Quick Start Guide

For the CoreBuilder®9000 Enterprise Switch

Module Description The 9-port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module

(Model Number 3CB9LG9MC) for the CoreBuilder®9000 Enterprise

Switch can switch Gigabit Ethernet (GEN) connections to corporate

backbones and servers. The module has nine 1000BASE-SX GEN front

panel ports. It has the following number of backplane ports for

connection to the 24-port and the 9-port GEN Switch Fabric Modules:

The 9-port Gigabit Ethernet Layer 2 Switching Module (9-port GEN

Layer 2 Switching Module) includes its own embedded management

agent that supports standard Simple Network Management Protocol

(SNMP) Management Information Bases (MIBs).

Key Features The 9-port GEN Layer 2 Switching Module supports these features:

■Hot-swapping of modules

■Management using the Administration Console

(a command line interface), the Web Management suite of

applications with an Internet browser, or SNMP-based applications

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: Allow only trained service personnel to install, remove, or

replace any module in the chassis.

WARNING: Hazardous energy exists within the system. Use extreme

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

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.

WARNING: To ensure optical safety when installing the Gigabit Ethernet

Layer 2 Switching Module, comply with the following precaution:

Although the data communication LEDs used in this product meet the

regulatory requirements for casual exposure to the eye, as with any

source of bright light, it is advised that you do not look into the light

source.

LED Safety Information: IEC 825 and EN60825, Class 1 LED Device. For

connection only to Class 1 LED Device

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.

CAUTION: To prevent ESD-related damage:

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

module, ensuring that the strap makes good skin contact and is

properly grounded.

■Keep the module in its antistatic bag until you are ready to install it.

Handling Precautions When you handle the module, 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, verify that the module

ejector handles are open.

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

right module guides. In the 8-slot chassis or 16-slot chassis, match the

upper and lower module guides.

For details, see “Installation Prerequisites” and “Installing the Module”

later in this guide.

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 label to the 3C number that you ordered

(Model Number 3CB9LG9MC).

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

3Observing the caution instructions, remove the module from its antistatic

bag and inspect it for physical damage.

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

components, pins, leads, or solder connections.

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

it back in the shipping box, and contact your network supplier.

4Verify that the box also contains:

Installation

Prerequisites

Before you install the 9-port GEN Layer 2 Switching Module, make the

following preparations:

■Verify that the chassis is properly installed in a rack, on a table, or on a

shelf, according to the instructions in either of these guides:

■7-Slot Chassis Quick Installation Guide for the CoreBuilder 9000

Enterprise Switch

■Chassis Quick Installation Guide for the CoreBuilder 9000

Enterprise Switch 8-slot Chassis and 16-slot Chassis.

■Have a flat-blade torque screwdriver available to secure the module to

the chassis after you install it.

■Read the CoreBuilder 9000 Release Notes for the Fast Ethernet and

Gigabit Ethernet Layer 2 Switching Modules for important information

about installing and upgrading modules in an existing chassis or a new

chassis.

CAUTION: All modules in a CoreBuilder 9000 chassis must operate at

compatible software levels. You must verify the software release on all

new and existing modules in your chassis and upgrade as necessary. See

the CoreBuilder 9000 Release Notes for the Fast Ethernet and Gigabit

Ethernet Layer 2 Switching Modules for a module software compatibility

requirements table, mandatory upgrade procedures, and other important

information.

Module Placement

in the Chassis

Switch Fabric Module

■Install the module in slot 1, 2, 3, 4, 5, or 6.

■In the 8-slot chassis:

■Do not install the module in slot 7 or slot 8. These slots are

reserved for GEN Switch Fabric Modules.

■Install the module in slot 1, 2, 3, 4, 5, or 6.

9-Port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module Quick Start Guide 7

■In the 16-slot chassis:

■Do not install the module in slot 8 or slot 9. These slots are

reserved for GEN Switch Fabric Modules.

■To optimize backplane performance, install the module in slot 1, 2,

3, 4, 5, 6, 7, 10, 11, or 12.

■3Com recommends that you do not install the module in slot 13,

14, 15, or 16 because these slots have only one connection to the

backplane.

Table 1, Table 2, and Table 3 list the relationship between the following:

■24-port GEN Switch Fabric Module (SFM) (Model Number 3CB9FG24

or Model Number 3CB9FG24T)

■9-port GEN Layer 2 Switching Module

■Switching module slots in the 7-slot chassis, the 8-slot chassis, and the

16-slot chassis, respectively

Table 4 and Table 5 list the relationship between the following:

■9-port GEN Switch Fabric Module (SFM) (Model Number 3CB9FG9)

■9-port GEN Layer 2 Switching Module

■Switching module slots in the 7-slot chassis and the 8-slot chassis,

respectively

Use the table information to help you select a slot for your module, as

well as administer the system after you have completed the installation.
