index number. Notethe index number that corresponds to the size of antenna to be installed.

12. Unlicensed only - Type the CLI command set antenna size <index number> andpress Enter, where <index number> is the index number determined in step 11. Note:setting the antenna size sets the transmit power to the maximum allowed for theantenna size entered, even if the power had been previously set to a lower value. You



may need to readjust the transmit power to the desired level (set transmit power<power>).

13. Type the CLI command save mib and press Enter. This command saves the enteredinformation to memory, but does not yet apply it.

Note: You will need to issue the CLI command reset system to apply the changes and make themeffective. Optionally, this can be left until all the initial configuration parameters have been entered beforeissuing the command (See 6.4.1 step 5).

6.3.2 Using the Web interface

1. From the Home page select the “Configuration” menu option and then select the“Frequency and port configuration” option

2. Use the drop down menus on the Web page for entering or changing the radio bandand the programmed frequency. For licensed systems, the frequency bank “txLow” or“txHigh” will be pre-determined (HIGH or LOW Horizon label)

3. Return to the “Configuration” menu and select the “System Configuration” option

4. Use the drop down menu to select the desired system mode

5. click on the “Save settings” button

Note 1: For unlicensed systems, you cannot configure antenna size using the Web interface.

Note 2: You will also need to click on the “Reset system” button to make these entries effective.Optionally, this can be left until all the initial configuration parameters have been entered before issuingthe command (See 6.4.2 step 5).

DragonWave Inc.38


6.4 Configuring IP Address Values

When shipped from DragonWave, the Horizon Compact is configured with a default IP address(192.168.10.100) and subnet mask (255.255.0.0). The default address is used to communicate with theHorizon Compact for initial configuration purposes, such as entering the IP address that the unit will havein the network to which it is to be connected. IP address information is entered in the following manner:

6.4.1 Using Telnet

1. Type the CLI command set ip address <nnn.nnn.nnn.nnn> and press Enter, where<nnn.nnn.nnn.nnn> is the desired IP address in standard format

2. Type the CLI command set subnet mask <nnn.nnn.nnn.nnn> and press Enter,where <nnn.nnn.nnn.nnn> is the desired subnet mask in standard format

3. Type the CLI command set default gateway <nnn.nnn.nnn.nnn> and press Enter,where <nnn.nnn.nnn.nnn> is the IP address of the default gateway in standardformat

4. Type the CLI command save mib and press Enter. This command saves the enteredinformation to memory, but does not yet apply them.

5. Type the CLI command reset system and press Enter, followed by “Y”. Thiscommand resets the system and applies all the radio and IP changes just made.Note that resetting the system disrupts traffic.

Once the system has reset, you may not be able to communicate with it without changing your laptop orPC networking parameters to match the new IP address values programmed into the Horizon Compact.

Note that the reset system command is not always required when making configuration changes, but thesave mib command is always required. Commands that require a reset system will be indicated on thescreen.

6.4.2 Using the Web Interface

1. From the Home page select the “Configuration” menu option and then select the “IPconfiguration” option

2. Enter the IP address, subnet mask and default gateway values, using standardformat, in their respective fields

3. Click on the “Submit” button

4. Click on the “Save settings” button

5. Click on the “Reset system” button

Once the system has reset, you may not be able to communicate with it without changing your laptop orPC networking parameters to match the new IP address values programmed into the Horizon Compact.

The system is now configured and capable of passing traffic once the Horizon Compact units areattached to antennas, mounted at each end of the link and aligned.



6.5 Recovery of IP Address and Serial Numbers

This feature is only available to systems that are running the DragonWave Default Access option.For the Enhanced Security Access option, the system will need to be returned to DragonWave forthe recovery to be performed.

In the event that the Horizon Super User name and password, or IP address has been lost, forgotten, ormisconfigured, you will need to contact DragonWave ([email protected]). DragonWaveTechnical Support will provide the Merlin recovery utility that, using a proprietary protocol, can recover theconfigured IP address parameters and/or reset the Super User name, Super User password and IPaddress parameters to the factory default values (energetic, wireless; 192.168.10.100, 255.255.0.0). Inaddition it reports the system serial number.

The Merlin utility runs on a PC running the Windows operating system and requires a one-time-userecovery key provided by DragonWave. Proof of ownership and proof of authority must be providedbefore the key will be issued. When Merlin is invoked, the Horizon unit responds with the requiredinformation, which is saved in a text file, located in the same directory as the Merlin application.

6.6 Changing and Adding User Names and Passwords

User account names and passwords can only be configured using a Telnet session. Only the Super Usercan change or add user account names or passwords. There are three user account levels as shown inTable 6-1

Table 6-1 User Account Levels

AccountLevel

Number ofAccountsAvailable

Functionality

Super User 1 Super User account has control over the usernames andpasswords for both the NOC and Admin accounts. Cancreate backup file of NOC and Admin accounts onto an FTPserver, restore system settings and load new software

noc 5 Network Operations Centre (NOC) accounts allow fullcontrol over the configuration of the Horizon Compactsystem, including setting the frequency and IP address.NOC accounts may also backup the Horizon Compactsystem settings to an FTP server and restore the systemsettings from an FTP server. NOC accounts cannot createor change user accounts, or issue any security relatedcommands (ex: set http secure access)

admin 50 Admin accounts allow operational management of theHorizon Compact system but have some restrictions forchanges to configuration

No default noc or admin user accounts are configured when the Horizon Compact leaves the factory.Account names and passwords are case sensitive. There can be no duplication of names or passwordsacross all user levels. A password cannot be the same as a user name. More strict password structuresare required for the Enhanced Security Access option.

DragonWave Inc.40


6.6.1 Changing the Super User Name and Password

It is recommended that the default, or supplied, Super User name and password be changed as soon asthe Horizon Compact system is aligned and operational.

Depending on the access security option chosen when the product was purchased, the method ofchanging the Super User name and password is different.

Note: When you change the Super User name and/or password, record the new values in a safe place. Ifyou forget the new values, there is no way of retrieving them from the system. If the Horizon Compact issupplied with the DragonWave default access option, you will have to contact DragonWave to arrange aSuper User reset (24 hour support number 613-271-7010, or [email protected]). If thesystem has been supplied with the Enhanced Security option, you will no longer be able to gainaccess to the system.

DragonWave Default Access

To change the Super User name and password use the CLI command set super user and press Enter.Follow the prompts.

When the new name and password have been accepted enter the CLI command save mib and pressEnter. This will save the changes in non volatile memory. Failing to save the mib will result in changesbeing lost in the event of a power failure, or system reset.

Enhanced Security Access

To change the Super User name and password use the CLI command set super user and press Enter.Follow the prompts. Note that after entering the new name and password, the system requires the oldpassword to be correctly entered before it accepts the entries.

The Enhanced Security Access option also allows the Super User to change only his/her password. Usethe CLI command change password and follow the prompts. Note, again, that the system requests thecorrect input of the old password before entry will be accepted.

When the new name and password have been accepted enter the CLI command save mib and pressEnter. This will save the changes in non volatile memory. Failing to save the mib will result in changesbeing lost in the event of a power failure, or system reset.

Once entered, all passwords are encrypted and are not visible to any user, regardless of account level.



6.6.2 Adding or Changing noc User Accounts

Up to five noc user accounts can be configured. The process is slightly different depending on if you havethe DragonWave Default Access option or the Enhanced Security Access option.

Four mountingclips

Four mountinglugs

Antenna portWaveguide adapter

7.0 Antenna Mounting and Tower SpecificationsThe Horizon Compact unit clip mounts onto a range of antennas, providing a variety of gain and rangeoptions. The same mounting system is used for all sizes of antenna.

Figure 7-1 Horizon Compact showing clip mount features

The Horizon Compact unit has four, integral, spring loaded, mounting clips. DragonWave antennas havefour mounting lugs, to which the mounting clips attach. The antenna port and the waveguide adaptor of theHorizon unit, fit together, and are weather-sealed with a lubricated ‘O’ ring located on the outside surfaceof the antenna port. See the step by step mounting instructions below:

Caution

The interface between the antenna port and the waveguide adaptor isvery tight and care must be taken both when mounting and removing theHorizon to/from its antenna.

1. Ensure O-Lube supplied with Horizon is applied to the O-ring prior to mating the Horizon to theWaveguide adaptor.

2. With the Horizon unit (waveguide side uppermost) resting on a firm, flat surface, carefully place theAntenna on the Horizon and loosely engage the four clips into the mounting lugs. DO NOT try toforce the antenna onto the Horizon manually. The concentric alignment of the Horizon toadaptor is critical during engagement to prevent damage and metal galling.

3. Ensure that the drain holes in the antenna are positioned such that with the Horizon in the verticalorientation, one drain hole points down and the drain hole at 90

ois on the same side as the RF

connector.

4. Push down both clips on opposite sides of Horizon, at the same time, drawing the Horizon andadaptor together until they are fully seated.

