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.

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:

Verify 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).

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

Observing 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.

Verify that the box also contains:

■ CoreBuilder 9000 Release Notes for the Fast Ethernet and Gigabit

Ethernet Layer 2 Switching Modules

■ 9-Port 1000BASE-SX Gigabit Ethernet Layer 2 Switching Module

Quick Start Guide for the CoreBuilder 9000 Enterprise Switch (this guide)

If the listed contents are not in your shipping box, contact your network supplier.

All shipping boxes are reusable. After you remove the contents, replace the packing materials and store the shipping box for future use.

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

Note the following chassis slot restrictions and recommendations when you choose a chassis slot for the 9-port GEN Layer 2 Switching Module:

■ In the 7-slot chassis

Do not install the module in slot 7. This slot is reserved for a GEN

■

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

■ 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.
