1.2 Product Description

High-Density, Resilient Deployment Switch Solution for Gigabit Networking of Enterprise, Campus and Data Center

For the growing Gigabit network and IoT (Internet of Things) demand, IFS has launched a new-generation Stackable Gigabit

PoE+ Switch solution, the NS4802-24P-4S-2X, to meet the needs of IP surveillance, enterprises, telecoms and campuses for a

large-scale network deployment. The NS4802-24P-4S-2X is Layer 2+ Managed Stackable Gigabit PoE+ Switch, which supports

both IPv4 and IPv6 protocols and hardware Layer 3 static routing capability, and provides 24 10/100/1000Mbps Gigabit

Ethernet ports, 4 shared Gigabit SFP slots, 2 10G SFP+ uplink slots and another 2 dedicated 10G SFP+ stacked

interfaces for stacking the switch. Up to 16 units, 384 Gigabit Ethernet ports and 32 10Gbps SFP+ slots can be managed by a

stacking group and you can add ports and functionality as needed.

Efficient Single IP Management

The NS4802-24P-4S-2X applies the advantage of the stacking technology to managing the stack group with one single IP

address, which helps network managers to easily manage a stack of switches instead of connecting and setting each unit one

by one. The stacking technology also enables the chassis-based switches to be integrated into the NS4802-24P-4S-2X

Managed Switch at an inexpensive cost.

12

Highly-reliable Stacking Ability

Through its up to 40Gbps, bi-directional high bandwidth tunnel and stacking technology, the NS4802 gives the enterprises,

service providers and telecoms flexible control over port density, uplinks and switch stack performance. The stack redundancy

of the NS4802 ensures that data integrity is retained even if one switch in the stack fails. You can even hot-swap switches

without disrupting the network, which greatly simplifies the tasks of upgrading the LAN for catering to increasing bandwidth

demands.

Cost-effective 10Gbps Uplink Capacity

10G Ethernet is a big leap in the evolution of Ethernet. The two 10G SFP+ slot of the NS4802 supports Dual-speed,

10GBASE-SR/LR or 1000BASE-SX/LX, meaning the administrator now can flexibly choose the suitable SFP/SFP+ transceiver

according to the transmission distance or the transmission speed required to extend the network efficiently. They greatly support

SMB network to achieve 10Gbps high performance in a cost-effective way because 10GbE interface usually could be available

in Layer 3 Switch but Layer 3 Switch could be too expensive to SMBs. (Small Businesses)

Solution for IPv6 Networking

By supporting IPv6 / IPv4 dual stack and plenty of management functions with easy and friendly management interfaces, the

NS4802 is the best choice for IP surveillance, VoIP and wireless service providers to connect with the IPv6 network. It also helps

the SMB to step in the IPv6 era with the lowest investment but not necessary to replace the network facilities while the ISP

constructs the IPv6 FTTx edge network.

IPv4 and IPv6 VLAN Routing for Secure and Flexible Management

To help customers stay on top of their businesses, the NS4802 not only provides ultra high transmission performance and

excellent layer 2 technologies, but also offers IPv4/IPv6 VLAN routing feature which allows crossing over different VLANs and

different IP addresses for the purpose of having a highly secured, flexible management and simpler networking application.

Robust Layer2 Features

13

The NS4802 can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q

VLAN, Multiple spanning tree protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The NS4802

allows the operation of a high-speed trunk combining multiple ports. It enables up to 3 groups of 6 ports for trunk maximum and

supports connection fail-over as well.

Powerful Security

The NS4802-24P-4S-2X offers comprehensive layer2 to layer4 access control list (ACL) for enforcing security to the edge. It

can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP port

number or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based and MAC-based

user and device authentication. With the private VLAN function, communication between edge ports can be prevented to

ensure user privacy.

Enhanced Security and Traffic Control

The NS4802-24P-4S-2X also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent

IP snooping from attack and discard ARP packets with invalid MAC address. The network administrator can now construct

highly secured corporate networks with considerably less time and effort than before.

User-friendly Secure Management

For efficient management, the NS4802-24P-4S-2X managed switch is equipped with console, web and SNMP management

interfaces. With the built-in web-based management interface, the NS4802-24P-4S-2X offers an easy-to-use, platform

independent management and configuration facility. The NS4802-24P-4S-2X supports SNMP and it can be managed via any

management software based on standard of SNMP v1 and v2 protocol. For reducing product learning time, the

Centralized Power Management for Gigabit Ethernet PoE Networking

To fulfill the needs of higher power required PoE network applications with Gigabit speed transmission, the NS4802 features high-performance Gigabit IEEE 802.3af PoE (up to 15.4 watts) and IEEE 802.3at PoE+ (up to 30 watts) on all ports. It perfectly meets the power requirement of PoE VoIP phone and all kinds of PoE IP cameras such as IR, PTZ, speed dome cameras or even box type IP cameras with built-in fan and heater for high power consumption. The NS4802’s PoE capabilities also help to reduce deployment costs for network devices as a result of freeing from restrictions of power outlet locations. Power and data switching are integrated into one unit, delivered over a single cable and managed centrally. It thus eliminates cost for additional AC wiring and reduces installation time.

