Overview

High AvailabilityThe following features contribute to the ED-48000B high-availability design:

◆ Redundant, hot-swappable components

◆ Redundant power supply and blower assembly subsystems

◆ Enhanced data integrity on all data paths

◆ Fabric Shortest Path First (FSPF) rerouting around failed links

◆ Integration with Simple Network Management Protocol (SNMP) managers

◆ Automatic control processor failover

◆ Nondisruptive “hot” software code loads and activation

◆ Easy configuration, save, and restore

◆ Hot-swappable World Wide Name (WWN) card

The high-availability software architecture of the ED-48000B provides a common framework for all applications that reside on the system, allowing global and local states to be maintained enough to manage any component failure. High-availability elements consist of the High Availability Manager, the heartbeat, the fault/health framework, the replicated database, initialization, and software upgrade.

The High Availability Manager controls access to the standby control processor, facilitates software upgrades, prevents extraneous switchover activity, closes and flushes streams as needed, provides flow control and message buffering, and supports a centralized active and standby state.


1Overview

ReliabilityThe ED-48000B uses the following error detection and correction mechanisms to ensure the reliability of all data inside the chassis:

◆ All data inside the switch protected by the Error Detection and Correction mechanism, which checks for encoder errors and fault isolation (EDFI), such as cyclic redundancy checking (CRC), parity checking, checksum, and illegal address checking.

◆ Power-on self-test (POST).

◆ Dual control processors that enable hot, nondisruptive fast firmware upgrades.

◆ Each control processor contains two serial ports and one Ethernet port. Offline control processor diagnostics and remote diagnostics simplify troubleshooting. The standby control processor continuously runs diagnostics to ensure it is operational, should a failover be necessary.

◆ Inter-IC (I2C) monitoring and control.

Reliability 1-9

1-10

Overview

ServiceabilityThe ED-48000B provides the following features to enhance and ensure serviceability:

◆ Modular design with hot-swappable components

◆ Redundant flash memory that stores two firmware images per control processor

◆ Extensive diagnostics and status reporting, along with a serial port to support an external, country-specific modem for remote diagnostics and status monitoring

◆ Nonvolatile random-access memory (NVRAM), containing the OEM serial number, EMC serial number, revision information, and part number information

◆ Background health-check daemon

◆ Memory scrubber, self test, and bus ping to determine if a bus is not functioning

◆ Watchdog timers

◆ Status LEDs

◆ Predictive diagnostics analysis through Fabric Watch

◆ SNMP integration with higher-layer managers


1Overview

Software FeaturesThe ED-48000B is supported by . The FOS allows any Fibre Channel-compliant device to attach to the switches as long as it conforms to the device login, name service, and related Fibre Channel standards. Each operating environment requires that a Fibre Channel host bus adapter (HBA) be available with a standards-compliant driver for proper interface to the fabric.

FOS consists of a set of embedded applications running on top of an embedded real-time Linux operating system kernel. These applications are the Name Server, alias server, Simple Network Management Protocol (SNMP) agent, and several tasks to manage address assignment, routing, link initialization, fabric initialization, link shutdown, switch shutdown, and the user interface.

Security Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure remote login and other secure network services over an insecure network.

Web Tools management is available through a secure browser using Secure Sockets Layer (SSL). The SSL security protocol provides data encryption, server authentication, message integrity, and optional client authentication for a TCP/IP connection. Because SSL is built into all major browsers and Web servers, installing a digital certificate turns on the SSL capabilities.

NetworkManageability

The ED-48000B is managed as a single element and appears as a single element to a Network Management System (NMS). The director responds to its own IP address and appears as a separate entity to the Telnet protocol and SNMP.

All management interfaces, such as Telnet, Web Tools, the Fabric Access Layer API, and Management Server, support a “port N within blade M” naming scheme.

When SNMP devices send SNMP messages to a management console running SAN management software, the information is stored in a management information base (MIB). Fabric OS v5.0 supports the latest Fibre Alliance Fibre Channel Management (FCMGMT) and Storage Management Initiative (SMI) MIBs, which allow common information necessary for management software to provide information to a SAN administrator. Refer to the Fabric OS MIB Reference Manual for additional MIB information.

Overview

Port NumberingExcept for the following cases, the area ID is equal the port number:

◆ When you perform a port swap operation

◆ When you enable Extended Edge PID mode on the director. For more information on Extended Edge PID mode, refer to the Fabric OS Administrator’s Guide.

The ED-48000B uses the following port numbering schemes:

◆ For the FC4-16 port blade, ports are numbered from 0 through 15 from bottom to top.

◆ For the FC4-32 port blade, ports are numbered from 0 through 15 from bottom to top on the left set of ports and 16 through 31 from bottom to top on the right set of ports.

Slots are numbered 1 through 10, from left to right when facing the portside of the director.

Site Planning and Safety Guidelines

WARNING

A fully populated ED-48000B (256 ports) weighs approximately 216 lbs (96 kg) and requires a minimum of two people and a hydraulic or assisted lift to install it.

Do not use any of the bays (such as the power supply or blower assembly bays) for leverage.To ensure adequate cooling, install the chassis with the nonport side facing the air-intake aisle. This prevents the blowers from pulling in heated exhaust air.

If the switch is installed in a cabinet, ensure that the cabinet is balanced and secured mechanically and that the removal and installation procedure will not compromise cabinet stability.

The following steps are required to ensure correct installation and operation:

1. Consult the Connectrix EC-1500 Cabinet Setup and Installation Manual for site planning information related to the cabinet.

2. Plan to install the ED-48000B with the nonport side facing the air-intake aisle.

3. Plan for cable management before installing the chassis (refer to Managing Cables on page 2-10).

Cables can be managed in a variety of ways, such as by routing cables below the chassis, to either side of the chassis, through cable channels on the sides of the cabinet, or by using patch panels.

4. Ensure that the blowers in the ED-48000B have access to a total minimum air flow of 350 cubic feet per minute (595 cubic meters per hour).

5. Ensure that the air-intake and exhaust vents have a minimum of 2 inches of airspace.

6. Ensure that the air temperature on the air intake side is less than 40 degrees Celsius (104 degrees Farenheit) during operation.

Providing Power to the ED-48000B

If a modem is to be used with the ED-48000B, it needs to be connected prior to powering on the switch. To install a modem, refer to Chapter 7, Setting Up and Installing Modems.

To provide power to the ED-48000B:

1. Verify that the ON/OFF switch for each port blade and CP blade is in the ON position (see Figure 4-2 on page 4-8).

2. Verify that the AC switch covers are installed over the AC switches. These clear plastic covers fit over the AC switches with their edges tucked underneath the outlet covers; they prevent the AC switches from being powered on or off accidentally (see Figure 2-1).

3. Connect the AC power cord retainers to the chassis: Orient a retainer against the AC panel as shown in Figure 2-1, place the retainer tabs under the two jack screws on either side of the power receptacle; and tighten the screws. Repeat for the other retainer (note that the power-cord retainers are oriented in the same direction as the power receptacles).

4. Loosen the clamping screw on each retainer, insert the power cords through the retainers into the power receptacles on the ED-48000B, and tighten the clamping screws. The power cords are designed to bend to the left, so each should route to an opposite side of the chassis.

5. Ensure that the power cord has a minimum service loop of 6 inches available at the connection to the switch and is routed so that it is not exposed to stress.

6. Connect the power cords to the PDUs within the Connectrix cabinet.

7. Flip both AC power switches to 1. The AC power switches light up green when switched on and power is supplied.

The ED-48000B automatically performs a power on self-test (POST) by default each time it is powered on. POST takes approximately 10 minutes and is complete when indicator light activity returns to the standard state. For information about LED patterns, refer to Chapter 4, Monitor System Components.

CAUTION!To prevent a potential IP address conflict, do not connect the ED-48000B to the network until the IP addresses are configured. Refer to Chapter 3, Initial Configuration Parameters for additional information. Allow the ED-48000B to run for 10 minutes (minimum) to complete POST after powering on before you power off.