5. Repeat with the remaining two clips

Note: The waveguide interface to the antenna is circular. The antenna is not polarization specific. Thepolarization is determined by orientation of the Horizon Unit. A visual polarization indicator (an “arrow”)exists on the Horizon housing. If the Horizon is installed with the polarization indicator in the vertical planethen the Horizon is in vertical polarization. Similarly, if the polarization indicator is in the horizontal planethen the Horizon is in horizontal polarization.

DragonWave Inc.50


7.1 Polarization

Horizon Compact units that operate on licensed radio bands use a diplexer system to simultaneouslyhandle transmitted and received signals to/from the antenna. In this case, both transmit and receiveantenna elements must have the same polarization.

For unlicensed radio band units, an orthogonal mode transducer (OMT) is used to allow the radio tosimultaneously transmit on one polarization and receive on the opposite polarization.

7.1.1 Licensed Radio Bands

Both Horizon Compact units must be mounted on the pole/tower oriented for the same polarization. i.e.both vertical polarization, or both horizontal polarization.

Caution

Cross-polarized radios or antennas result in the signal strength being 20-30 dB below expected RSL levels! Ensure both radios have the sameorientation (vertical or horizontal).

The radio frequency polarization is indicated by an arrow molded into the Horizon Compact housing.Attach the Horizon Compact to the antenna so that the arrow points either vertically or horizontally, asrequired, when the assembly is attached to the mounting post or tower. With the arrow horizontal(pointing to the left) – horizontal polarization; with the arrow vertical (pointing upwards) – verticalpolarization. For licensed frequencies, the required radio polarization is defined in your licensingdocumentation.

Figure 7-2 Horizon Compact polarization marker

PolarizationMarkerThis Horizon unitis shown mountedfor horizontalpolarization (arrowhorizontal)



7.1.2 Unlicensed Radio Bands (UL24)

For unlicensed radio bands, regulatory bodies require that both radios in a link have to be cross-polarized. This means that the antenna polarization of the transmitter at one end of the link is vertical andthe transmitter polarization at the other end is horizontal.

The radio at one end of the link transmits with vertical polarization and receives with horizontalpolarization, while the other end transmits with horizontal polarization and receives with verticalpolarization.

The radio frequency polarization is indicated by an arrow molded into the Horizon Compact housing.

Attach the Horizon Compact to the antenna so that the arrow points either vertically or horizontally, asrequired, when the assembly is attached to the mounting post or tower. With the arrow horizontal(pointing to the left) – horizontal polarization; with the arrow vertical (pointing upwards) – verticalpolarization. For unlicensed frequencies, one end of the link has to have vertical polarization and theother horizontally polarization (cross-polarized). It does not matter which end of the link has a specificpolarization.

7.1.2.1 Unlicensed (UL24) Antenna Information

This device has been designed to operate with the antenna types listed in Table 7-1, and having amaximum gain of 43.7 dBi. Antennas not included in this list or having a gain greater than 43.7dBi arestrictly prohibited for use with this device. This device has integrated antennas.

75 cm (2.5 foot) Andrews VHLP2.5-26DW 43.7dBi

Caution

For 24 GHz Unlicensed Band, radios MUST be cross-polarizedi.e. Vertical polarization at one end and horizontal polarization at the other.It does not matter at which end either radio is installed.

DragonWave Inc.52


7.2 Antenna Location

For both licensed and unlicensed systems, antenna location, relative to nearby obstacles, is an importantfactor to consider when planning an installation. For systems mounted on buildings, roof edges andparapets, the roof surface itself, air conditioning plant, other antenna systems, walls and overhead objectsare all considered potential obstacles. On tower mounted systems you must consider the proximity ofother antenna systems and mounting hardware.

Near field effects, resulting from a number of minor radiation lobes normally found around antennasystems, can reflect off nearby objects and interfere with the normal reception of the radio. Reflectedwaves can also change their polarization. This is especially important for unlicensed systems.

Consider an unlicensed installation that transmits with vertical polarization and receives with horizontalpolarization. If the near field vertically polarized transmitted signal reflects off an obstacle located tooclose to the antenna system, then the reflected signal changes its polarization to horizontal, which is thesame polarization as the receiver. This causes the receiver to “swallow” the transmitted signal, resulting inreceiver “swamping”, excessive noise and the inability to receive the signal from the far end of the link.Ensuring that obstacles and objects are not too close to the antenna system will avoid this problem.As a “rule of thumb”, for both licensed and unlicensed installations, ensure that you maintain an angle of45 degrees, or greater, between the far side of the highest part of an obstacle and the underside of theantenna. The diagrams in Figure 7-3 illustrate this approach. Also, remember to apply this rule in alldirections around the antenna, above, below and to each side. An exception to this rule can be appliedwhen the antenna is positioned 12.5 m (40 ft) or more from the edge of a roof clear of obstacles (a roofedge is considered an obstacle). In this case the antenna need not be higher than 2.5 m (8 ft) above theroof surface. For more details on antenna placement for unlicensed systems refer to Volume 2 of thismanual.

8.0 Grounding, Power and Surge ArrestorsNote: For effective protection against lightning-induced surges, proper grounding and shieldingpractices MUST be followed for the ENTIRE installation. Consult DragonWave Inc. Technical Note:HC-TN-001 Horizon Compact PonE and Quick Reference Guide before installation!

The Horizon unit must be grounded using a minimum of 6 AWG copper wire attached to any of the eight,metric thread (M6 x 1.0), grounding points available on the Horizon case, as shown in Figure 8-1. Two 12mm long bolts are supplied.

Surge arrestors and lightning protection is built into the Horizon unit.

The Ethernet and PonE cables must be properly protected at the end of their run as they enter thebuilding. Before Ethernet cables enter buildings, voltages shall be clamped down to SELV by approvedtype primary protectors.

For the copper interface option, proper use of the DragonWave Horizon PonE unit provides lightning andsurge protection for the connected network. The PonE unit shall be installed according to local ElectricalSafety Codes.

For the optical interface, proper use of the DragonWave surge arrestor unit protects the optionalmanagement Ethernet connection (if used) and the power supply.

Figure 8-1 Horizon Compact case grounding point

GroundingUse 6 AWG or larger copper wire to connect from Horizon case grounding point to ground.There are two grounding points on each of the four sides of the Horizon case.Note that all grounding points have a metric thread, M6 x 1.0. Two 12 mm long bolts are supplied.

DragonWave Inc.56


8.1 Power on Ethernet (PonE)

The copper interface variant of Horizon operates on -48 VDC and employs a proprietary Power onEthernet solution. The Horizon Outdoor and Indoor Power on Ethernet surge arrestor units provideintegration of -48 VDC and data signals on the straight through Ethernet data cable. Power is notintegrated onto the optional out-of-band management Ethernet cable.

Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards.

The surge arrestor uses RJ45 connectors for the Ethernet cables and screw-terminals for the -48 VDCpower connections. Dual -48 VDC power connectors are provided, allowing for the connection ofredundant power supplies.

The surge arrestor unit contains protection against cable transients and power surges caused by lightningor other sources. The surge arrestor is installed at the opposite end of the CAT5E/PonE cables to that ofthe Horizon unit and protects the network.

To ensure adequate lightning protection, the PonE surge arrestor unit must be properly grounded.

Horizon consumes a nominal 20 Watts (standard power), or 40 Watts (high power variant) from the -48VDC supply. All eight of the wires in the Ethernet cable are used to carry power to the Horizon Compactunit. The Power on Ethernet surge arrestor unit is rated at 2 amps.

The PonE unit has a protection feature that prevents power from being supplied to the Horizon Compact ifit detects any under or over voltage/current conditions (see Section 5.1.4). Over or under voltage/currentconditions can occur if cables are incorrectly terminated.

CAUTIONFor Release 1.1 and earlier, serious damage to networkswitches or routers can occur if the network is plugged intothe connectors marked “TO HORIZON UNPROTECTED”.Power is fed to the Horizon unit along the same wires thatcarry Ethernet traffic to the Horizon unit. Unless you havethe Release 1.2 PonE adapter, do not, under anycircumstances, plug cables connected to the network intothe RJ45 connectors marked “TO HORIZONUNPROTECTED”.

CAUTIONOnly use straight through Ethernet cables to connect thePonE adapter to the Horizon Compact. Using cross-overcables will result in damage to the Horizon Compact unit.

CAUTIONUse shielded CAT5E cables with shields and drain wiresconnected to metal head shells of RJ45 connectors, at BOTHends of cable for all unprotected, outdoor cable runs toHorizon Unit!Use unshielded CAT5 cables and/or RJ45 connectors forprotected-side cable runs to network equipment.



Figure 8-2 Outdoor Surge Arrestor and Power Integrator

Cables are secured in the Outdoor PonE unit by means of the cable entry gland nuts. A special three-hole, rubber, grommet is provided to accommodate two CAT5 cables, plus a power feed cable (SeeSection 4.3.2). Cables with sheath diameters of between 0.35” and 0.62” can be accommodated whenthe special grommet is removed.