Built-in Unique PoE Functions for Surveillance Management

As a managed PoE Switch for surveillance network, the NS4802 features intelligent PoE Management functions:

Scheduled Power Recycling SMTP/SNMP Trap Event Alert PoE Schedule

Scheduled Power Recycling The NS4802 allows each of the connected PD (Powered Device) to reboot in a specific time each week. Therefore, it will reduce the chance of PD (Powered Device) crash resulting from buffer overflow.

SMTP/SNMP Trap Event alert Though most NVR or camera management software offer SMTP email alert function, the NS4802 further provides event alert function to help to diagnose the abnormal device owing to whether or not there is a break of the network connection, loss of PoE power or the rebooting response by PD Alive Check process.

PoE Schedule for Energy Saving Besides being used for IP surveillance, theNS4802 is certainly applicable to construct any PoE network including VoIP and wireless LAN. Under the trend of energy saving worldwide and contributing to the environmental protection on the Earth, the NS4802 can effectively control the power supply besides its capability of giving high watts power. The “PoE schedule” function helps you to enable or disable PoE power feeding for each PoE port during specified time intervals and it is a powerful function to help SMBs or enterprises save power and money.

2.2.3 Installing the SFP/SFP+ Transceiver

The sections describe how to insert an SFP/SFP+ transceiver into an SFP/SFP+ slot. The SFP/SFP+ transceivers are

hot-pluggable and hot-swappable. You can plug in and out the transceiver to/from any SFP/SFP+ port without having to power

down the Managed Switch, as the Figure 2-2-4 shows..

27

Figure 2-2-4: Plug-in the SFP/SFP+ Transceiver

Approved IFS SFP/SFP+ Transceivers

IFS Managed Switch supports both single mode and multi-mode SFP/SFP+ transceiver. The following list of approved IFS

SFP/SFP+ transceivers is correct at the time of publication:

Fast Ethernet Transceiver (100Base-X SFP)

Gigabit Ethernet Transceiver (1000BASX-LX-BX, Fiber Bi-Directional SFP)

28

10Gigabit Ethernet Transceiver (10GBASE-X SFP+)

■ 10 Gigabit Stacked SFP+ slot

10GBASE-SR/LR mini-GBIC slot, SFP+ Transceiver Module supports from 300 meters (multi-mode fiber) to up to 10

kilometers (single-mode fiber)

Model Speed (Mbps) Connector Interface Fiber Mode Distance Wavelength (nm) Operating Temp.

S40-2SLC-10 10G LC Single Mode 10km 1310nm 0 ~ 60 ℃

1. It is recommended to use IFS SFP on the Managed Switch. If you insert an SFP transceiver that is

not supported, the Managed Switch will not recognize it.

2. Port 21 to Port 24 are a shared SFP slot that supports the Gigabit and Fast Ethernet SFP

transceiver.

3. Port 25 to Port 26 are a shared SFP+ slot that supports the 10 Gigabit SFP+ transceiver and

Gigabit SFP transceiver.

1. Before we connect the NS4802 to the other network device, we have to make sure both sides of the SFP transceivers are

with the same media type, for example: 1000BASE-SX to 1000BASE-SX, 1000Bas-LX to 1000BASE-LX.

2. Check whether the fiber-optic cable type matches with the SFP transceiver requirement.

To connect to 1000BASE-SX SFP transceiver, please use the multi-mode fiber cable with one side being the male

duplex LC connector type.

To connect to 1000BASE-LX SFP transceiver, please use the single-mode fiber cable with one side being the male

duplex LC connector type.

Connect the Fiber Cable

1. Insert the duplex LC connector into the SFP/SFP+ transceiver.

2. Connect the other end of the cable to a device with SFP/SFP+ transceiver installed.

3. Check the LNK/ACT LED of the SFP/SFP+ slot on the front of the Managed Switch. Ensure that the SFP/SFP+

transceiver is operating correctly.

4. Check the Link mode of the SFP/SFP+ port if the link fails. To function with some fiber-NICs or Media Converters, user

has to set the port Link mode to “10GForce”, “1000 Force” or “100 Force”.