Establishing a Serial ConnectionInitial communication to a ED-48000B switch requires a serial connection.

To establish a serial connection and log in to the director:

1. Verify that the ED-48000B is powered on and that POST is complete by verifying that all power LED indicators on the port blades and CP4 blades are displaying a steady green light.

2. Use the serial cable provided with the ED-48000B to connect the console port on the active CP4 blade to a computer workstation.

The console port is the second serial port from the top of the CP4 blade; the active CP4 blade is indicated by an illuminated (blue) LED. The “Active CP” LED in the standby CP blade should be off (not illuminated).

The console port is intended primarily for use during the initial setting of the IP address and for service purposes. If necessary, the adapter on the serial cable can be removed to allow for an RJ-45 serial connection.

3. Access the director using a terminal emulator application (such as HyperTerminal on Windows 95, Windows 2000, or Windows NT, or TERM in a UNIX environment).

4. Disable any serial communication programs running on the workstation (such as synchronization programs).

5. Open the terminal emulator application and configure as follows:

For most MS Windows systems:

Bits per second: 9600Databits: 8Parity: NoneStop bits: 1Flow control: None

For most UNIX systems, type the following string at the prompt:

tip /dev/ttyb -9600

When the terminal emulator application stops reporting information, press ENTER. The following login prompt appears:

CP0 Console Login:



6. Log in to the ED-48000B as admin. The default password is “password”. At the initial login, you are prompted to enter new admin and user passwords.

7. Modify passwords, if desired. Passwords can be 8 to 40 characters long. They must begin with an alphabetic character. They can include numeric characters, the dot (.), and the underscore ( _ ). Passwords are case-sensitive, and they are not displayed when you enter them on the command line. To skip modifying the password, press CTRL-C. For more information on passwords, refer to the Fabric OS Administrator’s Guide.

Fabric OS (swDir)

swDir login: adminPassword:Please change your passwords now.Use Control-C to exit or press 'Enter' key to proceed.

Managing CablesThe new cable management tray introduced in the ED-48000B allows for simpler cable management. The new tray allows additional space between the chassis and shelf and can be installed without service disruption.

The ED-48000B cables can be managed in a variety of ways, including the following:

◆ Routed down through the cable management tray

◆ Routed out either side of the chassis

◆ Cable channels on the sides of the cabinet

◆ Patch panels

Two items are provided to assist with cable management:

Cable Management Tray

The cable management tray is attached to the chassis under the chassis door, and can be used to route the power cables and other cables down below the chassis or out the sides of the chassis (see Figure 2-2 on page 2-11).

Cable Guides (Pillars)

Cable guides (pillars) are provided with the ED-48000B, and can be used to organize the port cables into logical groups, such as according to port quads (sets of four neighboring ports). The cable guides do not attach to the chassis (see Figure 2-3).

Cable pillars are not supported when using the FC4-32 port blades because the cable count is too dense, leaving no room for the cable pillars. Instead, you should use hook and loop tabs to group cables for the FC4-32 port blades.

Figure 2-3 Cable Guides (Pillars) Used to Group Cables

The cable guides serve to keep the cables evenly spaced and to hold them away from the port blades, making blade replacement easier and preventing the cables from bending to less than the minimum bend radius.

CAUTION!Do not route the cables in front of the air exhaust vent, which is located at the top of the port side of the chassis.

Arrange the cables so that the minimum bend radius is not exceeded; for a 50-micron cable, the minimum bend radius is 2 inches under full tensile load and 1.2 inches with no tensile load.

Tie wraps are not recommended for optical cables because they are easily overtightened and can break the optical cables.



To keep LEDs visible and make it easy to replace components, route cables down in front of the blades, not across adjacent blades or in front of the power supplies. Figure 2-2 on page 2-11 provides an example in which cables for each blade are routed in front of that blade and are out of the way of other components.

Leave at least 1 meter of slack for each fiber-optic cable. This provides room to remove and replace the port blade, allows for inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.

Use the cable guides provided with the ED-48000B to group the cables. These guides help to keep individual ports accessible by keeping the cables evenly spaced. If ISL Trunking is in use, grouping the cables by trunking group is recommended. The ports are color-coded to indicate which ports can be used in the same ISL Trunking group: four ports marked with solid black ovals alternate with four ports marked with oval outlines.

ISL Trunking is an optional Fabric OS feature that enables distribution of traffic over the combined bandwidth of up to eight ISLs between two directly adjacent switches, while preserving in-order delivery.

A minimum length is required for cables that connect the ED-48000B ports to device ports, as described in Table 2-2.

Initial Configuration Parameters

The ED-48000B must be configured before it is connected to the fabric, and all of the configuration commands must be entered through the active CP blade. The ED-48000B configuration includes the following parameters:

◆ IP address and subnet mask for the chassis

◆ IP addresses, host names, subnet masks, and gateway addresses for both CP blades

◆ Director name

◆ Domain ID for the director (optional)

◆ WWN for the director

The director WWN is initially set by the factory to match the license ID (which is based on the chassis serial number). The WWN can be changed but the license ID cannot be modified.

The configuration information is automatically mirrored to the standby CP blade—allowing the most current configuration to remain available even if the active CP blade fails. The configuration information for the switch is stored in the WWN card and the flash memory of the CP blades. The configuration can be backed up to a workstation (uploaded) and then downloaded to the active CP blade if necessary.

The basic steps required for the initial configuration are:

1. Log in to the director.

2. Set up IP addresses.

3. Establish an Ethernet connection (optional).

4. Specify a director name.

5. Specify a domain ID for the director.

6. Verify that the PID mode matches the fabric and connect the director to the fabric.

7. Enable software licenses as necessary.

8. Back up the configuration.


3Initial Configuration Parameters

Configure IP Addresses for the ED-48000BThe ED-48000B director requires three IP addresses, which are configured using the ipAddrSet command. IP addresses are required for both CP blades (CP0 and CP1) and for the single logical switch (shown as SWITCH under the ipAddrShow command) in the ED-48000B director.

The IP and gateway addresses must reside on the same subnet. The same gateway address must be used for both CP blades (these gateway addresses are referenced for the IP addresses).

Resetting an IP address while the ED-48000B has active IP traffic such as Fabric Manager, Fabric Watch, SNMP, or other applications can cause traffic to be interrupted or stopped. Changing the IP address causes a domain address format RSCN to be issued.

The addresses 10.0.0.0 through 10.0.0.255 are reserved and used internally by the switch. External IPs cannot use these addresses either.

The default IP addresses and host names for the ED-48000B are as follows:

◆ 10.77.77.75 / CP0 (the CP blade in slot 5 at the time of configuration)

◆ 10.77.77.74 / CP1 (the CP blade in slot 6 at the time of configuration)

Configuration changes can only be made through the active CP blade. If the CP blade in slot 5 is not the active CP blade, disconnect the serial cable and connect it to the CP blade in slot 6; then, log in as admin.

Follow these steps to configure the IP addresses for both CP blades (from the active CP blade):

1. Log in to the active CP as admin using the serial cable connection.

2. Set up the director IP address by entering the ipaddrset -sw 0 command:

swDir:admin> ipAddrSet -sw 0

Configure IP Addresses for the ED-48000B 3-3

Enter the requested information at the prompts. Unlike the ED-12000B or ED-24000B, the only valid configuration for the ED-48000B is as a single domain (single logical switch), so you only need to specify the -sw 0 IP address. There is no -sw 1 in the ED-48000B.

3. Set up the CP0 IP address by entering the ipaddrset -cp 0 command:

swDir:admin> ipAddrSet -cp 0

Enter the requested information at the prompts.

4. Set up the CP1 IP address by entering the ipaddrset -cp 1 command:

swDir:admin> ipAddrSet -cp 1

Enter the requested information at the prompts.

Following is a sample IP configuration:

Establish an Ethernet ConnectionAfter using a serial connection to configure the IP addresses for the ED-48000B (refer to Configure IP Addresses for the ED-48000B on page 3-3), you can connect the active CP blade to the local area network (LAN) if desired.