9.0 Preparing for AlignmentThe Horizon Compact and antenna assembly is attached to the mounting post, or tower, with aspecialized mounting bracket that allows fine orientation adjustment of the Horizon/antenna assembly.The same mounting bracket is used for all antenna sizes.

Visual alignment is achieved by rotating the assembly on the post, or tower, and positioning the assemblyso that the antenna is visually aligned with the target system before tightening the mounting bracketclamp. Final alignment is achieved using the azimuth and elevation adjustment bolts. Once alignment isachieved, the adjustment mechanisms are locked in place with lock nuts.

Figure 9-1 Mounting bracket with fine adjustment bolts

Final alignment is achieved by monitoring the received signal level (RSL) values as the system isadjusted for azimuth and elevation. The BNC Field Strength Monitor connection is used in conjunctionwith a voltmeter for RSL monitoring. See Section 9.1. Adjustments are made until the RSL value is at amaximum, which should be within ± 3 dB of the expected value (link budget figure).

9.1 Received Signal Level (RSL) Measurements

To accurately align the Horizon Compact to its far end peer, you need to monitor the received signal level(RSL). There are two recommended methods for monitoring RSL. These are:

1. Use the CLI command set alignment on to activate the alignment feature at the BNCconnector located on the side of the unit. Connect a voltmeter to the BNC connector. Thevoltage at this connector is linearly related to RSL and is 1 mV per dB e.g. -45 mV = -45 dB.Note that the centre connection on the BNC connector is positive, so to read negative values(to correlate with the negative RSL values) connect the negative pole of the voltmeter to thecentre connection.

Figure 9-2 Voltmeter connections to BNC field strength monitoring connector

2. Alternatively, readings can be made remotely via the Web interface, using the Tools – LinkAlignment menu option. An operator would then have to continually relay RSL readings, via aradio or cell telephone, to the rigger adjusting the positioning of the system.

BNC to bananajacks cables areavailable fromDragonWave

Preparing for Alignment61


9.2 Three Important Factors

When you prepare to align the radio antennas, you must consider three important factors:

1. the radiation patterns of dish antennas (main lobe and side lobes)

2. the need for a Clear Line of Sight (LoS)

3. the sensitivity of the alignment adjustment

9.2.1 Antenna Radiation Patterns

The dish antennas used for the DragonWave Horizon Compact have high gains and very narrow beamwidths, making antenna alignment a critical element of a successful installation. In addition to the mainantenna beam, or lobe, there are often side lobes. Care must be taken to ensure that alignment is madeto the main lobe and not onto a side lobe. If you align onto a side lobe, the RSL will be at least 20dB lessthan expected.

Table 9-1 Antenna Gains and Beam Widths – Selected Frequencies

9.2.2 Clear Line of Sight (LoS)

The DragonWave Horizon Compact requires a clear LoS between the units at each end of the link. Youmust be able to see an unobstructed view of the antennas from each end. Avoid obstacles that are closeto the LoS mid-way between antennas, but not blocking it, as this can have a negative impact on signalquality (Fresnel zone clearance). Also, ensure that antennas are mounted with adequate clearance fromroof tops, roof edges, walls and other obstacles (e.g. air conditioning plant) to avoid problematic near fieldeffects.

9.2.3 Alignment Adjustment Sensitivity

When aiming the antenna it cannot be over emphasized that you must rotate the adjustment nut(s) 1/10th

of a turn at a time between taking RSL readings (allow time for the RSL reading to update). One full turnof the adjustment mechanism can move the antenna through 1.6 degrees azimuth or 2.2 degrees ofelevation. Table 9-1 shows that the beam width of the typical antenna is often less than the amount ofmovement available with one full turn of the aiming adjustment.

10.0 Aligning the AntennasFollow the steps of the alignment procedure shown below. Note: ensure that the CLI command setalignment on has been entered at both ends of the link if you are using the BNC connector to measurefield strength.

At the first end:

1. Loosen the pan mechanism lock nuts

2. Pan or move the antenna horizontally across the entire range of adjustment to identifythe main lobe and the side lobes. The main lobe is approximately 2 degrees in width(depends on frequency and antenna size). The two major side lobes are approximately 5degrees apart. Adjust the antenna to the main lobe (approximately).

3. Tighten the pan mechanism lock nuts and loosen the tilt mechanism lock nuts.

4. Tilt or move the antenna vertically until you receive the strongest RSL reading.

5. Tighten the tilt mechanism lock nuts and loosen the pan mechanism lock nuts.

6. Pan or move the antenna horizontally to locate each of the lobes. Record the RSLvalues of each. Select the strongest RSL recorded and readjust the antenna to thisstrongest RSL reading.

7. Re-tighten the pan/tilt mechanism lock nuts to lock the antenna in place.

At the other end:

8. Repeat steps 1 through 7

Return to the first end:

9. Loosen the pan mechanism lock nuts.

10. Pan or move the antenna horizontally across the entire range of adjustment to identifythe main lobe and the two major side lobes. Adjust the antenna to the main lobe(approximately).

11. Tighten the pan mechanism lock nuts and loosen the tilt mechanism lock nuts.

12. Tilt or move the antenna vertically until you receive the strongest RSL reading.

13. Tighten the tilt mechanism lock nuts and loosen the pan mechanism lock nuts.

14. Pan or move the antenna horizontally and locate the strongest RSL reading.

15. Re-tighten the pan/tilt mechanism lock nuts to lock the antenna in place.

16. Repeat steps 1 through 15 as necessary to obtain maximum RSL reading.

Notes:

The RSL level should be within ±3 dB of predicted levels. Factors that contribute to low RSL levels are:

• incorrect antenna alignment - aligned to a side lobe and not main lobe

• improper polarization of antennas – one end horizontal and the other vertical

• path issues - obstructions such as trees, hills, or buildings within the beamwidth

• path clearance issues such as diffraction, partial obstruction, Fresnel zone issues

DragonWave Inc.64


10.1 Signs of a Healthy Link

You can be confident that a link is properly aligned and free of problems if the following readings areobtained during a Telnet or Web interface session with each end of the link :

• No alarms – use the CLI command get alarms and press Enter to return a list ofcurrent alarms – should be none that cannot be explained by network status

• Received signal level (RSL) within ±3 dB of link budget figure in clear weather. Usethe CLI command get modem statistics and press Enter to obtain the RSL reading.The Unchannelized power reading should be within 6 dB of the RSL reading. If theUnchannelized power drops below -75 dB, then it is likely that there is no signal beingpresented at the radio portion of Horizon Compact. Check alarms.

• Eb/No of 19 dB or higher – use the CLI command get modem statistics and pressEnter to display the Eb/No value

• Signal to Noise Ratio (SNR) of 24 dB or higher – use the CLI command get modemstatistics and press Enter to display the SNR value

• Equalizer Stress typically between 20 and 30, but never more than 150 - use the CLIcommand get modem statistics and press Enter to display the Equalizer stressvalue

• Rx Block Error Rate 0.00e+00 – use the CLI command get traffic statistics andpress Enter to display the Rx Block Error Rate. Rx Block errors are an indication ofloss of data frames. Note that there are residual Rx Block errors as a result of thealignment process.

• Transmit power typically set at the maximum for the radio band used – use the CLIcommand get transmit power and press Enter to return the configured transmitpower

• All sections operational – use the CLI command get health and press Enter to returnthe health status of all three sections of the system

The readings obtained using the CLI commands during a Telnet session can also be retrieved using theWeb interface. All items listed here are available on the left-hand pane of the Web interface and appearon each Horizon web page.


11.0 Advanced Configuration FeaturesDragonWave Horizon Compact has a number of optional advanced configuration features that may beapplied if desired. It is recommended that they only be applied once the Horizon Compact is satisfactorilyaligned and successfully carrying traffic. The following lists the features available:

• Radius Server UserAuthentication

• Modem Authentication

• VLAN Tagging • Threshold Alarms

• 802.1P Priority Tagging • Rapid Link Shutdown (RLS)

• Pause Frames • Simple Network TimingProtocol (SNTP)

• Horizon Throughput Speed • Adaptive Modulation

• Adaptive Transmit PowerControl (ATPC)

• Radio Redundancy

Each feature is described in this manual, but detailed configuration information for each can be found inthe Horizon Product Manual Volume 2 - Advanced Features.

11.1 RADIUS Server User Authentication

The DragonWave Remote Authentication Dial In User Service (RADIUS) server option enables users tobe centrally authenticated before being allowed access to a Horizon Compact unit. This adds anotherlayer of security by removing user access control away from individual units and moving it to a centralserver. However, all Horizon Compact units must have all approved users entered in the userauthentication list before the system will grant access at the appropriate user levels (admin, NOC, Super).

Up to five (5) RADIUS servers can be configured.

When one, or more, RADIUS server is configured, the username and password authentication system onthe Horizon Compact is bypassed, in favour of the RADIUS system. Access levels are still retained in thelocal Horizon Compact memory, so once a user is verified by the RADIUS server the access level isassigned by the Horizon Compact (provided that that user is a valid user on that unit). Any user that isvalidated by the RADIUS server, but is not found in the Horizon Compact user authentication list, cangain access to the unit but only at an admin user level.