Remove the Transceiver Module

1. Make sure there is no network activity anymore.

2. Remove the Fiber-Optic Cable gently.

3. Lift up the lever of the SFP module and turn it to a horizontal position.

4. Pull out the module gently through the lever.

29

Figure 2-2-5: How to Pull Out the SFP/SFP+ Transceiver

Never pull out the module without lifting up the lever of the module and turning it to a horizontal

position. Directly pulling out the module could damage the module and the SFP/SFP+ module

slot of the Managed Switch.

2.3 Stack Installation

NS4802-24P-4S-2X

The NS4802 Managed Switch series provides a switch stacking function to manage up to 16 switches using a single IP address.

And up to 320 Gigabit Ethernet ports, 64 Gigabit TP/SFP ports and 32 high-capacity 10G SFP+ ports can be managed by a

stacking group and you can add ports and functionality as needed. You can add the NS4802 switch as needed to support more

network clients, knowing that your switching fabric will scale to meet increasing traffic demands.

Two types of stack topologies are supported by the NS4802.

Chain topology (same as a disconnected ring)

Ring topology

30

1. Please note that from now on the stacking example images are coming from NS4802,

however, as NS4802-24P stacking ports are on the front panel, but the stacking cable

connection rule is totally same with NS3601.

2. if you remove one of switch from stacking group and causes stacking ID without

sequence, please re-assign stacking ID from “Stack Configuration“before you make

the other operation.

3. Stack ports are port27 and port28 and the stacking ports could be used for stacking

only, it can’t be set to “uplink”.

Please find the following picture for sample connection.

Figure 2-21 Chain Stack topology

Figure 2-22 Ring Stack topology

31

2.3.1 Connecting Stacking Cable

Before attempting to connect stacking ports, verify that you have the required stack cables. The following cables are used to

connect stacked switches:

• NS-10G-CBL-50: 10G SFP+ Directly-attached Copper Cable (0.5M in length)

• NS-10G-CBL-2M: 10G SFP+ Directly-attached Copper Cable (2M in length)

• SFP+ Port 10GBASE-LR mini-GBIC Module (single-mode / 1310nm / max. 10km).

• SFP+ Port 10GBASE-SR mini-GBIC Module (multi-mode / 850nm / max. 300m)

• Standard 10GBASE-LR/SR mini-GBIC SFP+ Module.

There are two high-performance SFP+ stacked ports on the front panel for proprietary management stack.

Step 1: Plug one end of the cable into the “STX1” port and the other end into the ”STX2” port of the next device.

Step 2: Repeat the step for every device in the stack cluster, and then ending with the last switch.

Figure 2-23 Stacking Connection

Step 3: If you wish to implement stack redundancy, use the long stack cable to connect the stack port marked “STX1” on the

bottom switch to the port marked “STX2” on the top switch of the stack.

The stack port is for management and data packets to be transmitted between other IFS-5220 stackable

switch series. The stack ports can’t be configured with Layer 2 features via management interface.

Step 4: Power up the stack switches.

32

2.3.2 Management Stacking

The stack operation of the IFS Managed Switch supports Plug and Play Stacking connection and auto stack configuration.

Step 5: Once the stack starts operation, the Stack master will be automatically elected without any configuration. The Stack

master is indicated by a lit green “Master” LED on the front panel as Figure 2-24 shows.

Figure 2-24 Stack Master with “Master” LED lit

Step 6: When an IFS Switch is added to the stack, a Switch ID is automatically assigned to the IFS Switch. The automatic SID

assignment can be modified by choosing a different Switch ID on the Stack Configuration page. This method allows

Switch IDs to be assigned so that it is easier for the user to remember the ID of each switch.

1. The stack switch with the least priority ID or MAC Address number will become Master. Only

Master switch’s management interface (console, Telnet, Web and SNMP) is accessible.

It allows to build a stack of up to 16 NS4802 Switches. If there is the space limitation or power issue and you wish to stack all the

switches in different racks, use long stack cables to connect two stacks.

3. SWITCH MANAGEMENT

This chapter explains the methods that you can use to configure management access to the Managed Switch. It describes the

types of management applications and the communication and management protocols that deliver data between your

management device (workstation or personal computer) and the system. It also contains information about port connection

options.

This chapter covers the following topics:

Requirements

Management Access Overview

Administration Console Access

Web Management Access

SNMP Access

Standards, Protocols, and Related Reading

3.1 Requirements

Workstations running Windows 2000/XP, 2003, Vista/7/8, 2008, MAC OS9 or later, or Linux, UNIX , or other

platforms compatible with TCP/IP protocols.