Connecting the CP blades to a private network/VLAN is recommended.

By establishing an Ethernet connection, you can complete the ED-48000B configuration using either the serial session, telnet, or our graphical management interfaces: Web Tools, and Fabric Manager. Make sure that the ED-48000B is not modified from other connections at the same time.

To establish an Ethernet connection to the ED-48000B:

1. Remove the shipping plug from the Ethernet port on the active CP blade.

2. Insert one end of an Ethernet cable into the Ethernet port.

3. Connect the other end to an Ethernet 10/100 Base-T LAN.

The ED-48000B can now be accessed by remote connection using any of the available management tools, such as Telnet, Web Tools, or Fabric Manager.

4. To complete any additional ED-48000B configuration procedures through a Telnet session, log in to the switch by Telnet, using the admin login. The default password is “password”.



Customize a Switch NameThe switch name of the ED-48000B director can be up to 15 characters long; can include alphabetic, numeric, and underscore characters; and must begin with an alphabetic character. The default name for the ED-48000B is “swDir”.

Changing the name causes a domain address format RSCN to be issued.

To customize the name, follow these steps:

1. Type switchName followed by the new name in quotes.

swDir:admin> switchName "swDirector5"Committing configuration...Done.swDirector5:admin>

2. Record the new name for future reference.

Customize a Switch Name 3-7

3-8


Set the Domain IDEach switch in the fabric must have a unique Domain ID. The Domain ID can be set by typing the configure command. You can also allow the Domain ID to be automatically set. The default Domain ID for the ED-48000B is “1”.

To set the Domain ID:

1. Type fabricShow to determine the current Domain IDs available.

2. Type switchDisable to disable the ED-48000B.

3. Type configure.

4. Type y at the “Fabric parameters” prompt:

Fabric parameters (yes, y, no, n): [no] y

5. Enter a unique Domain ID:

Domain: (1..239) [1] 3

6. Complete the remaining prompts or press CTRL+D to accept the other settings and exit.

7. Type switchEnable to reenable the ED-48000B.



Verify the PID Mode and Connect to the FabricBefore connecting the ED-48000B to the fabric, verify the port identifier (PID) mode on the switch matches the other switches in the fabric. This parameter must be set identically on all switches in the fabric. This parameter is set using the configure command. For more information on PID mode, refer to the Fabric OS Administrator’s Guide.

To connect the ED-48000B to the fabric, follow these steps:

1. Add SFP transceivers and cables to the Fibre Channel ports, as required.

The ports are color-coded to indicate which ones can be used in the same port group for trunking; trunking port groups can be up to eight ports. Trunk groups are displayed by shaded or nonshaded ports. The ports and cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the “ISL Trunking” section of the Fabric OS Administrator’s Guide.

2. Position one of the SFP transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks.

Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented. For instructions that are specific to the transceiver model, refer to the transceiver manufacturer’s documentation.

3. Position a cable so that the key (the ridge on one side of the cable connector) is aligned with the slot in the transceiver; then, insert into the transceiver until the latching mechanism clicks.

Cables are keyed so that they can only be inserted with the correct orientation. If a cable does not slide in easily, ensure that it is correctly oriented.

4. Repeat step 1 through step 3 for the remaining ports.

5. Organize the cables as required. For recommendations regarding cable management, refer to the Managing Cables on page 2-10.

6. Verify switch and port status using the switchShow command. The switchShow command provides detailed information about the switch.

7. Verify fabric connectivity using the fabricShow command at the prompt. The fabricShow command provides general information about the fabric.



Enable Software LicensesThe ED-48000B is shipped with licenses for Web Tools and Zoning factory installed. Licenses for other optional features are available by contacting your EMC account representative. To determine which licenses are currently enabled, use the licenseShow command.

swDir:admin> licenseshowAAbbccDDeeFFeeGG: Web license Zoning license Extended Fabric license Fabric Watch license Performance Monitor license Trunking license Security license

In the previous example, the license key is AAbbccDDeeFFeeGG. Make sure you keep a hardcopy of your license key in a secure location for emergency reference.

The 64-bit chassis ID is required to obtain and activate licenses for the ED-48000B. The chassis ID is available through the licenseIdShow command.

Both the licenseShow and licenseIdShow commands must be typed through the active CP blade.

For information about activating licenses, refer to the Fabric OS Administrator’s Guide.

Enable Software Licenses 3-11

3-12


Back Up the ConfigurationYou should save all key configuration data for the ED-48000B—including license key information—and upload it to a host for emergency reference. Routine backups of the configuration are recommended to ensure the current configuration is available if needed.

After all zoning configurations and other changes are complete, back up the configuration by typing configUpload at the prompt. The configUpload command uploads the ED-48000B configuration to the server so that it is available for downloading to a replacement switch, if necessary.

An easy way to backup configuration information is to enable logging on your telnet session and run the following commands and save the output in a file on a secure host.

Once you enable logging, run the following commands:

◆ configShow

◆ ipaddrShow

◆ licenseShow

◆ switchShow

You should also consider keeping hardcopy versions of key data such as passwords, license keys, and IP addresses. This is sensitive information and should be kept in a secure location.

Passwords are not saved in the configuration file, and are not uploaded during a configUpload. Password information should be saved in hardcopy in a secure location for emergency reference, subject to your security and password management policy.

WWN Card

If a Status LED on the WWN bezel flashes, the Power LED on the WWN bezel also flashes, for increased visibility.

To determine the status of the WWN card:

1. Check the LED indicators on the WWN bezel (see Figure 4-5 on page 4-16) and verify that they reflect the actual status of the components.

The WWN bezel covers the WWN card and allows its LEDs to shine through. The LEDs on the WWN bezel provide a consolidated view of the port blade status, CP blade status, and power supply status. The LED patterns may temporarily change during POST and other diagnostic tests; for information about how to interpret the LED patterns, refer to Table 4-7 on page 4-17.

2. Check the WWN card status using the commands listed in Table 4-5 if you have problems viewing or modifying the data stored on the WWN card. Difficulty retrieving or modifying this data could indicate a WWN card failure.

3. If the error log or serial console display error messages that indicate problems with WWN units (see Table 4-6), the WWN card might have failed.

Removing a Cable Management TrayTo remove the cable management tray (shown on the right in Figure 5-1 on page 5-4):

1. If the director is not operating: Remove the AC power connector cables and continue with step 2, then remove the cable management tray from the chassis. If the director is operating: Remove any cables from the tray, except the AC power connector cables.

2. Unscrew the two screws holding the tray to the chassis (see Figure 5-1 for location of screws) and save them for reuse.

3. With the AC power connector cables still plugged in, detach the cable management tray approximately 5 inches away from the chassis.

4. Switch one AC power switch off (for example, part A in Figure 5-1) and remove the corresponding AC power connector cable (for example, remove the cable from part B in Figure 5-1) from the chassis. Route the AC power connector cable through the tray.

5. Plug the AC power connector cable back in to the connector on the chassis, and switch the AC power switch on.

6. Repeat steps 4 and 5 for the other AC power switch and AC power connector cable. The cable management tray is now removed from the director chassis.

Installing a Cable Management TrayTo install a lower mounting cable management tray (shown on the right in Figure 5-1 on page 5-4):

1. If the director is not operating: Remove any cables and orient tray as shown in Figure 5-1, aligning the holes on the tray with the holes on the chassis. Then position and tighten the two screws. The cable management tray is installed.

If the director is operating: Skip to step 2.

2. Switch one AC power switch off (for example, part A in Figure 5-1 on page 5-4) and remove the corresponding AC power connector cable (for example, remove the cable from part B in Figure 5-1) from the chassis. Route the AC power connector cable through the tray.

3. Plug the AC power connector cable back in to the connector on the chassis, and switch the AC power switch on.

4. Repeat steps 2 and 3 for the other AC power switch and AC power connector cable.

5. Position and tighten the two screws to secure the cable management tray to the chassis.

6. Arrange the cables through or along the cable management tray as required. You should route the AC power connector cables out each side of the chassis.