If, on attempting to log in, a user does not receive a response from a configured RADIUS server, the userwill not be allowed to log in.

Only the Super User can issue any of the RADIUS “set” commands and view any of the security relatedentries returned with “get” commands (passwords, shared key etc..)

DragonWave Inc.66


11.2 Management VLAN TaggingNote: The configuration of Horizon Compact VLAN tagging is only necessary if you wish to restrictHorizon Compact management communications to a specific management VLAN.

The Horizon Compact system will pass user VLAN traffic transparently, independent of the HorizonCompact VLAN settings. The VLAN settings are for Horizon Compact management purposes and do notaffect user data or traffic. VLAN Standard IEEE 802.1Q is supported for Horizon Compact VLAN taggingand it accommodates up to 4096 VLANs within the “8100” VLAN range. Note that the Horizon Compactsystem handles Ethernet frame sizes up to 9600 bytes.

There are three parameters associated with Horizon Compact VLAN tagging:

1. Enable or disable VLAN tagging (set VLAN tagging [on/off])

2. Identify the VLAN tag id to be used with Horizon Compact (set VLAN tag [tag id])

3. Determine whether to allow Horizon Compact to match the VLAN settings in response toincoming frames, or whether to restrict responses to those incoming frames containingthe programmed VLAN tag. There are two modes (set network protocol strict [off/on])which are commonly known as “friendly” and “strict” mode.

i. “Friendly” mode. In this mode, Horizon Compact matches the VLAN format ofthe incoming frame. If an incoming frame contains a VLAN tag, then HorizonCompact responds with a VLAN tag matching the incoming frame. If theincoming frame does not contain a VLAN tag then Horizon Compact does notinsert a VLAN tag in the response. Frames generated by Horizon Compact(e.g. SNMP traps) will contain the programmed VLAN tag.

ii. “Strict” mode. Horizon Compact will only respond to frames containing theprogrammed VLAN tag. All other frames will be ignored. Frames generated byHorizon Compact (e.g. SNMP traps) will always contain the programmed VLANtag.

11.3 Quality of Service (QoS) Implementation in Horizon Compact

QoS implementation is best done on the ingress and egress portions of the transport network. As such,QoS should be implemented on the Ethernet switches. Once that implementation is in place, the HorizonCompact can be configured for QoS, should the potential for congestion exist.

Enabling QoS on Horizon Compact ensures that incoming packets are handled with a priority based onthe Class of Service (CoS) bits embedded in either VLAN (802.1p) packets, Super VLAN (Q-in-Q, ordouble tagged) packets, or the DSCP field in IP packet headers, or the exp field in the first MPLS header.The CoS bits have a numeric value, or a derived numeric value, ranging from 0 to 7, giving eight CoSlevels.

There are four CoS Queues within Horizon Compact, numbered 1 to 4. Any of the eight CoS levels canbe assigned to any of the four CoS Queues. Any arriving frames not having a CoS level assigned to themcan be classified at a level (0 – 7) based on the configured default CoS value (set cos default value [0though 7).

Each of the four CoS Queues can be assigned a :

• Committed Information Rate (CIR), which determines the guaranteed bandwidth allocated to aparticular Queue. By default each queue is allocated 25% of the maximum available bandwidth ofthe system.

• Committed Burst Size (CBS), which determines the amount of burst data that the Queue canmanage. By default each queue is allocated 25% of the available buffer size (16 MB).

Advanced Configuration Procedures67


Each of the four queues is serviced by a scheduler in a manner dependant on one of two configurablequeuing policies.These policies are:

• Priority Queuing• Weighted Fair Queuing

Expedite Queuing can also be configured for either policy, but the expedite queuing functionality (seeSection 11.3.4) differs between each policy.

11.3.1 Operation with Quality of Service Disabled

If QoS is disabled in the Horizon Compact system, all incoming frames are treated equally and areforwarded on a first-come, first-served basis. The system operates in a first-in-first-out (FIFO) basis.

If the Pause Frames feature (see Section 11.4) is enabled, pause frames will be sent to the connectedswitch when the input buffer is close to being full (internally set threshold). This allows time for the queueto empty prior to more frames being received and thus avoids packet loss. If QoS is enabled, the PauseFrames feature is not configurable.

11.3.2 Quality of Service – Priority QueuingIf the Priority Queuing policy is enabled in the Horizon Compact system, the scheduling mechanism canbe described as follows:

1. Select the highest priority queue which has a frame in it, and hasn’t used up its CIR budget

2. Send that frame

The priority queues are serviced by the scheduler always in the order 4, 3, 2, 1 with queue 4 always beingpolled first.

The operation of the Scheduler is affected by both the user-configurable CIR and CBS settings.

Horizon Compact can be configured to use priority bits found in VLAN packets, Super VLAN (Q-in-Q ordouble tagged) packets, or the DSCP field of IP packets, or the exp field in the first MPLS header. Withthe Super VLAN option the system can also be configured to use CoS information in either the “serviceprovider’s” tag (outer tag) or the “customer’s” tag (inner tag), in determining priority handling.

11.3.3 Quality of Service – Weighted fair Queuing (WFQ)

Priority Queuing scheduling has the drawback of wasting bandwidth when any of the queues’ bandwidthrequirements are below the set CIR for that queue. Any unused bandwidth allocated to a queue cannotbe redistributed to the other queues. Also, there is a possibility of starving the lower priority queues whenthe higher priority queues are over subscribed. WFQ helps in solving these problems.

In WFQ, each of the queues is assigned a weight. Each queue is also assigned a CIR which guaranteesthe minimum bandwidth for the traffic in that queue when congestion occurs. The queues are serviced inround robin fashion. If the traffic in a queue is less than its assigned CIR, then any unused bandwidth ofthe system is distributed among the queues proportional to their assigned weights. When a queue meetsits CIR, it is serviced only when bandwidth is not consumed by the other queues which have not met theirCIR.

11.3.4 Expedite Queuing

The Expedite Queuing function differs depending on if you are operating with priority queuing or weightedfair queuing (WFQ).

In the Priority Queuing policy, Expedite Queuing is a mechanism that allows one, or more, of the fourQueues to oversubscribe the CIR. This way higher priority queues can use excess bandwidth if neededwhile lower priority queues can use the leftover bandwidth. However, the expedite function must beenabled before this becomes active.

DragonWave Inc.68


In the WFQ policy, only one queue (queue 4) can be configured as the expedite queue. This is achievedby assigning queue 4 with a weight of zero (0) and enabling the expedite function. The traffic directed toqueue 4 will now be given priority up to its assigned CIR, but queue 4 will not be able to access anyavailable surplus bandwidth in the system. This will be shared by the remaining three queues based ontheir weighting values – the higher the weighting value, the greater the share of surplus bandwidth will beassigned.

11.3.5 Management Traffic

Slow bridge protocol services are handled by a special Queue inside the Horizon Compact. The Queueis not user-accessible. It is the highest priority queue in the system and it ensures management traffic ispassed at highest priority. It does not affect, nor is related to the 4 Queues within Horizon Compact. ThisQueue does not impact the operation of the 4 user-configurable CoS Queues.

Frames destined for the 01-80-C2-00-00-xx MAC addresses are sent to the internal Queue. Examples:STP, RSTP, MSTP LACP, Pause Frames, GARP (GMRP,GVRP), bridge broadcasts, OAM, LLDP, Portbased authentication are all sent to the internal Queue and are transmitted in an expedited fashion.Other frames that the user determines must be treated in an expedited fashion, such as “keep-alive”frames and MRP frames, must be assigned a CoS within the switch, then assigned to the appropriateQueue within Horizon Compact.

11.4 Pause Frames

Pause frames are generated by the weaker (slower) link when its forward pipe gets full. Pause framesinform the upstream device to “pause and stop sending traffic for a period of 5 mS”. When the PauseFrame feature is enabled, Horizon Compact generates pause frames to the Ethernet switch when theHorizon Compact receiving buffer hits the internally set threshold. The receiving buffer threshold is closeto 100 msec at GigE rate. At data rates lower than GigE, the data buffer will accommodate a lesseramount of data. The Pause Frame feature cannot be used when CoS/QoS is enabled.

11.5 Bandwidth Management

When you purchase a Horizon Compact system you receive a unit capable of providing a bandwidth(throughput speed) of up to 400 Mbps. However, the actual throughput speed achievable for any givensystem depends on the specific throughput speed key that you purchased with the system

You can upgrade your system to a higher licensed throughput speed (up to 400 Mbps) by purchasing anupgrade key and reprogramming your system. Any upgraded system can be reconfigured to a lowerthroughput speed as required, without losing the ability to return to the upgraded speed.

You may also downgrade a system to a lower licensed speed. A downgraded system may warrant arefund of licensing fees. A downgraded system cannot be returned to its former higher licensed speedwithout purchasing another licensed upgrade key.

