CHAPTER 1 INTRODUCTION
WGSW-404 and WGSW-2402A are ultra-fast high-performance switches with non-blocking switch
fabric of 16Gbps and 12.8Gbps. WGSW-404 is a backbone switch with 4-port 10/100/1000Mbps
RJ-45 and 4-slot for media expansion. WGSW-2402A is designed to be a workgroup switch with
24-port 10/100Mbps RJ-45 and 2-slot for media expansion. Their expansion slots support
1000Base-T, 1000Base-SX and 100Base-FX modules that provide great flexibility on enterprise and
FTTB application. In the following section, the short term “WGSW” will be used to represent both
WGSW-2402A and WGSW-404
The WGSW switch can be stacked up to 8 units together through Ethernet interface and managed by
single IP. You can stack 8 WGSW-2402A to get up to 192 100Base-TX ports plus 2 Gigabit port or 8
WGSW-404 to get 50 Gigabit ports in single stack. Mix them in a single stack is also possible to get
maximum flexibility. Most stacked switches are limited by the length of a proprietary stack cable,
WGSW switch, however, the maximum distance between two stacked switches can be up to 2
kilometers using Ethernet stack connectivity.
Designed as the Layer 2 switch but with layer 3 software routing function, the WGSW can easily fit in
your network configuration and can be executed for its management functions through the console
telnet and the web. SNMP MIBII, Bridge MIB, RMON groups 1,2,3,9 and enterprise private MIB are
also supported to get the maximum management functionality.
The standard IEEE 802.1Q with VLAN tagging feature makes logically separating nodes easier, with up
to 128 VLAN groups allowed on the WGSW switch. IGMP snooping is provided to prevent flooding of IP
multicast traffic. Port security and MAC addresses filtering are also included as a standard feature to
enhance overall network access security.
8 priority queues on Gigabit port and 4 on 10/100port are provided with versatile scheduling methods
including delay bound, strict priority, WFQ and best effort. This ensures critical applications get the
bandwidth and priority they need. Rate control is also supported to allow bandwidth allocation based
on ports.
Throughout this user’s manual, the Intelligent Gigabit Ethernet Switch, WGSW-404 and WGSW-2402A
will be referred to as the Managed Switch or the Switch or WGSW.

2.4 Installing the Switch
The Switch is designed for office use, where it can be free standing, desktop-mounted, or mounted in
most standard 19-inch equipment racks. If you prefer, you can rack-mount the Switch in a wiring closet
or equipment room using two mounting brackets and six screws.
When choosing a location for the Switch, observe the following guidelines:
Make sure the Switch is accessible and that the cables can be connected easily.
Keep cabling away from sources of electrical noise such as radios, transmitters, and broadband
amplifiers as well as power lines and fluorescent lighting fixtures.
Prevent water or moisture from entering the Switch case.
Make sure there are no obstructions to restrict airflow around the Switch. We recommend that you
provide a minimum of 25 millimeter (1-inch) clearance.
Do not place liquids or other objects on top of the Switch.
If the Switches are freestanding, do not stack more than four switches on top of one another.
- 13 -
2.4.1 Pre-Installation Considerations
Fast Ethernet Topology Considerations
If you will be using the Switch for Fast Ethernet (100 Mbps) operation, observe the following guidelines:
The maximum unshielded twisted-pair (UTP) cable length is 100 meters (328 feet) over Category 5
cable.
Single-repeater topologies permit a total network span of 325 meters (1066 feet).
Full-Duplex Considerations
The Switch provides full-duplex support for its Fast Ethernet ports. Full-duplex operation allows frames
to be sent and received simultaneously, doubling a link’s potential data throughput. If you will be using
the Switch in full-duplex mode, the maximum UTP cable length is 100 meters (328 feet) over Category
5 cable.
2.4.2 Desktop or Shelf Mounting
To install the Switch on a desktop or shelf, simply complete the following steps:
Step 1 Place the Switch on a desktop or shelf near an AC power source. Step 2 Keep enough ventilation space between the Switch and the surrounding objects.
Note: When choosing a location, keep in mind the environmental restrictions. Please also
refer to Chapter 1, section 1.3 product specification for the details.
Step 3 Connect the Switch to network devices.
A. Connect one end of a standard network cable to the 10/100 RJ-45 ports on the front of
the Switch.
B. Connect the other end of the cable to the network devices such as printer servers,
workstations or routers.
C.
Note: It is strongly recommended to use the UTP Category 5 network cabling with RJ-45 tips
for the network connection. For more information, please see the Cable Specifications in Appendix A, Cable Specifications.
Step 4 Supply power to the Switch.
A. Connect one end of the power cable to the Switch. B. Connect the power cube end of the power cable to a standard wall outlet.
When the Switch receives power, the Power LED should remain solid Green.