Replacing a Port Blade and Filler PanelThis section describes how to remove and replace FC4-16-port blades and FC4-32 port blades (see Figure 5-2 on page 5-8) and blade filler panels (see Figure 5-3 on page 5-9) from the ED-48000B.

A filler panel should be removed only when being replaced with a port blade or new filler panel. Any slot that is not occupied by a port blade should be occupied by a filler panel to ensure correct cooling of the chassis and protection from dust. Slots are numbered from one through ten, from left to right, when facing the portside of the directors.

CAUTION!Wear a grounded ESD strap when handling a port blade. The chassis has a grounding connection above the power connectors (see Figure 5-6 on page 5-26).

Do not force the port blade installation. If the port blade does not slide in easily, ensure that it is correctly aligned inside the rail guides before continuing. Installing a port blade with incorrect alignment damages both the chassis and the replacement part.

Hold the port blade by the edges of the metal pan. Do not use the ejectors to hold a port blade.

Disassembling any part of a port blade voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the port blade.

Time and Items RequiredThe replacement procedure for each port blade or filler panel takes less than 10 minutes.

The following items are required for the port blade and filler panel replacement procedure:

◆ ESD (electrostatic discharge) grounding strap

◆ Workstation computer

◆ Replacement port blade or filler panel

Removing a Port BladeTo remove a port blade:

1. Check the power LED, status LED, and port status LED to identify any possible problems with the port blade. See Figure 4-1 on page 4-4 for LED locations on the port blade.

A failed port blade can be identified by inspecting the LEDs on the front panel of each port blade (see Figure 4-1). The WWN bezel on the nonport side of the ED-48000B also displays a power and status LED for each port blade. Refer to the appropriate hardware reference manual for additional information about the LEDs on the WWN bezel.

2. Establish a Telnet or console session.

Before replacing a port blade, establish a Telnet or console connection to determine a failure and verify operation after replacement. Use the switchShow command to view the status of blades on the director.

3. Check for adequate cable slack.

Make sure there is plenty of cable slack to remove a port blade without optical, power, or Ethernet cable obstruction. Refer to Managing Cables on page 2-10 for cabling guidelines.

4. Ensure that you have the proper spare part (filler panel or replacement port blade).

Make sure that the part number on the unit being replaced matches the replacement part number. The chassisShow command displays information about the port blades, including part numbers (xx-000xxxx-xx), EMC serial numbers, and additional status.



5. Ensure that traffic is not flowing through the port blade (port speed LEDs and port status LEDs should be off) prior to disconnecting cables.

Before removing any cables from a faulty port blade, make a note of cable order (identify each cable via its physical port). This reduces confusion during recabling. If multiple port blades are being replaced, replace one blade at a time to prevent confusion during cable reconnection. Before replacing a port blade, determine if it is the entire blade or only the SFPs that are faulty.

6. Disconnect all cables and SFP transceivers from the port blade.

7. Turn the port blade off by sliding the slider switch in the top ejector down, to the off position (see Figure 4-1 on page 4-4). This initiates a hot-swap request.

8. Wait for the power LED to turn off in response to the hot-swap request step 7 before uninstalling the port blade.

9. Unscrew the two thumb screws from the top and bottom ejectors on the port blade using the #2 Phillips screw driver.

10. Lever both ejectors open simultaneously to approximately 45 degrees and pull the port blade out of the chassis.

If the port blade is not being replaced by another port blade, install a filler panel to ensure correct cooling of the chassis and protection from dust. Refer to Installing a Filler Panel on page 5-12 for instructions.

Removing a Filler PanelTo remove a filler panel with pull tabs:

1. Unscrew the top and bottom captive screws on the filler panel.

2. Pull on the top and bottom pulling tabs to slide the filler panel out of the chassis.

Installing a Port BladeTo install a port blade:

1. Orient the port blade so that the ports are at the front of the chassis and the flat side of the port blade is on the left.


5

5-12


2. Open the ejectors to approximately 45 degrees, align the flat side of the port blade inside the upper and lower rail guides in the slot (see Figure 5-2 on page 5-8), and slide the port blade into the slot, with slight pressure to the left, until it is firmly seated.

3. Close the ejectors by pushing the handles toward the center of the port blade until the ejectors lock. The levering action of the handles seats the port blade in the slot.

4. Tighten the thumb screw inside each handle using the #2 Phillips screw driver.

5. Turn the port blade on by sliding the slider switch in the top ejector up, covering the thumb screw.

6. Verify that the power LED on the port blade is displaying a steady green light (it might require a few seconds to turn on). If it does not turn on, ensure that the port blade is firmly seated.

The LED patterns might temporarily change during POST and other diagnostic tests.

7. Install SFP transceivers and cables in the port blade, as required.

8. Group and route the cables as desired (refer to Managing Cables on page 2-10 for additional cabling instructions).

Installing a Filler PanelTo install a filler panel with pull tabs:

1. Orient the filler panel so that the captive screws are at the front of the chassis and the flat side of the filler panel is on the left.

2. Tighten the captive screws in place, fastening the filler panel in the chassis.



Replacing a CP BladeThis section describes how to remove and replace a control processor (CP) blade from the ED-48000B (see Figure 5-4 on page 5-15). Each ED-48000B has two CP cards: one located in slot 5 and the other in slot 6.

The ED-48000B can continue to operate while one CP card is replaced if the other CP card continues to operate and no failover occurs (you can prevent failover by entering the hadisable command). The active CP card is determined by the most recent failover.

The configuration on the active CP card is automatically mirrored to the standby CP card; this section includes steps to ensure that the new CP card boots up as the standby CP card.

The new CP card automatically assumes the IP address and host name assigned to the slot.

If the new CP card does not have the same firmware as the active CP card, it must be upgraded or downgraded to the same firmware version.

CAUTION!To ensure adequate system pressure for cooling purposes, leave the faulty CP blade in the slot until you are ready to perform the replacement procedure.

To allow the current configuration to be copied to a new CP blade, that CP blade must be installed while the other CP blade is still operating.

Wear a grounded ESD strap when handling a CP blade. A grounding connection is available on the chassis, above the power connectors.

Hold CP blades by the edges of the metal pans, not by the ejector handles.

Disassembling any part of a CP blade voids the part warranty and regulatory certifications. There are no user-serviceable parts inside a CP blade.

Verifying the Necessity of ReplacementIf you have not already done so, confirm that you need to replace the CP blade before continuing. The following events might indicate that a CP blade is faulty:

◆ The status LED on the CP blade is lit amber, or the power LED is not lit.

◆ The CP blade does not respond to Telnet commands, or the serial console is not available.

◆ The slotShow command does not show that the CP blade is enabled.

◆ The haShow command indicates an error.

◆ The calendar clock is inaccurate, or the CP blade does not boot up or shut down normally.

◆ Any of the following messages appear in the error log:

• “Slot unknown” message relating to a CP slot

• CP blade errors or I2C time-outs

• FRU: FRU_FAULTY messages for a CP blade

• Configuration loader messages or “Sys PCI config” messages

• Generic system driver messages (“FABSYS”)

• Platform system driver messages (“Platform”)

• EM messages that indicate a problem with a CP blade

• Function fail messages for the CP master

For more information about error messages, refer to the Fabric OS System Error Message Reference Manual.

Recording Critical Switch InformationBack up the switch configuration before you replace a CP blade. Refer to the Fabric OS Administrator’s Guide for backup information.

To record critical switch information:

1. Log in to the healthy CP blade as admin, using either a Telnet or a serial console connection.

2. Type haShow to determine which CP blade is active:

swDir:admin> haShowLocal CP (Slot 6, CP1) : ActiveRemote CP (Slot 5, CP0) : Standby, HealthyHA Enabled, Heartbeat Up, HA State Synchronized



Enter all remaining commands from the serial console for the active CP blade, unless otherwise indicated. For more information about commands, refer to the Fabric OS Command Reference Manual.

