4-Port Gigabit Ethernet Layer 3

Switching Module (GBIC)

Quick Start Guide

For the CoreBuilder®9000 Enterprise Switch

Module Description The 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC) (Model

Number 3CB9RG4) for the CoreBuilder®9000 Enterprise Switch provides

high-port-density, line speed, Gigabit Ethernet switching and routing on

backbone networks running at Open Systems Interconnection (OSI)

Layer 3.

The module offers the following connectivity:

■Four Gigabit Interface Converter (GBIC) ports on the front panel can

be either 1000BASE-LX (single-mode fiber) or 1000BASE-SX

(multimode fiber).

■Four Gigabit Ethernet ports connect the module to the chassis

backplane.

Key Features The 4-port Gigabit Ethernet Layer 3 Switching Module (GBIC) supports

the following key features:

■High-density Gigabit Ethernet switching through the following

maximum number of GBIC front panel ports:

■24 ports in the 7-slot chassis and 8-slot chassis

■56 ports in the 16-slot chassis

■Ability to use multimode and single-mode 1000BASE-LX GBICs and

multimode 1000BASE-SX GBICs simultaneously on the front panel

■Ability to replace the module and GBIC ports while the chassis is

operating (which is known as hot swap)

24-Port Gigabit Ethernet Layer 3 Switching Module (GBIC) Quick Start Guide

■Stand-alone operations if a switch fabric module fails or is not

installed

■Full-duplex port operation (through front panel ports and backplane

ports)

■Management using the CoreBuilder 9000 Administration Console

command line interface, Web Management suite of applications, or

the Simple Network Management Protocol (SNMP)

For information about the software features that this module supports,

see the:

Port Numbering

The four front panel ports (1 – 4) correspond to the four Port Status LEDs.

Port numbers 5 – 8 on the rear of the module do not have corresponding

status LEDs on the front panel.

The logical port numbering depends on your network configuration. See

the CoreBuilder 9000 Implementation Guide for details.

Module Position in the Chassis

In the 7-slot chassis, you install all switching modules horizontally, with

the module and port status LEDs on the left side.

In the 8-slot and 16-slot chassis, you install all switching modules

vertically, with the module and port status LEDs at the top.

Audience Description This guide is intended for trained technical personnel only. Do not

attempt to install, remove, or replace CoreBuilder 9000 switching

modules if you have not had the proper training from 3Com. For training

information in the United States and Canada, call 1-800-NET-3Com. For

training information in other countries, visit the 3Com Web site:

Safety Precautions When you handle components in a CoreBuilder 9000 system, be sure

that you follow all safety precautions. To avoid electric shocks, burns, or

equipment damage, read and follow these warnings:

WARNING: This switching module must be installed, removed, or

replaced only by trained service personnel.

WARNING: Hazardous energy exists within the system. Use extreme

caution when you install, remove, or replace any module. When the

system is on:

■Never insert metal objects such as a screwdriver or a finger with

jewelry into open module slots.

■Do not touch any connections within the chassis with your hands or

fingers.

ESD Safety Information

Electrostatic discharge (ESD) can damage components of the module.

ESD, which occurs when the module is improperly handled, can cause

complete or intermittent failures on the module.

CAUTION: To prevent ESD-related damage:

■Always wear an ESD wrist strap (not provided) when you handle any

switching module, ensuring that the strap makes good skin contact

and is properly grounded.

■Keep the switching module in its antistatic bag until you are ready to

install it.

Handling

Precautions

When you handle the 4-port Gigabit Ethernet Layer 3 Switching Module

(GBIC), follow these precautions:

■Always handle the module by the front panel only.

■Do not touch the components, pins, leads, or solder connections.

■Do not twist or otherwise force the module into the chassis when you

insert it into the module guides.

■Before you push the module into the chassis, make sure that the

module ejector handles are open.

■When you slide the module into the 7-slot chassis, match the left and

right guides. When you slide the module into the 8-slot chassis or

16-slot chassis, match the upper and lower module guides.

Unpacking

Instructions

Use the following procedure when you unpack the module:

1Verify that the module is the correct model by matching the 3C number

that is listed on the shipping box to the 3C number that appears on your

order documentation (3CB9RG4).

2Remove the module, in its antistatic bag, from the shipping box.

3Remove the module from its antistatic bag and inspect it for physical

damage.

CAUTION: Handle the module by the front panel only. Do not touch any

components, pins, leads, or solder connections.

If the module appears to be damaged, replace it in its antistatic bag and

shipping box, and contact your network supplier.

4Ensure that the box also contains:

Choosing a Slot for

Your Module

This section provides guidelines for choosing the best slot for your 4-port

Gigabit Ethernet Layer 3 Switching Module (GBIC).

Installation in a 7-slot Chassis

You can choose any slot in the 7-slot chassis to house a 4-port Gigabit

Ethernet Layer 3 Switching Module (GBIC) — except slot 7, which is for

the wider switch fabric modules, and slots 8 and 9, which are for the

smaller management modules.

Table 1 and Table 2 show the relationship among the Gigabit Ethernet

(GEN) Switch Fabric Modules (24-port or 9-port) and the 4-port Gigabit

Ethernet Layer 3 Switching Module (GBIC) when both are installed in a

7-slot chassis. To summarize the table:

■The switching module can use all four of its backplane ports in slots

1 – 6, when used in conjunction with a 24-port GEN Switch Fabric

Module (3CB9FG24 or 3CB9FG24T). 3Com recommends that you

install this Layer 3 switching module in any of those slots.

■The switching module can use only its first backplane port (module

port number 5) when used in conjunction with a 9-port GEN Switch

Fabric Module (3CB9FG9).

Table 1 and Table 2 also show the relationship between the GEN Switch

Fabric Module backplane port numbers and the corresponding LED

indicator numbers.