CHAPTER 3 CONFIGURATION
This chapter explains the methods that you can use to configure management access to the 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:
Management Access Overview
Key Concepts
Key Guidelines for Implementation
Administration Console Access
Web Management Access
SNMP Access
Standards, Protocols, and Related Reading
3.1 Management Access Overview
The Switch gives you the flexibility to access and manage the Switch 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 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.

3.1.1 Administration Console
The administration console is an internal, character-oriented, menu-driven 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 Switch’s console (serial) port.
There are two ways to use this management method: via direct access or modem port access. The
following sections describe these methods. For more information about using the console, refer to
Chapter 4 Menu-Driven Console Management.
3.1.2 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 Switch console (serial)
port.
When using this management method, a null-modem 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:
115,200 bps
8 data bits
No parity
1 stop bit
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 terminal-emulation program for connecting to
the terminal serial port. A workstation attachment under UNIX can use an emulator such as TIP.
- 17 -
3.1.3 Modem Port Access
You can access the Switch’s administration console from a PC or Macintosh using an external modem
attached to the console (serial) port. The Switch management program provides a Console Port
screen, accessible from the Basic Management screen, that lets you configure parameters for modem
access (see Chapter 4 Menu-Driven Console Management). After configuring when you have
configured the external modem from the administration console, the Switch transmits characters that
you have entered as output on the modem port. The Switch echoes characters that it receives as input
on the modem port to the current ad-ministration console session. The console appears to be directly
connected to the external modem.
3.2 Web Management
The Switch provides a browser interface that lets you configure and manage the Switch remotely. After
you set up your IP address for the Switch, you can access the Switch’s Web interface applications
directly in your Web browser by entering the IP address of the Switch. You can then use your Web
browser to list and manage switch configuration parameters from one central location, just as if you
were directly connected to the Switch’s console port. For more information, see Chapter 5, Browser Management.
Web Management requires either Microsoft Internet Explorer 4.01 or later or Netscape Navigator 4.03
or later.
Netscape Navigator — if you use Netscape Navigator 4.03 or 4.04, install the Netscape JDK 1.1
Patch. Download the patch from the following location:
http://www.netscape.com/
If you encounter problems accessing Help files when you use Netscape, clear the browser memory
cache and disk cache, and restart the browser.
Internet Explorer — if you use Internet Explorer 4.01, install the latest 4.01 Service Pack 1. This
service pack makes Internet Explorer Year 2000 compliant and fixes other product-support issues.
Download the 4.01 Service Pack 1 from the following location:
http://www.microsoft.com/msdownload/iebuild/ie4sp1_win32/en/ie4sp1_win32.htm
If the above link is unavailable, download the service pack from the Microsoft home page:
http://www.microsoft.com
- 18 -
3.3 SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the Switch. This
management method requires the SNMP 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 network 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 gets and sets community strings for the
Switch are public.
3.4 Protocols
The Switch supports the following protocols:
Virtual terminal protocols, such as Telnet
Simple Network Management Protocol (SNMP)
3.4.1 Virtual Terminal Protocols
A virtual terminal protocol is a software program, such as Telnet, that allows you to establish a
management session from a Macintosh, a PC, or a UNIX workstation. Because Telnet runs over
TCP/IP, you must have at least one IP address configured on the Switch before you can establish
access to it with a virtual terminal protocol.
Note: Terminal emulation differs from a virtual terminal protocol in that you must connect a terminal
directly to the console (serial) port.
3.4.2 SNMP Protocol
Simple Network Management Protocol (SNMP) is the standard management protocol for multi-vendor
IP networks. SNMP supports transaction-based queries that allow the protocol to format messages and
to transmit information between reporting devices and data-collection programs. SNMP runs on top of
the User Datagram Protocol (UDP), offering a connectionless-mode service.
- 19 -
3.4.3 Management Architecture
All of the management application modules use the same Messaging Application Programming
Interface (MAPI). By unifying management methods with a single MAPI, configuration parameters set
using one method (console port, for example) are immediately displayable by the other management
methods (for example, SNMP agent of Web browser).
The management architecture of the Switch adheres to the IEEE open standard. This compliance
assures customers that the Switch is compatible with, and will interoperate with other solutions that
adhere to the same open standard.
- 20 -
Chapter 4 Menu-Driven Console Management
The Switch provides a menu-driven console interface for configuration purposes. The Switch can be
configured either locally through its RS-232 port or remotely via a Telnet session. This chapter
describes how to configure the Switch using its menu-driven console. The figures in this chapter will
base on WGSW-2402A, for WGSW-404, however, the setup steps are the same.
4.1 Logging on to the Switch
Enter the console interface factory default console name “admin” without password (or enter a
user-defined pass-word if you changed the factory default password). The Switch Management screen
in Figure 4-1 appears, with the Basic option highlighted.
Note:
Only one console and three telnet-users can log on to the Switch concurrently. However, it is
not recommended that multiple users modify the configuration at the same time.