3. If the healthy CP blade is performing as the active CP blade, continue with step 5 on page 5-19. If the faulty CP blade is performing as the active CP blade, fail over the blades as described here:

a. Log in to the faulty CP blade as admin, using either a Telnet or a serial console connection.

If you connect successfully to the faulty CP continue to step b.

If you cannot connect to the faulty CP, remove the faulty CP blade for repair as follows:

– Turn the CP blade off and notify the ED-48000B of a hot-swap request by sliding the slider switch in the top ejector down to the off position (see Figure 4-1 on page 4-4).

– Wait until the active CP LED on the healthy CP blade is lit. You can remove the CP for repair.

b. Type haFailover. The healthy CP blade becomes the active CP blade.

c. Wait until the status LED on the healthy CP blade is no longer lit (indicating the failover is complete).

d. Type haShow from the healthy CP blade (the new active CP blade) to verify the failover.

Following is an example of failing over a CP blade in an ED-48000B:

Fabric OS (cp1)

cp1 login: adminPassword:swDir:admin> hashowLocal CP (Slot 6, CP1): ActiveRemote CP (Slot 5, CP0): Standby, HealthyHA enabled, Heartbeat Up, HA State synchronizedswDir:admin> hafailoverLocal CP (Slot 6, CP1): ActiveRemote CP (Slot 5, CP0): Standby, HealthyHA enabled, Heartbeat Up, HA State synchronized


5

5-18


Warning: This command is being run on a redundant controlprocessor(CP) system. If the above status does not indicate'HA State synchronized', then the CPs are not synchronizedand this operation will cause the active CP to reset. Thiswill cause disruption to devices attached to both switch 0and switch 1 and will require that existing telnet sessionsbe restarted. To reboot a single logical switch on thissystem, use the switchreboot command while logged in tothat logical switch.

Are you sure you want to fail over to the standby CP [y/n]?swDir:admin> haShowLocal CP (Slot 6, CP1) : Standby, HealthyRemote CP (Slot 5, CP0) : ActiveHA Enabled, Heartbeat Up, HA State Synchronized

4. Type firmwareShow to record the firmware version of the active CP blade.

5. Type haDisable from the active CP blade to prevent failover or communication between the CP blades during the replacement.

6. Logged in to the active CP, type the configUpload command to upload the switch configuration to a specified FTP server. Enter the requested information at the prompts.

Following is a sample of backing up the configuration files on the director:

swDir:admin> configUploadProtocol (scp or ftp) [ftp]: ftpServer Name or IP Address [host]: 123.456.78.90User Name [None]: userFile Name [config.txt]: config.txtPassword: xxxxxxxxupload complete

Removing a CP BladeThe ED-48000B director continues to operate while a CP blade is being replaced if the redundant CP blade is active and a failover does not occur (you can prevent failover by entering the haDisable command).

CAUTION!The core section within the ED-48000B director CP blades provides internal routing bandwidth that is always active on both CP blades. Removing a CP blade might impact user performance and should not occur until the replacement CP blade is ready to be installed.



WARNING

Do not replace the real-time clock battery on a CP blade. There is danger of explosion if the battery is incorrectly replaced or discarded. Contact your EMC service representative if the real-time clock begins to lose time.

To remove a CP blade:

1. Log in to the active CP as the admin user. You can use a serial cable or if you have connected the director to your IP network, you can use telnet, Web Tools, or Fabric Manger. You can determine which CP is active using the haShow command or view the active LED on the front of the CP.

2. If the CP you want to replace is the active CP issue the haFailover command. Wait until the failover has completed. Use the haShow command to verify the CPs are synchronized and the failover is complete.

3. Use the slotPowerOff command to disable the standby CP (the CP you want to replace).

4. Wait for the standby CP power LED turned off.

5. Disconnect all cables (modem, serial, Ethernet) from the standby CP.

6. Unscrew the thumb screw from both ejectors using the #2 Phillips screw driver.

7. Lever open both ejector handles simultaneously to approximately 45 degrees and pull the CP blade out of the chassis (see Figure 5-4 on page 5-15).

Installing a CP Blade

CAUTION!Do not force the installation. If the CP blade does not slide in easily, ensure that it is correctly oriented and aligned in the blade guides before continuing.

To ensure proper cooling, do not route cables in front of the exhaust vent (located at the top on the port side of the chassis).


5

5-20


WARNING

Use the same version of Fabric OS on both CP blades. Using different versions is not supported and might cause malfunctioning. If the replacement CP blade has a different version of Fabric OS, bring both blades to the same firmware version.

To install a new CP blade in the empty blade slot (#5 or #6), follow these steps:

1. Open the ejector handles to approximately 45 degrees; then, orient the CP blade so that the handles are toward you and the flat metal side is on your left.

2. Align the flat metal side of the CP blade inside the lower and upper blade guides in the slot; then, slide the CP blade into the slot until it is firmly seated.

3. Tighten the thumb screw inside each handle using the Phillips screwdriver.

4. Turn the CP blade on by sliding the ON/OFF switch in the top handle up, to cover the thumb screw.

5. Verify that the power LED is green (might require a few seconds). If not, ensure that the CP blade has power and is firmly seated and that the ejectors are in the locked position.

6. Connect the modem, serial, and Ethernet cables, as required to the new CP blade.

The new CP blade automatically assumes the IP address and hostname assigned to the slot.

7. Verify the installation, as described next.

Verifying Operation of the New CP BladeTo verify that boot and POST are complete on the new CP blade (a minimum of three minutes), and that the CP blades have achieved failover redundancy:

1. Wait until the status LEDs on both CP blades are not lit.



The status LEDs on the active CP blade displays amber until the active CP blade is fully operational, and the status LED on the standby CP blade displays amber until the CP blades have achieved failover redundancy.

2. Log in to the active CP as admin.

3. Enable the redundancy feature using the haEnable command.

4. Verify HA is enabled using the haShow command. The command output includes "HA Enabled Heartbeat Up" and "HA-state in sync."

If not, POST is not complete or the CP blades have not yet achieved redundancy. Wait one or two minutes and re-enter the command, until you can verify that redundancy has been achieved.

If haShow indicates any errors after redundancy is achieved, contact your switch service supplier.

5. Type slotShow. The command output shows the new CP blade as “enabled”:

swDir:admin> slotShow

Slot Blade Type ID Status--------------------------------- 1 SW BLADE 17 ENABLED 2 SW BLADE 17 ENABLED 3 SW BLADE 17 ENABLED 4 SW BLADE 17 ENABLED 5 CP BLADE 16 ENABLED 6 CP BLADE 16 ENABLED 7 SW BLADE 17 ENABLED 8 SW BLADE 17 ENABLED 9 SW BLADE 17 ENABLED 10 SW BLADE 17 ENABLED

swDir:admin>

6. Determine the version by typing firmwareShow.

The following example shows sample output for the firmwareShow command:

swDir:admin> firmwareShowLocal CP (Slot 6, CP1): Active Primary partition: v5.0.1

Replacing a Power Supply and Filler PanelUse this procedure to remove and replace a power supply. The ED-48000B can continue operating during the replacement if at least one power supply continues operating. A minimum of two power supplies are recommended.

You do not need to notify the ED-48000B of a hot-swap request for a power supply. The power supply bays are isolated; power supply filler panels are not required to ensure correct air flow.

The power supply unit slots are numbered 1 through 4 from bottom to top when facing the portside of the chassis. The AC power connector on the left provides power to the power supplies in slots 1 and 3; the AC power connector on the right provides power to the power supplies in slots 2 and 4 (see Figure 5-5 on page 5-25). The AC power connectors and the power supply slots are color-coded to identify which AC power connectors provide power to which power supply slots. Power supply unit labels for slots 1 and 3 and the corresponding AC power connector label are violet, and power supply unit labels for slots 2 and 4 and the corresponding AC power connector label are yellow.

For information about how to check the status of hardware components using Fabric OS commands, refer to the .