11.5.1 Maximum Throughput Speed

The maximum throughput speed is determined by the Horizon Compact throughput speed key youpurchase, however, it is important to note that this is also determined by the Channel bandwidthassociated with the configured radio band, and the modulation scheme used. The channel bandwidth is afunction of the radio band, and the modulation scheme is automatically selected depending on thedesired maximum throughput. Configuring the Radio Band and System Mode of the system determinesthe maximum throughput and hence determines the modulation scheme applied.

Note: if you set a System mode of hc50_110_16QAM, the 110 figure indicates the maximum throughputspeed capability of that mode. However, if your licensed throughput speed key purchased fromDragonWave is less than this figure, your system throughput will be limited to the purchased licensedthroughput speed. Table 11-1 shows the modulation schemes that are selected for various OperatingModes when 23 GHz radio band with 50 MHz channel spacing is configured.



Table 11-1 Bandwidth Operating Mode and Modulation Scheme (50 MHz Channel bandwidth)

Note: The average packet throughput is calculated using 64, 128, 256, 512, 1024, 1280, and 1518 bytesEthernet frames.

11.5.2 Throughput (Bandwidth) Logging

As discussed earlier, the maximum throughput speed, or bandwidth, of a system is determined by thepurchased licensed speed key. This allows a service provider to provide a limited bandwidth and to bill forit accordingly.

Another billing method is to use Bandwidth Logging. This feature monitors bandwidth consumption overtime and the customer would be billed for the actual bandwidth consumed and not for a preset maximumbandwidth. As with the speed key, you will need to consult with DragonWave Inc. if you wish to make useof this option.

Note that Horizon Compact does not support Bandwidth Logging in the “secondary_hsb_1wire”redundancy mode, or the “secondary_x2” wireless link aggregation mode.

11.6 Adaptive Transmit Power Control (ATPC)

Adaptive Transmit Power Control (ATPC) allows a Horizon Compact system to adjust its transmit powerto compensate for far end signal loss caused by changes in atmospheric conditions e.g. heavy rain.ATPC maintains the RSL at -50 dB and adjusts the transmit power by up to 20dB as necessary in order tomaintain -50 dB during fade conditions.

RSL threshold levels that trigger power changes, the maximum power change allowed, and a hysteresisfactor are preset at values which optimize the operation of the Horizon Compact system. A fade factor of5dB/second can be handled.

The Horizon Compact system is able to discriminate between RSL levels that are reduced as a result ofinterference and those as a result of genuine path loss, so that ATPC is not invoked unnecessarily.

Some jurisdictions require the use of ATPC so that power levels are kept as low as possible whenwireless communication conditions are good. When ATPC is to be used, if it can be shown that themaximum power of the system would be used only on infrequent occasions, some jurisdictions will allow a

lower power level to be used in the calculations that determine interference criteria. This offers someadvantage to the installation. This lower power is termed the “coordinated power”. The DragonWaveATPC feature supports a coordinated power parameter.

ATPC and coordinated power are enabled or disabled by issuing the CLI command:

set atpc [on/off (atpc)] [on/off (coordinated power)] [0 -10 (coordinated power offset value)]

Example : set atpc on on 5 sets atpc on and coordinated power on with an offset of 5 dB

The current status of ATPC can be determined by using the CLI command get atpc status.

Note: ATPC and AAM cannot be enabled at the same time.

11.7 Horizon Compact Authentication

This feature is only necessary if you wish to restrict communication from a Horizon Compact unit to aspecific peer or to a group of Horizon Compact units. Authentication is generally used as a securitymeasure. It is not recommended to enable Authentication prior to alignment of the radios.

Authentication restricts a Horizon Compact unit from communicating with other Horizon Compact unitsunless the other units match an authentication string. There are three types of authentication:

1. No Authentication

2. Unique Authentication

3. Group Authentication

A new Horizon Compact system in line with the signal cannot authenticate and receive data if anotherHorizon Compact system is already authenticated. The system authenticates its peer(s) at an interval ofapproximately five seconds.

The Horizon Compact node does not accept data from other manufacturers’ systems.

11.8 Threshold Alarms

Horizon Compact provides Threshold Alarms to assist in managing the performance of the system.Threshold alarms are available for the parameters shown with default values in the following list:

1. RSL (Receive Signal Level) -70 dB for 10 seconds2. Bandwidth Utilization 100% for 10 seconds3. Dropped Frames 100% for 10 seconds4. Signal To Noise (SNR) * 0

With the exception of SNR, each Threshold Alarm has two associated parameters:

1. Threshold value

2. A time limit over which the Threshold value must be exceeded before the alarm isreported.

The combination of the value and the time limit is user defined. The proper combination of the twoparameters will prevent false alarms from occurring.

* For the SNR parameter, only the threshold level can be set, the time limit, or hysteresis, being a presetvalue.



11.9 Rapid Link Shutdown

It is often desirable to signal or detect network link issues in the quickest manner possible. This isespecially true when running Layer 2 redundancy protocols, such as Spanning Tree and Metro Ringprotocols. Signaling to the network is done by shutting down the Ethernet data port(s) connecting theHorizon Compact to the network. The Rapid Link Shutdown (RLS) feature provides this functionality.

Some situations that would result in Rapid Link Shutdown include:

Link outage. Should a power failure or a complete loss of link occur then Ethernet ports at bothends of the link can be shut down

Far-end Ethernet connection problems. If the remote unit data Ethernet port is disconnected ordisabled, the near-end unit will also shutdown it’s Ethernet port

Link quality problems. If the link quality (error rate) reaches user programmable thresholds theHorizon Compact Ethernet ports can be shut down

Horizon Compact configuration or hardware failure. If hard faults, such as a hardware failure,interrupt the link, both Horizon Compact Ethernet ports can be shut down.

Note that RLS is not compatible with the Horizon Compact redundancy option and should NOT beenabled when the redundancy option is employed.

11.10 Configuring the Time Source (SNTP)

Date and time information can be entered into the system using CLI command set date time[dd/mm/yyyy hh:mm:ss:ms] press Enter.

The date and time settings in Horizon Compact are not maintained if a power outage is experienced. Toensure that set system date and time are always accurate, the system can poll known time sources andupdate time information on an ongoing basis.

Up to five time sources can be configured, which can provide accurate time and date information to thesystem. Simple Network Time Protocol (sntp) is used. Either an Internet time source or an NTP server onyour network may be used.

Five time sources are configured by default (see Table 11-2). Each time source is indexed 1 to 5. Indices1 and 2 are from Industry Canada servers, 3 and 4 are from U.S. Navy servers and 5 is from a Swissserver. Any other time sources can be configured. The timing information is polled every 60 minutes.

11.11 Automatic Adaptive Modulation (AAM)

The two principal modulation schemes used on the Horizon Compact system are QPSK and QAM. QPSK(the lowest modulation scheme) is ideal for long distance, but has the lowest throughput capability.

Higher throughputs are achieved by using more complex modulation schemes e.g. 16-QAM, 32-QAM,64-QAM, 128-QAM, 256-QAM. The higher numbers indicate a progressively more complex scheme and ahigher bandwidth (throughput) capability e.g. 256-QAM is more complex than 128-QAM and provides ahigher throughput. More complex modulation schemes are susceptible to noise and thus require astronger signal for the demodulator to accurately decode the data stream. Consequently, the morecomplex the modulation scheme used, the shorter the distance limitation of the radio link.

If a system is using a given modulation scheme and weather conditions cause signal levels to deterioratebelow acceptable levels (risking a link failure), changing the modulation scheme to a less complex (lowerorder) scheme, will allow the link to remain functional, although the throughput will be lower, until weatherconditions improve. The modulation scheme can then be returned to the original scheme and thethroughput returned to normal levels.The Horizon Compact system can be configured to automatically change modulation schemes ifenvironmental conditions deteriorate to the point where a wireless link may otherwise fail. This feature iscalled Automatic Adaptive Modulation (AAM). Note that AAM cannot be invoked if RLS is enabled.

All radio bands available with the Horizon Compact support AAM.

Note: AAM and ATPC cannot be enabled at the same time.

Horizon Compact supports two AAM options – single stage and two stage adaptation.

11.11.1 Single Stage Adaptation

The current modulation scheme (determined by the configured system mode parameter) will switch to thelowest modulation scheme available (a number of system modes, which includes the modulation scheme,are available for any given radio band, see Section 6.3), if weather conditions cause the RSL to dropwithin 5 dB of threshold. By default, the transmit power will be increased to the maximum allowed for thatmodulation scheme (system mode), but the option exists to maintain the power level the same as thatoriginally configured regardless of modulation scheme.

The original modulation scheme will be restored once preset parameters indicate that conditions aresuitable for returning to the original modulation scheme (and return to the original bandwidth). The totaloutage time due to modulation downshift is approximately 50 to 100 mS on average, with upshift outagetime at approximately 75 mS.

11.11.2 Two Stage Adaptation

Horizon Compact has the option of a two stage reduction in modulation scheme. With AAM enabled, ifweather conditions cause the RSL to drop within 5 dB of threshold, the current modulation scheme(determined by the configured system mode parameter), will drop to a lower order, intermediate,modulation scheme (a lower order system mode). Consequently, throughput will be reduced.

