Module Descriptions

Key Features

This guide describes key installation information for two CoreBuilder

■ The 10-port 100BASE-FX Fast Ethernet Layer 2 Switching Module

(Model Number 3CB9LF10MC) has ten 100 Mbps Ethernet fiber-optic ports with SC connectors on its front panel and two 1-Gigabit ports on the back for connection to the chassis backplane.

■ The 20-port 10/100BASE-TX Fast Ethernet Layer 2 Switching Module

(Model Number 3CB9LF20R) has twenty 10/100 Mbps RJ-45 ports on its front panel and two 1-Gigabit ports on the back for connection to the chassis backplane.

Each of these FEN Switching Modules operates as a Layer 2 switch and occupies a single switching module slot in the CoreBuilder 9000 7-slot chassis, 8-slot chassis, or 16-slot chassis.

The 10/100BASE-TX and 100BASE-FX FEN Switching Modules support the following key 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

Audience Description

Safety Precautions

This guide is intended for trained technical personnel only. Do not attempt to install, remove, or replace the 10/100BASE-TX or 100BASE-FX FEN 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 the numbers to call in other locations, visit the 3Com Web site:

www.3Com.com/support/

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 a FEN 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 Devices.

ESD Safety Information

Electrostatic discharge (ESD) can damage components of the module. ESD, which occurs when a 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 a 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 a FEN Switching Module:

Verify that the module is the correct product by matching the 3C number

that is listed on the shipping box label to the 3C number that you ordered (Model Number 3CB9LF10MC for the 10-port 100BASE-FX Fast Ethernet Layer 2 Switching Module or Model Number 3CB9LF20R for the 20-port 10/100BASE-TX Fast Ethernet Layer 2 Switching Module).

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:

Installation

Prerequisites

Before you install a 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.

10-port 100BASE-FX Fast Ethernet Switching Module or the 20-port 10/100BASE-TX Fast Ethernet Switching Module:

■ In the 7-slot chassis:

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

■

Gigabit Ethernet (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.

■ Switching module slots in the 7-slot chassis, 8-slot chassis, and 16-slot

chassis, respectively

Table 4, Table 5, and Table 6 list the relationship between the following:

■ 24-port GEN Switch Fabric Module (SFM)

■ 20-port 10/100BASE-TX FEN Switching Module

■ Switching module slots in the 7-slot chassis, 8-slot chassis, and 16-slot

chassis, respectively

Table 7 and Table 8 list the relationship between the following:

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

■ 10-port 100BASE-FX FEN Switching Module

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

respectively

Table 9 and Table 10 list the relationship between the following:

■ 9-port GEN Switch Fabric Module (SFM)