CAUTION!To protect against AC failure on the ED-48000B, EMC recommends a minimum of one power supply in slot 1 or 3 and one in slot 2 or 4. Additional power supplies might be required depending on how populated the switch is. For detailed information on minimum power supply requirements for each director, refer to the appropriate hardware reference manual.

If only two power supplies are installed and they are both installed in slots corresponding to the same AC power connector cable, unplugging a single AC power connector cable powers down the entire chassis.

Disassembling any part of the power supply voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the power supply.



Time and Items RequiredThe replacement procedure for each power supply takes less than 5 minutes.

A power supply unit or filler panel is required for the power supply replacement procedure.

Figure 5-5 illustrates the removal and installation of a power supply or filler panel, as described in the replacement procedures.

1. If the ED-48000B is not operating during the replacement procedure, skip to step 2.

If the ED-48000B is going to continue operating during the replacement procedure, check the power LEDs to verify that the minimum number of power supply units required is still functioning: A fully populated ED-48000B requires a minimum of one power supply unit in any slot at all times to ensure power to the director. For maximum availability of the ED-48000B director, you should have a minimum of one power supply unit in slot 1 or 3, and one in slot 2 or 4.

2. Push the locking tab toward the power supply unit and pull the handle out and down.

CAUTION!Support the power supply unit from underneath while removing it from the chassis.

3. Use the handle to pull the power supply out of the chassis.

4. If you are not replacing the removed power supply unit, orient the filler panel so the handle is vertical and the side tabs are on the right; then, push the filler panel into the slot.

Installing a Power Supply

CAUTION!Do not force the installation of the power supply unit or filler panel. If the part does not install easily, ensure that it is properly oriented.

Ensure that the handle is unlocked; otherwise, damage might occur to the power supply unit and chassis during the installation.

To install a power supply:

1. If a filler panel covers the slot, pull it out by the handle (see Figure 5-5).

2. Orient the power supply unit with the handle toward the front of the chassis and the LEDs on the left.

3. Unlock the handle by pressing the locking tab.

5. Verify that the power LED on the power supply unit displays a steady green light (see Figure 4-3 on page 4-11).

If it does not, ensure that both AC power connector cables are plugged in and both AC power switches are flipped to 1 (AC switch lights up green).



Replacing a Blower AssemblyThis procedure provides instructions for replacing an ED-48000B blower assembly. The ED-48000B requires a minimum of two operating blower assemblies at all times. To ensure continuous adequate cooling, maintain three operating blower assemblies at all times except for the brief period when replacing a blower assembly. The port blades automatically shut down if the internal temperature range is exceeded (up to 75º Celsius).

WARNING

If more than one blower must be turned off at the same time, the ED-48000B should be turned off to prevent overheating.

CAUTION!Disassembling any part of the blower assembly voids the part warranty and regulatory certifications. There are no user-serviceable parts inside the blower assembly.

Replacing the WWN Bezel and CardThe ED-48000B World Wide Name (WWN) card is highly reliable, containing fully redundant circuits; it does not usually require replacement under normal operating conditions.

Before replacing the WWN card, make sure you actually need to replace it by referring to the information provided under Verifying Necessity of Replacement on page 5-36. Contact your EMC Customer Service representative if you have any questions about whether the WWN card requires replacement.

If the WWN card does fail, the ED-48000B can continue operating until the new WWN card is installed if the configuration is not modified, no hardware components are replaced, and the ED-48000B is not rebooted.

The WWN card is located on the nonport side of the chassis underneath the WWN bezel (see Figure 1-2 on page 1-6).

This procedure requires a command line interface (CLI) to the ED-48000B. The CLI can be either a Telnet session or a serial console session; instructions are provided here for both.

If a serial console is used, all commands must be entered through the active CP card unless otherwise indicated. For command details, refer to the Fabric OS Command Reference Manual.

CAUTION!Do not power cycle or reboot the ED-48000B or replace the CP cards or port cards until the WWN card is verified as functional or a replacement WWN card is installed. If any of these events happen while the WWN card is failed or uninstalled, the configuration information is lost, and it will be necessary to reconfigure the ED-48000B after installing the new WWN card.

Disassembling any part of the WWN card voids the part warranty and regulatory certifications. The WWN card contains no user-serviceable parts.

This section provides the following information:

◆ Installing a WWN Card on page 5-39

Basic instructions for replacing the WWN card are provided in this document. Additional related information can be found in the ED-48000B WWN Bezel and Card Replacement Procedure.

Time and Items RequiredAllow approximately 20 minutes to replace the WWN card.

The following items are needed to replace the WWN card:

◆ Electrostatic discharge (ESD) grounding strap

◆ #2 Phillips screwdriver (required only for some versions of the WWN card)

◆ Required if a serial console session is used: serial cable and a workstation computer with a terminal emulator application (such as HyperTerminal for Windows systems or TIP for Solaris systems)

Verifying Necessity of ReplacementBefore replacing the WWN card, verify that the replacement is necessary. Any of the following events can indicate that the card requires replacement:

◆ Status LEDs on the WWN bezel (see Figure 4-5 on page 4-16) not reflecting the actual status of the components

◆ Problems viewing or modifying the data stored on the WWN card (see Table 5-2 on page 5-37)

◆ Error messages regarding WWN units #1 or #2 (see Table 5-3 on page 5-37)

To determine the status of the WWN card:

1. Check the LED indicators on the WWN bezel (see Figure 1-1 on page 1-4) and verify that they reflect the actual status of the components. The WWN bezel covers the WWN card and allows its LEDs to shine through. The LEDs on the WWN bezel provide a consolidated view of the port blade status, CP blade status, and power supply status. For information about how to interpret the LED patterns, refer to Table 5-1.

The LED patterns might temporarily change during POST and other diagnostic tests.

Table 5-1 WWN LED Patterns

LED Location/Purpose Color Status Recommended Action

Port blade/CP blade power Steady green Power is okay. No action required.

Port blade/CP blade status Steady amber Card is faulty. Check card.

No light (LED is off) Card is okay. No action required.

NOTE: If a blade slot or power supply bay has a filler panel installed, the corresponding LEDs on the WWN card do not light up.

Power supplypower/status

Steady green Power is okay. No action required.

Steady amber Power supply is faulty. Check power supply.

NOTE: If a status LED on the WWN bezel flashes, the power LED on the WWN bezel also flashes, for increased visibility.



2. Check the WWN card status using the commands listed in Table 5-2 if you have problems viewing or modifying the data stored on the WWN card. Difficulty retrieving or modifying this data could indicate a WWN card failure.

3. An error message is logged that indicates the status of the WWN unit (see Table 5-3).

WWN units correspond to information specific to the WWN card and are displayed by the chassisShow command.

Removing the WWN CardThis procedure requires a command line interface (CLI) to the ED-48000B. The CLI can be either a Telnet session or a serial console session.

1. Open a Telnet session to the ED-48000B and log in to the active CP as admin. The default password is "password".

Installing and Removing SFPs in a Port BladeTo install an SFP, position one of the SFP transceivers so that the key is oriented correctly to the port. Insert the transceiver into the port until it is firmly seated and the latching mechanism clicks. Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented.

To remove an SFP, pull the bale down and out, sliding the SFP transceiver out of the port blade.

The ED-48000B comes with an SFP extraction tool on the inside of the chassis door. The SFP extraction tool is designed to remove SFPs from an FC4-32 port blade, where the space is minimal and it is more difficult to fit fingers. Figure 5-9 displays the SFP extraction tool.

To use the SFP extraction tool, slide the SFP extraction tool on to the bale of the SFP and pull it out.

Chassis Replacement

OverviewThe ED-48000B must be removed from the fabric and powered off to perform this procedure. Contact your support provider if you have any questions about whether the chassis requires replacement.

CAUTION!Inform your SAN administrator that the ED-48000B must be disconnected from the fabric for the duration of the mechanical replacement.

If the switch is installed in a cabinet, ensure that the cabinet is balanced and secured mechanically and that the removal and installation procedure will not compromise cabinet stability.