The intermediate modulation scheme has a default value (system mode), which depends on the radioband configured in the system. However, the default system mode, and hence modulation scheme, canbe overridden if desired. A number of system modes, which includes the modulation scheme, areavailable for any given radio band, see Section 6.3.

If the RSL drops a further 5 dB then the modulation scheme will be reduced to the lowest order available,based on the radio band configured, and bandwidth will be further reduced.

By default, the transmit power will be increased to the maximum allowed for each modulation scheme(system mode), but the option exists to maintain the power level the same as that originally configuredregardless of modulation scheme.



As the RSL returns to normal values the system will automatically return to the original configured systemmode (modulation scheme).

The outage time due to modulation downshift is approximately 50 to 100 mS per step on average, withupshift outage time at approximately 75 mS per step.

11.12 Throughput Doubling

A single Horizon unit is capable of transmitting up to 400 Mbps. By employing two Horizon units,configured to operate in tandem, it is possible to double the overall throughput and thus achievethroughputs of up to 800 Mbps.

The actual throughput of a Horizon unit is limited by the channel spacing available for the radio bandbeing used. A single Horizon unit throughput of 400 Mbps can only be achieved with 56 MHz channelspacing, with lower rates being achieved at lower channel spacing values (e.g. 28 MHz).

There are two methods of throughput doubling. Option 1 is used to achieve up to 800 Mbps throughputand Option 2 is used where available channel spacing limits the throughput of a single unit to less than200 Mbps.

11.12.1 Option 1

For data rates higher than 400 Mbps, an Ethernet switch that supports link aggregation is required.Horizon can be configured as 2 units, each with their own separate antenna, or the Dual PolarizationRadio Mount (DPRM) can be used to mount two systems to a single antenna (see Figure 3-5). TheDPRM allows both systems to transmit/receive simultaneously, one with horizontal polarization and theother with vertical polarization, supporting load sharing or throughput doubling (up to 800 Mbps) (seeFigure 11-1)

Figure 11-1 DPRM and Throughput Doubling up to 800 Mbps

DragonWave Inc.74


11.12.2 Option 2 (WLAG x2)

Where the available radio bands for an installation have throughput limiting channel spacing, that result ina single Horizon unit not being able to provide the desired data rate for the link, Option 2, or WLAG x2Throughput Doubling, may be employed. The WLAG x2 option is achieved through a DragonWaveproprietary WLAG (Wireless Link Aggregation) mechanism.

The Dual Polarization Radio Mount (DPRM) can be used to mount two systems to a single antenna (seeFigure 3-5). The DPRM allows both systems to transmit/receive simultaneously, one with horizontalpolarization and the other with vertical polarization.

The Horizon unit which is to carry user traffic is configured as the Primary unit and the other (carriesmanagement) configured as the Secondary (see Figure 11-2).The data stream is fed into P1 of thePrimary unit and the built in packet switching mechanisms, including QoS, provides a balanced data feedto the Primary and Secondary radios which are running on two separate frequency channels. This allowsefficient bandwidth use between systems and enables the complete system to carry up to 400 Mbps.

In this configuration (both copper and optical interfaces), management activity is via port 1 (P1) of theSecondary Horizon. This means that the Secondary unit must be configured for in-band (port1)management. Management of the Primary unit is via the port 2 (P2) wired link between the two units, somanagement for the Primary is technically out-of-band, and so the Primary unit has to be configured forout-of-band (port2) management.

Note that traffic statistics reviewed on the Secondary unit are not valid. Traffic statistics need to bereviewed on the Primary unit.

The WLAG x2 option can only be used with system modes having a throughput capability of 200 Mbps orless and does not support RLS, AAM or ATPC. System modes and radio bands must be configuredidentically at each end of the link. See Volume 2 of this manual for more details.

Figure 11-2 DPRM and x2 Throughput Doubling up to 400 Mbps



11.13 Horizon Redundancy

The Horizon system can be configured for redundancy using two physical options. One option allows fortwo separate Horizon units, each with its own antenna, and connected to an Ethernet switch configuredwith a re-routing protocol. The switch is responsible for re-routing the data to the redundant stand-by unitwhen a failure occurs. This option is termed the “two wire” option.

The second option has two Horizon units mounted on a Power Switch Radio Mount (PSRM) with the datafeed from a single connection to a switch. Switching traffic to the redundant stand-by unit is determinedand performed by the Horizon Compact system and not the connected switch. This option is termed the“single wire” option.

The configuration steps for each option are different (see Volume 2 for more details).

Note that Rapid Link Shutdown (RLS) is not supported in either single or two-wire redundancyoptions.

11.13.1 BNC Connector

The BNC connector on the side of the Horizon Compact serves a dual purpose. It can be configured as asource for field strength measurements during antenna alignment, or configured to provide a redundancyswitch signal to a second Horizon Compact system mounted close by. For redundancy, the BNCconnectors on both units are interconnected with a coaxial cable. Note that for redundancy to work, youmust ensure that the field strength option for the BNC connector is turned off (set alignment off).

When the Horizon system is configured for redundancy, a DC signal is presented at the BNC connector ofthe unit normally carrying traffic. Since the BNC connectors on both units are interconnected, the DCsignal is passed to the stand-by unit. As long as the DC signal is present, then the stand-by radio is heldin a hot stand-by state. When the DC signal is removed (as a result of the unit normally carrying trafficfailing), then the stand-by radio becomes active, and takes over the traffic. After a redundancy switch,once the first system is able to return to carrying traffic, a manual switch is required, via a CLI command,to return the system to its original state.

11.13.2 Two Wire Option

The “two wire” option is so named because two separate data feeds are required; one to each Horizonsystem. One Horizon system is configured as the primary and the other as the secondary. Note that theterms “primary” and “secondary” relate solely to the internal functions of the units and has no relationshipto which radio is in stand-by or which is carrying traffic. Management has to be via Port 2, so eachHorizon will be configured for out-of-band management and have its Port 2 connected to the overlaymanagement network.

Data re-routing, between the Horizon systems, is dependant upon a connected Ethernet switch. Ethernetswitch settings are used to reroute the traffic from one Horizon unit to the other, when a failure occurs.Protocols such as RSTP, LACP and routing protocols are able to determine that the Horizon units haveswitched from active to stand-by units, or vice-versa, and will reroute the data traffic through the activelink.

NOTE: For clarity, the PonE power adapter and surge arrestor have been omitted from thediagram. Both the Port 1 and Port 2 Ethernet connections and the power feed via Port 1 must beprotected from transients.

Figure 11-3 Redundancy Connections – 2 wire option – copper interface



NOTE: For clarity, the required surge protector has been omitted from the diagram. Both the Ethernetmanagement feed to Port 2 and the power feed, via Port 2, must be protected from transients.

Figure 11-4 Redundancy Connections – 2 wire option – optical interface

A composite cable is available that includes two CAT5E cables and power feed wires and is terminated atthe Horizon end with the MIL style connector compatible with the Port 2 connection. One of the CAT5Ecables (grey) provides Ethernet connection to Port 2 for optional out-of-band management. The remainingCAT5E cable (blue) does not need to be terminated. A composite cable can be used to provide powerand optional out-of-band management to each of the Horizon units.

Where distances prevent the use of the composite cable due to power feed loss, a special “Y” feedadaptor cable is available that allows customer provided, heavier duty, wires to be spliced into the powerfeed connection. This latter configuration is shown in Figure 11-4.

DragonWave Inc.78


11.13.3 Single Wire Option with the PSRM

The “single wire” option is so named because only one data feed is required to be connected to the twointerconnected Horizon systems mounted on the PSRM.

The PSRM supports system redundancy by connecting two Horizon units to a single antenna. Only one ofthe radios of the mounted systems may operate at any one time. Both systems have the identicalpolarization, either both vertically or both horizontally polarized. One system is configured as the Primaryand the other as the Secondary. Note that the terms “primary” and “secondary” relate solely to the internalfunctions of the units and has no relationship to which radio is in stand-by or which is carrying traffic.

Port 1 of the primary unit carries the data feed, with Port 2 of both units interconnected. Port 1 of thesecondary unit handles management traffic. The secondary unit has to be configured for in-bandmanagement and the primary unit configured for out-of-band management.

Switching from the active unit to the stand-by unit is determined by the configuration of the HorizonCompact units and does not depend on connected Ethernet switches.

After a redundancy switch, once the first unit is able to return to carrying traffic, a manual switch isrequired, via a CLI command, to return traffic to the first unit.

NOTE: For clarity, the PonE power adapter and surge arrestor have been omitted from thediagrams. Both Port 1 Ethernet connections and the power feed via Port 1 must be protected fromtransients.

11.14 Ethernet Connectivity Fault Management

IEEE 802.1ag and ITU-T Y.1731 standards define mechanisms that provide Ethernet Connectivity FaultManagement (ECFM). ITU-T Y.1731 also defines performance monitoring mechanisms.