Workstation is installed with Ethernet NIC (Network Interface Card)

Serial Port connect (Terminal)

• The above PC with COM Port (DB9 / RS-232) or USB-to-RS-232 converter

Ethernet Port connect

• Network cables - Use standard network (UTP) cables with RJ45 connectors.

The above workstation is installed with WEB Browser and JAVA runtime environment Plug-in

It is recommended to use Internet Explore 8.0 or above to access Managed Switch.

3.2 Management Access Overview

The Managed Switch gives you the flexibility to access and manage it using any or all of the following methods:

An administration console

Web browser interface

An external SNMP-based network management application

The administration console and Web browser interface support are embedded in the Managed Switch software and are

available for immediate use. Each of these management methods has their own advantages. Table 3-1 compares the three

management methods.

Method Advantages Disadvantages

Console • No IP address or subnet needed

• Text-based

• Telnet functionality and HyperTerminal

built into Windows

95/98/NT/2000/ME/XP operating

systems

• Secure

• Must be near the switch or use dial-up

connection

• Not convenient for remote users

• Modem connection may prove to be unreliable

or slow

Web Browser • Ideal for configuring the switch remotely

• Compatible with all popular browsers

• Can be accessed from any location

• Most visually appealing

• Security can be compromised (hackers need

only know the IP address and subnet mask)

• May encounter lag times on poor connections

SNMP Agent • Communicates with switch functions at

the MIB level

• Based on open standards

• Requires SNMP manager software

• Least visually appealing of all three methods

• Some settings require calculations

• Security can be compromised (hackers need

only know the community name)

3.3 Administration Console

The administration console is an internal, character-oriented, and command line user interface for performing system

administration such as displaying statistics or changing option settings. Using this method, you can view the administration

console from a terminal, personal computer, Apple Macintosh, or workstation connected to the Managed Switch's console

(serial) port.

Figure 3-1-1: Console Management

Direct Access

Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a

terminal-emulation program (such as HyperTerminal) to the Managed Switch console (serial) port. When using this

management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After making this connection,

configure the terminal-emulation program to use the following parameters:

The default parameters are:

115200 bps

8 data bits

No parity

1 stop bit

Figure 3-1-2: Terminal Parameter Settings

You can change these settings, if desired, after you log on. This management method is often preferred because you can

remain connected and monitor the system during system reboots. Also, certain error messages are sent to the serial port,

regardless of the interface through which the associated action was initiated. A Macintosh or PC attachment can use any

37

terminal-emulation program for connecting to the terminal serial port. A workstation attachment under UNIX can use an emulator

such as TIP.

3.4 Web Management

The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the

network through a standard browser such as Microsoft Internet Explorer. After you set up your IP address for the switch, you can

access the Managed Switch's Web interface applications directly in your Web browser by entering the IP address of the

Managed Switch.

Figure 3-1-3: Web Management

You can then use your Web browser to list and manage the Managed Switch configuration parameters from one central location,

just as if you were directly connected to the Managed Switch's console port. Web Management requires either Microsoft

Internet Explorer 7.0 or later, Safari or Mozilla Firefox 1.5 or later.

Figure 3-1-4: Web Main Screen of Managed Switch

3.5 SNMP-based Network Management

You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMP Network

Manager, HP Openview Network Node Management (NNM) or What’s Up Gold. This management method requires the SNMP

38

agent on the switch and the SNMP Network Management Station to use the same community string. This management

method, in fact, uses two community strings: the get community string and the set community string. If the SNMP Net-work

management Station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get

community string, it can only read MIBs. The default getting and setting community strings for the Managed Switch is public.

Figure 3-1-5: SNMP Management

If there are two LAN cards or above in the same administrator PC, choose a different LAN card by using the “Select Adapter” tool.

4. WEB CONFIGURATION

This section introduces the configuration and functions of the Web-based management from Managed Switch.

About Web-based Management

The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the

network through a standard browser such as Microsoft Internet Explorer.

The Web-based Management supports Internet Explorer 8.0. It is based on Java Applets with an aim to reduce network

bandwidth consumption, enhance access speed and present an easy viewing screen.

By default, IE8.0 or later version does not allow Java Applets to open sockets. The user has to explicitly

modify the browser setting to enable Java Applets to use network ports.

The Managed Switch can be configured through an Ethernet connection, making sure the manager PC must be set on the same

IP subnet address with the Managed Switch.

For example, the default IP address of the Managed Switch is 192.168.0.100, then the manager PC should be set at

192.168.0.x (where x is a number between 1 and 254, except 100), and the defa