Disassembling any part of the chassis voids the part warranty and regulatory certifications. The chassis itself contains no user-serviceable parts.

Time RequiredThe chassis replacement procedure takes approximately 3 hours to complete.


6Chassis Replacement

Items RequiredThe following items are required for the chassis replacement procedure:

◆ Electrostatic discharge (ESD) grounding strap

◆ ESD grounding pads for protecting control processor (CP) cards, 16-port cards, and the WWN card

◆ Serial cable and workstation computer with a terminal emulator application (such as HyperTerminal for Windows systems or TIP for Solaris systems), required only if serial console session used

◆ Pallet jack or hydraulic or assisted lift that raises a minimum of 55 inches (140 cm) and carries a minimum of 250 lbs. (113 kg)

◆ A surface to place the old chassis on, such as a second lift or the pallet originally provided with the old chassis

◆ 1/2-inch socket wrench to remove the pallet bolts

WARNING

An empty ED-48000B chassis weighs approximately 104 lbs (47 kg) and requires a hydraulic or assisted lift to move.

If the switch is installed in a cabinet, ensure that the cabinet is balanced and mechanically secured and that the removal and installation procedure will not compromise cabinet stability.

Do not place a ED-48000B chassis on the floor. It cannot be easily moved from the floor back onto a lift or pallet.

1. Uninstall the ED-48000B chassis from the installation location and place it onto an extra lift or on the shipping pallet originally provided with the chassis.Uninstall it from the cabinet, remove the rack mount hardware according to the manufacturer’s instructions, and set the hardware aside for use with the new chassis.

2. Unpack the new chassis:

a. Use scissors to cut the two bands that encircle the packaging.

b. Lift off the lid and remove the kits and foam from the top of the chassis.

c. Lift the cardboard box off the chassis and remove the plastic bag from around the chassis.Save packing materials for use when returning the old chassis.

d. Leave chassis attached to pallet if chassis must be transported to the installation location.

3. Transport the new chassis to the installation area, using a pallet jack or other assisted lift. If a pallet jack is available, place the tines into the gaps under the chassis.

Doorways must be wider than 36 in. (91 cm) to accommodate the chassis on the pallet.

4. Remove the pallet brackets and bolts:

a. Remove the four bolts holding the chassis to the pallet, using the 1/2-inch socket wrench.

Remove and Replace Chassis 6-13

b. Remove the four brackets from bottom of the chassis.

c. Save the pallet, pallet brackets, and pallet bolts for use when returning the faulty chassis, if required.

5. Install the chassis in the cabinet using a lift if necessary to raise the chassis to the correct level. Refer to the Connectrix EC-1500 Cabinet Setup and Installation Manual or the Mid-Mount Rack Kit Installation Procedure for more information.

CAUTION!To ensure adequate cooling, install the chassis with the cable side, which contains the air intake vents, facing the cool air aisle.



Install Components into New Chassis

CAUTION!Do not force the installation of any of the components. If the component does not slide in easily, ensure that it is correctly aligned and positioned before continuing.

Do not turn on the power until it is time to verify hardware operation (see step 1 on page 18).

1. Install the cable management tray on the new chassis, as described in Replacing the Cable Management Tray on page 5-3.

2. Verify that both AC power switches are off (set to “0”); then, connect power cords and power cord retainers (which should still be on the cords) to the new chassis:

a. Connect the power cords to the power connectors on the chassis. The power cords are designed with right and left bends to facilitate cord management. Ensure that the power cord has a minimum service loop of 6 inches available at the connection to the switch and that it is routed so that it is not exposed to stress.

b. Tighten the adjusting screw on each retainer until the power cord cannot be pulled out of the retainer. This prevents accidental disconnection from the chassis.

c. Connect the power cords to the PDUs within the Connectrix cabinet.

To protect against AC power failure, a separate power source is recommended for each cord. Routing the power cables out the sides of the chassis is recommended.

CAUTION!Do not turn the AC power switches on (set to “0”) until you verify the hardware of the system (refer Verify Correct Operation of System on page 6-20).

Setting Up and Installing Modems

IntroductionEach CP blade in the ED-48000B contains a modem serial port for connection to a Hayes-compatible modem. The modem serial ports are wired as standard DTE ports and have the same commands, login capabilities, and operational behavior as the terminal serial ports. However, asynchronous informational messages and other unsolicited text are not sent to the modem ports. No additional software is required to use modems with the ED-48000B.

The ED-48000B detects modems only during power on, reboot, or a CP blade failover sequence. Setting up the modems before powering on the ED-48000B is recommended.

For increased security, any active modem sessions are automatically disconnected if the modem cable is disconnected.

For optimal security, disconnect the modem cable when it is not in use


7Setting Up and Installing Modems

Using High-Availability ConnectivityHigh availability of the modem connection can be ensured by connecting a separate modem to each CP blade and then connecting both modems to a shared telephone line (see Figure 7-1). This ensures an available telephone connection to the active CP blade even if a failover occurs; however, it is necessary to log back in after a failover. When both CP blades are connected to a shared telephone line, callers are automatically dialed in to the active CP blade, which answers on the first ring. If the active CP blade cannot answer for any reason, the standby CP blade answers on the seventh ring and allows login to proceed.

If a modem connection is set up, connecting a modem to each CP blade is recommended.

Connecting Modems

Setting up the modems before powering on the ED-48000B and connecting it to the fabric is recommended.

The following items are required to set up two modems to work with the ED-48000B:

◆ Two Hayes-compatible modems, such as the Zoom/Modem V.92 EXT Model 3049

◆ Two standard modem cables, DB25 (male) to DB9 (female)

◆ One RJ-11 “Y” adapter for standard telco wiring or equivalent circuitry (three total connections)

◆ One analog telephone line

CAUTION!Powering off the ED-48000B before connecting cables to the modem ports is recommended.

To connect modems to the ED-48000B:

1. Optionally power off the ED-48000B.

2. Set up the two modem units and corresponding power connections, but do not power on the modems until all cables are attached.

3. Connect the modem cables to the modems and to the ED-48000B RS-232 modem ports, as shown in Figure 7-1 on page 7-4.

4. Connect the telephone “line” inputs on the modems to the RJ-11 “Y” connector.

This effectively places both modems on a single telephone line.

5. Optionally connect a telephone handset to one of the “phone” connections on the modems, as shown in Figure 7-1 on page 7-4.

6. Connect the “Y” adapter to an appropriate analog telephone line and document the dial-in number for later use.

7. Power on the modems and verify that the Modem Ready indicator illuminates on both units.

Connecting Modems 7-5

7-6


8. Power on the ED-48000B, or reboot if it was not powered off during the previous steps.

This allows the ED-48000B to recognize the modems.



Setting Up a Remote Modem SystemAfter the modems are connected, you can use a telco system to dial in to the modems and verify that they answer and communicate as expected. If a dial-out modem facility is not available, you can use a terminal emulation program on a computer workstation (or laptop) that has an attached modem.

This procedure is only required if a dial-out modem facility is not already available for testing the ED-48000B modem connections.

To set up the optional remote modem:

1. Connect the remote modem to the workstation, as shown in Figure 7-2.

2. Disable any serial communication programs running on the workstation (such as a synchronization program for a PDA).

Verifying the Modem ConnectionThis section provides information about how to verify that the modems are correctly connected.

This procedure requires either a telco system to dial in to the modems or a terminal emulation program on a laptop or workstation that has an attached modem. Refer to Setting Up a Remote Modem System on page 7-7 for instructions on setting up a remote modem with a terminal emulation program.

To verify the modem connection:

1. Verify that both modem cables are firmly connected.

2. Power on the modems, if not already on.

The modems must be powered on and operational before the ED-48000B is powered on, to allow the ED-48000B to detect the modems during boot.

3. Verify that both modems indicate they are ready by illuminating their “Clear to Send” (CS), “Terminal Ready” (TR), and “Modem Ready” (MR) indicators. If this does not occur, ensure that the modems are connected to a power source and are powered on, and check all modem cable connections.