ECFM comprises a number of fault management mechanisms that work together to help administratorsdebug Ethernet networks. These are:

• connectivity check message (CCM)

• link trace message (LTM)

• loopback message (LBM)

• remote defect indication (RDI)

• alarm indication signal (AIS – supported by Y.1731 only)

The Y.1731 performance monitoring mechanisms include:

• frame loss measurement (LM)

• frame delay measurement (DM)

• throughput measurement

The Horizon Compact supports the CCM, LTM, LBM, and RDI mechanisms of 802.1ag and Y.1731mechanisms noted above. The AIS and performance monitoring mechanisms of Y.1731 are notsupported. However Horizon Compact will respond to DM messages.

Entering networking details of maintenance domains (MD), maintenance associations (MA), maintenanceassociation intermediate points (MIP) and maintenance end points (MEP), in various devices on anEthernet network, allows operators to trace fault conditions throughout that network. Configuration detailscan be found in Volume 2 of this manual.

11.15 Ethernet Operation Administration and Maintenance (EOAM)

EOAM is a protocol for installing, monitoring, and troubleshooting metro Ethernet networks. Horizon Compactsupports the EOAM features as defined in IEEE 802.3ah with the exception of the hardware loopback feature.EOAM is a relatively slow protocol with modest bandwidth requirements. The frame transmission rate is limitedto a maximum of 10 frames per second; therefore, the impact of OAM on normal operations is negligible. TheEOAM frames cannot propagate beyond a single hop within an Ethernet network.

Supported EOAM features include:

• Discovery

• Link Monitoring

• Remote failure indication

• Remote loopback (software only)


12.0 Horizon ManagementThe Horizon Compact system can be fully managed locally or remotely. Horizon Compact supports Telnetaccess, SNMP management and a Web interface accessible through the IP network. The entireCommand Line Interface (CLI) command set is available through Telnet. The entire list of systemparameters is available through SNMP access. The Web interface provides access to systemconfiguration and performance parameters. In-band and out-of-band management options are available.

12.1 In-band and Out-of-band Management

The Horizon Compact contains a dual NIC which has two 10/100/1000 Base-t Ethernet ports. These arelabelled Port 1 and Port 2. The system may be configured to use EITHER Port 1 (in-band), OR Port 2(out-of-band) for management traffic. Management traffic includes:

1. Telnet traffic and associated CLI commands

2. SNMP management

3. ping

4. FTP, used for configuration backup and restore and software upgrades.

All management functions that are available on Port 1 are also available on Port 2. Both ports may beconfigured to operate with or without management VLANs (see Section 11.2).

The key points to consider when choosing the network management configuration are as follows:

• Port 1 is always used for customer data traffic. It is not possible to send customerdata traffic over Port 2.

• Port 1 can be configured to support management traffic in addition to customer datatraffic. Use the CLI command set network management interface port1 then pressEnter. The default configuration is for management data traffic to be carried over Port1. Both ends of the link can be managed when Port 1 is set as the managementinterface.

• Port 2 can only be used for management. Port 2 does not carry any customer datatraffic. Port 2 is disabled by default and can be enabled by using the CLI commandset network management interface port2.

12.1.1 Management through Port 1 (in-band)

Port 1 is always used to carry customer data traffic and operates at rates of up to 400 Mbps over theradio link, from the local Horizon Compact system through to the far end Horizon Compact system.

Management is set to Port 1 (in-band) by default and management using Telnet, SNMP and Webinterface are supported. To enable in-band management on a system that has been set to out-of-bandmanagement (Port 2), use the CLI command set network management interface port1 then pressEnter.

When the network management interface is set to "port1" all management traffic must arrive on Port 1, orit will be ignored by the system. Configuration and management of the Horizon Compact system can beaccomplished through a Telnet, or SSH, session, and although the Telnet session is intermixed with usertraffic, the Telnet session occupies very little bandwidth (in the order of kbps) and therefore has almost noeffect on user traffic throughput.

A Telnet, or SSH, session can be established through one Horizon Compact system, over the radio link tothe far end Horizon Compact system, allowing management of both ends of the link.

DragonWave Inc.82


Management of the Horizon Compact system can also be performed through a VLAN using 802.1QVLAN tagging. Management through VLAN offers increased access security. Refer to Section 11.2 formore information.

12.1.2 Management through Port 2 (out-of-band)

Port 2 is available for out-of-band management purposes only. It does not carry customer data traffic. Ithas been designed to be used in conjunction with a management overlay network that is separate fromthe customer data network. The management overlay network is typically extended back to the NetworkOperations Center.

To select out-of-band management use the CLI command set network management interface port2and press Enter. This allows management of the near end unit only. To gain access to the far end unituse the CLI command set network management interface port2 extended and press Enter. Note: Withthis “extended” command, if the far end system is also configured for “port2 extended” and an Ethernetconnection is present on Port 2 of the far end system, a network loop may be created.

Port 2 supports management of the Horizon Compact system through Telnet sessions, SNMP and theWeb interface. When the management interface has been set to "port2", all management traffic mustarrive on Port 2, otherwise it is ignored by the system. Customer data traffic continues to be carried overPort 1.

12.2 Telnet Access

Once correctly configured, the Horizon Compact is accessible through a Telnet session using SuperUser, NOC and Admin level user accounts. Refer to Appendix A for details of CLI commands. TheHorizon Compact system can be completely configured, tested and managed through a Telnet session.The Telnet function is enabled by default but can be disabled within the Horizon Compact system. Usethe CLI command set telnet [on/off] to enable or disable Telnet access.

12.3 Secure Shell Access Security

Telnet sessions over a network, such as the Internet, are not secure. User names and passwords, as wellas commands and system responses, are transmitted in clear text during a Telnet session. A secure shell(SSH) protocol can be enabled in the Horizon Compact system to ensure that access to the units isrestricted to authorized clients. Horizon Compact uses the Secure Shell SSH2 server programme tocreate the secure environment for Telnet sessions. SSH2 is a recognised industry standard, encrypting,security programme. When enabled, SSH encrypts the entire Telnet session, including all usernames,passwords, commands and responses from the system. SSH also verifies that you are talking to thedesired server by means of an authentication process using a “fingerprint”. The “fingerprint” is a uniqueidentifier found only on the desired server.

Enable/disable SSH by issuing the CLI command set ssh server [on/off] then press Enter.

The server “fingerprint” can be returned by issuing the CLI command get ssh server fingerprint thenpress Enter.

A Secure Shell client programme needs to be installed on any computer which is to be used to manage aHorizon Compact system with SSH enabled. A free SSH client programme (PuTTY) is available on theWeb.

Note that both SSH and Telnet can be enabled at the same time. To ensure security, once SSH has beenenabled, disable Telnet.

12.4 Supported SNMP VersionsDragonWave Horizon Compact systems support three versions of SNMP.

Version 1 (SNMP v1) is the initial implementation of SNMP.

Version 2 (SNMPv2c) is the second release of SNMP, which has additions and enhancements todata types, counter size and protocol operations.

Version 3 (SNMPv3) is the most recent version of SNMP. The functionality of SNMPv1 andSNMPv2c remain intact, but SNMPv3 has significant enhancements to administration andsecurity.

SNMPv3 is an interoperable standards-based protocol that provides secure access to devices byauthenticating and encrypting packets over the network. The security features provided in SNMPv3 areas follows:

Message integrity Authentication Encryption

SNMP configuration is covered in detail in Volume 2.

12.6 Horizon Compact SSL Web Server

The Horizon Compact Web server can be configured for Secure Sockets Layer (SSL). The Web servermay be configured to operate in standard mode or in SSL mode. The Horizon Compact SSL Web serveris HTTP 1.0/1.1 compliant, features full support of HTML 2.0, 3.2, 4.0 and supports SSL 3.0.

Secure Sockets Layer, SSL, is the standard security technology for creating an encrypted link between aWeb server and a browser. This link ensures that all data passed between the Web server and browserremain private and integral. In order to be able to generate an SSL link, a Web server requires an SSLCertificate.

In order to invoke SSL on the Horizon Compact Web server, an SSL certificate must be generated on theHorizon Compact. Horizon Compact uses an embedded SSL Web server from Allegro SoftwareDevelopment Corporation. Once generated, the certificate may be held as a private certificate or it maybe registered with a Trusted Certificate Authority such as:

• Allegro Software Development Corporation

• Microsoft Root Authority

• Thawte Server

• GTE Cybertrust Root

• VeriSign RSA Secure Server

SSL access can be enabled on a per-user group basis. SSL access can be invoked for the Super User,for all NOC accounts, for all Admin accounts, or any combination of the three. Once SSL access hasbeen enabled for the user group then all members of that user group must use SSL to connect to theHorizon Compact Web browser. Even if SSL access is not required for the user group, those users mayaccess the Horizon Compact Web browser through HTTPS (SSL) as a security measure.