4. Verify that POST is complete on the ED-48000B (a minimum of 3 minutes).

5. Dial in to the telephone number assigned to the ED-48000B, using a telco system to dial in to the modems or the setup described in Setting Up a Remote Modem System on page 7-7.

6. Observe the modem lamps: the Ring indicator should flash briefly as the telephone rings. If the Ring indicator does not flash on both units, recheck the incoming telephone lines to the modems.

7. Verify that after one ring, the “Off Hook” (OH) indicator illuminates on the modem associated with the active CP blade (usually in slot 5)and a login prompt is presented to the remote client.

7-10


8. Log in to the switch from the remote client as admin. The default password is “password”.

If the Off Hook indicator illuminates on the standby CP blade modem, recheck the modem cable connection to the active CP blade.

9. Log out of the modem session.

10. Remove the telco connector from the active CP blade modem, leaving the telco line from the standby CP blade connected to the “Y” connector (see Figure 7-1 on page 7-4).

The modem session is automatically disconnected if the modem cable is detached while a session is active.

11. Dial in to the telephone number assigned to the ED-48000B, as described in Setting Up a Remote Modem System on page 7-7.

12. Observe the modem lamps: the Ring indicator should flash only on the modem connected to the standby CP blade.

13. Verify that after seven rings, the Off Hook indicator on the standby CP blade modem is illuminated. A login prompt is presented to the remote client, and a message confirms that the standby CP blade is being logged in to. You can log in or disconnect the session, as desired.

14. Reconnect the telco connector to the active CP blade modem.

The ED-48000B modems are ready for use.

WARNING

Do not attempt to replace the real-time clock (RTC) battery on the CP blade. There is danger of explosion if the battery is incorrectly replaced or disposed of. Contact the ED-48000B supplier if the real-time clock begins to lose time.


ASpecifications

Terminal Serial Port SpecificationsEach CP blade provides a three-wire terminal serial port (labeled 10101) that has a “DB-9” male connector and an RS-232 signal subset.

To provide dust and ESD protection, keep the cover on the serial port whenever the port is not in use.The terminal serial port is intended primarily for use during the initial setting of the IP address and for service purposes.

The terminal serial port can be used to connect to a computer workstation or terminal without connecting to the fabric. The terminal device should be configured to 9600 baud, 8 data bits, no parity, 1 stop bit, with no flow control.

A 10 ft. (3.0 m) serial cable is provided with the switch; it can be converted from a DB-9 serial cable to an RJ-45-style serial cable by removing the adapter on the end of the cable.

The terminal serial port requires a straight-through serial cable with a female 9-pin subminiature-D connector. Use the pinouts listed in Table A-9.

Modem Serial Port SpecificationsEach CP blade has a modem serial port (labeled RS-232) with a fully RS-232 compliant DB-9 connector (see Figure 4-2 on page 4-8 for location of port).

For dust and electrostatic discharge (ESD) protection, keep the cover on the serial port whenever the port is not in use.

The modem port can be used for attaching a modem to each CP blade. The ED-48000B detects modems only during the power on or reboot sequences, and automatically initializes them for operation. If modems are connected to an operating switch, a power on/off cycle, reboot, or fast reboot is required to detect the modem(s).

If both modems are connected to the telephone line by a “Y” cable, the active CP blade answers on the first ring; if the active CP blade fails to answer, the standby CP blade answers on the seventh ring.

The pinouts for the modem serial port are shown in Table A-10.

Troubleshooting

IntroductionThe ED-48000B includes a number of diagnostic aids to assist with troubleshooting, including LEDs on the hardware, commands that display current status, diagnostic tests for hardware and software, and error messages. In addition, a number of managing and monitoring features are available, such as Fabric Manager, Web Tools, Fabric Watch, and Performance Monitoring.

If the ED-48000B does not operate as expected, the following steps can be taken to diagnose the problem:

◆ Check the LEDs and refer to the LED tables (refer to Chapter 4, Monitor System Components) for interpretation and recommended actions.

◆ Review the results of the last POST run by the ED-48000B (refer to Interpreting POST and Boot Results on page B-4).

◆ Review the error logs (refer to the Fabric OS System Error Message Reference Manual and the for more information).

◆ Type the sensorShow command to determine the status of the hardware components.

◆ Run diagnostic tests (refer to Diagnostics on page B-6).

◆ Reboot the switch or power the entire chassis off/on.

If the problem is still unresolved after these steps, contact your EMC Customer Service representative. The information required by your support provider in order to provide assistance is listed under [Where to Get Help on page -xiii.


BTroubleshooting

Obtaining Chassis and Component StatusThe CLI commands listed in Table B-1 provide status and environmental information about the chassis and its components. These commands provide information only, and they do not interrupt traffic flow. For more information about these commands, refer to the Fabric OS Command Reference Manual.

B-4

Troubleshooting

Interpreting POST and Boot ResultsThe ED-48000B performs power on self-test (POST) by default each time the chassis is powered on or the ED-48000B is rebooted or reset. The ED-48000B can be rebooted using the switchReboot, reboot (to reboot each CP individually), or fastBoot commands. The fastBoot command reboots the switches without running POST. If the active CP blade is rebooted, it fails over to the standby CP blade.

POST Each time the switch is powered on or reset, the switch automatically performs POST, a system check during which LED patterns might vary.

To verify that POST has completed without error:

◆ Verify that all LEDs return to a normal state after POST completes (refer to Chapter 4, Monitor System Components).

◆ If one or more LEDs do not return to a normal state, and this is not due to the switch being set to beacon, refer to the relevant LED table to identify and correct the problem. For port blades and CP blades, the slotShow command can be used to check the status of the slots. For information about turning beaconing on/off, refer to the Fabric OS Administrator’s Guide.

◆ Verify that the switch prompt appears when POST completes.

◆ If the switch prompt does not appear, POST was not successfully completed. Contact your EMC service representative for support.

◆ Review the system error log using the errShow or errDump commands.

◆ Any errors detected during POST are written to the system log, which is accessible through the errShow command. For information about error messages, refer to the Fabric OS System Error Message Reference Manual.

POST includes the following steps:

1. Preliminary POST diagnostics are run.

2. Operating system is initialized.

3. Hardware is initialized.


BTroubleshooting

4. Diagnostic tests are run on several functions, including circuitry, port functionality, ability to send and receive frames, all aspects of memory, parity, statistics counters, and serialization.

Boot In addition to POST, boot includes the following steps after POST is complete:

1. Universal port configuration is performed.

2. Links are initialized.

3. Fabric is analyzed. If any ports are connected to other switches, the switch participates in a fabric configuration.

4. The switch obtains a domain ID and assigns port addresses.

5. Unicast routing tables are constructed.

6. Normal port operation is enabled.

Interpreting POST and Boot Results B-5

B

B-6

Troubleshooting

DiagnosticsDiagnostic tests are automatically run during POST to check the status of the switch. Any error messages generated during POST are sent to the error logs and to the serial console, if connected.

Diagnostic tests can also be run manually to test and troubleshoot the hardware and the firmware, including internal connections and circuitry, transceivers, and port cables. However, diagnostic tests are generally intended for use by support personnel.

Error messages do not necessarily indicate that the switch requires maintenance.

Each diagnostic test can be implemented by entering the related command through a Telnet or serial session. For a list of diagnostic tests and commands, refer to the.

All diagnostic tests are run at link speeds of both 1 and 2 Gb/sec. They might temporarily lock the transmit and receive speeds to a specific speed. Some diagnostic tests require interconnecting the ports to each other or using loopback plugs. If ports are interconnected, the media (cables and transceivers) at each end of the connection must be of the same type. For example, short wavelength media must be connected to short wavelength media, and likewise with long wavelength media and copper media.

For more information about diagnostic tests and how to run them, refer to the Fabric OS Administrator’s Guide and the Fabric OS Command Reference Manual. For information about system error messages (errShow or errDump), refer to the Fabric OS System Error Message Reference Manual.