12.6.1 Generating a Certificate on Horizon Compact

In order to generate an SSL certificate on Horizon Compact, the user must be logged in as either a NOCor Super User access level. The SSL certificate is tied to the Horizon Compact IP address. If the HorizonCompact IP address is changed, then the SSL certificate should be regenerated. Otherwise the browserSSL session will allow access but it will report that the certificate is invalid. In this situation, it is the

DragonWave Inc.86


browser user's responsibility to verify that the proper Horizon Compact is being accessed and that theinvalid certificate is due to an IP address change.

12.7 Event and Performance Logging

The Horizon Compact system supports two logs, the Events Log and the Performance Log. Each can beused to track the behaviour of the system over time. In addition, a “Syslog” feature (see 12.7.3) can beinvoked that sends information stored in the event and performance logs to a remote syslog server, forfurther analysis. The Events Log, Performance Log and the Syslog features are independent of oneanother, allowing all or either one to be functional without affecting the other.

12.7.1 Events Log

The Events Log is invoked or disabled by issuing the CLI command set logging [on/off]. This log recordsalarm, reset, configuration changes and user login events. Approximately 17,500 events can be capturedby the Events log. Once the log is full the oldest entries are overwritten. Use the CLI command get logentries and press Enter, to display log entries. Use Ctrl C to abort the listing.

12.7.2 Performance Log

Issuing the CLI command set performance logging [on/off] enables or disables the Performance Log.This log collects system performance information at time intervals that are configured using the CLIcommand set performance log interval [hh:mm:ss].

Use the CLI command get performance log and press Enter, to display a list of Performance Log entries(SNR, Eb/No, RSL, Temperature, Average BW, Peak BW). Use Ctrl C to abort the listing.

Between 6000 and 8000 entries can be logged before the Performance Log memory is full. Once thememory is full, new entries will overwrite the oldest entries. The following table assumes that an averageof 7000 entries will occur before memory overflow. If the memory accepts more entries, then the logduration before overflow will be extended.

12.7.3 Syslog Feature

The Syslog feature allows an operator to forward event logs and performance logs to a remote syslogserver (IP address required). This feature can only be invoked using CLI commands (not supported bySNMP or the Web GUI interface).

To configure you must set the IP address of the syslog server to which you wish the logs to be sent andthen set syslog forwarding on. Use the CLI commands set syslog forwarding host <ip address> andset syslog forwarding [on|off] .

Use the CLI commands get syslog forwarding status and get syslog forwarding host to viewconfigured settings.

Logging Interval Log Duration

15 secs (minimum) ~ 29 hours

1 minute ~ 116 hours (~ 4.8 days)

15 minutes (default) ~ 73 days (~ 2.4 months)

1 hour ~ 292 days (~ 9.7 months)

24 hours (maximum) 7000 days (~ 19.2 years)



12.8 Radio LoopbackHorizon provides a radio loopback facility for analysis of transmit or receive path issues. Invoking a radioloopback is service affecting and will stop all data transfer. There are two options:

Straight radio loopback - Ethernet traffic is not looped back to the network, Ethernet traffic isdiscarded and the RF portion of the Horizon unit is placed in loopback (see ).

Radio loopback plus network loopback – Ethernet traffic and the radio are placed in loopback

During the loopback, if the modem transmitter loss of sync alarm is not active, then both the transmitterand receiver of the Horizon unit under test are functioning correctly. A user configurable time limit can beapplied to the loopback feature (default is 30 seconds). Once the time limit has expired the loopback willbe automatically removed.

Note that the far end transmitter should be muted when analysing the near end system using the radioloopback feature. Use the CLI command set radio transmitter state [on|off] [yyy] to mute and un-mutethe far end radio. When muting, the [yyy] parameter is the number of seconds that the radio will remainmuted before automatically turning back on. If no timing parameter is entered, then the radio will remainmuted indefinitely until a set radio transmitter on command is issued.

The radio loopback is invoked or disabled by issuing the CLI command set radio loopback [on/off][time][network].

13.0 Configuration Backup and RestoreHorizon Compact provides a backup and restore facility for system configuration data and user accountdata. The backup and restore uses an FTP server to transfer files. It is recommended to have an FTPserver at your network management site for use with the Horizon Compact backup and restore facilities.Note that the Super User or a noc user level can perform backup and restore functions.

13.1 System Configuration Backup

The Horizon Compact system configuration can be saved to an FTP server. All system configurationparameters are backed up, allowing the exact configuration to be replicated.

Use the CLI command: save config ftp:<filename> press Enter

where <filename> is the name of the file to be created on the FTP server in the format<filename.config>. Note that the file suffix must be “.config”. Follow the prompts.

Note that the above command will save the file in the root directory of the ftp server. Adding the pathinformation to the file name will allow you to save it in a specific directory on the ftp server.

13.2 System Configuration Restore

The Horizon Compact system configuration can be retrieved from the FTP server on which it was backedup. All system configuration parameters are restored, allowing the exact configuration to be replicated.

Use the CLI command: copy ftp: <filename> press Enter

where <filename> is the name of the file to be created on the FTP server in the format<filename.config>. Note that the file suffix must be “.config”. Follow the prompts.

Note that the above command will retrieve the file from the root directory of the ftp server. Adding the pathinformation to the file name will allow you to retrieve it from a specific directory on the ftp server.

13.3 User Account Configuration Backup

The Horizon Compact system user account configuration can be saved to an FTP server. All useraccount parameters are backed up, allowing the exact configuration to be replicated.

Use the CLI command: save users ftp:<filename> press Enter

where <filename> is the name of the file to be created on the FTP server. Follow the prompts.

Note that the above command will save the file in the root directory of the ftp server. Adding the pathinformation to the file name will allow you to save it in a specific directory on the ftp server.

14.0 Software UpgradesFrom time to time new software loads are made available that may add new features to the HorizonCompact system. You can download new software remotely using File Transfer Protocol (FTP). Newmodem software and frequency files may also be released. Note that whereas a new software upgrademay function with an existing frequency file, an upgraded frequency file may not function with an oldersoftware release. Because of this, it is wise to always upgrade software before upgrading to a newfrequency file.

Use the Command Line Interface (CLI) via Telnet and invoke the FTP with either a local FTP server thatis on the same network as the Horizon Compact system, or use the DragonWave FTP server siteavailable through the Internet. The Horizon Compact can interact with the most popular FTP servers on avariety of operating systems. Anonymous FTP, as well as a user–supplied username and password aresupported. As an alternative, DragonWave Merlin may be used.

14.1 Upgrade Path

Depending on the software load currently running in the system, there may be a requirement to load morerecent versions before being able to load the latest software version successfully. Frequency filedownloads and modem omni file downloads will also be required to enable all new features. Certainexisting features may also need to be disabled before software downloads are performed in order forthem to be successfully upgraded.

Use FTP protocol to download all files (see Section 14.2). If using Merlin, use the FTP Software Upgradeoption. Do NOT use the MAC (layer 2) Protocol option.

Referring to the steps shown in Table 14-1, use the following procedure:

• For systems currently loaded with software releases prior to omni_1.01.00, start at step 1.

• For systems currently loaded with software release omni_1.01.00 start at step 4.

• For systems currently loaded with software release omni_1.01.32 start at step 6.

STEP PROCEDURE1 download omni_1.01.00 first

2 reset system

3 save mib

4 download omni_1.01.32

5 reset system

6 ensure that AAM is disabled at both ends of the link (set aam off)

7 download omni_1.02.00

8 download modem omni file mdmOmni_1.02.00

9 reset system

10 download frequency file 2.xx.xx (if required)

11 reset system

12 repeat steps at other end of link

13 enable AAM at both ends of the link if required (set aam on)

Table 14-1 Software Upgrade Path

Notes: omni_1.02.00 will continue to work with existing 1.xx.xx frequency files. However, you cannotdownload 1.xx.xx frequency files if omni_1.02.00 is already loaded.

When release 2.xx.xx frequency file is installed, it supersedes the 1.xx.xx frequency files, if they exist inthe system.

For AAM to work with omni_1.02.00, release 2.xx.xx frequency file must be installed.

DragonWave Inc.92


14.2 Single System

Log into the system via Telnet and use the CLI command copy ftp: <filename> and press Enter. Where<filename> is the name of the software load file in the format omni_x.y.z.hex and includes any pathinformation.

You will be prompted for the IP address of the FTP server. The FTP server will then prompt you for username and password.

Once the download is complete you will need to use the CLI command save mib and press Enter.The new software is now saved in non volatile memory, but not yet in use.

Note that traffic is not affected during the software download process.

To make the new software load active requires the system to be reset. This is traffic affecting.

To activate the new software load use the CLI command reset system and press Enter. Then pressY. The system will reset and load the new software.

14.3 Multiple Systems

DragonWave Merlin software can be used to upgrade several systems in a network simultaneously usingFTP. If the Horizon Compact system has the Enhanced Security Access option, the CLI command set apaccess on must be invoked before multiple upgrades using Merlin will work.

The number of systems capable of being upgraded simultaneously is limited only by the number of activeFTP sessions allowed by the on-net FTP server.
