20-Port10/100BASE-TXFast Ethernet Layer 2 Switching Modules Quick Start Guide

For the CoreBuilder® 9000 Enterprise Switch

Module Descriptions This guide describes key installation information for two CoreBuilder® 9000 Fast Ethernet (FEN) Switching Modules:

The 10-port100BASE-FXFast Ethernet Layer 2 Switching Module (Model Number 3CB9LF10MC) has ten 100 Mbps Ethernetfiber-opticports with SC connectors on its front panel and two1-Gigabitports on the back for connection to the chassis backplane.

The 20-port10/100BASE-TXFast Ethernet Layer 2 Switching Module (Model Number 3CB9LF20R) has twenty 10/100 MbpsRJ-45ports on its front panel and two1-Gigabitports 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-slotchassis,8-slotchassis, or16-slotchassis.

Key Features The10/100BASE-TXand100BASE-FXFEN Switching Modules support the following key features:

Hot-swappingof modules

Management using the Administration Console

(a command line interface), the Web Management suite of applications with an Internet browser, or SNMP-basedapplications

Audience Description This guide is intended fortrained technical personnel only. Do not attempt to install, remove, or replace the10/100BASE-TXor100BASE-FXFEN Switching Modules if you have not had the proper training from 3Com. For training information in the United States and Canada, call1-800-NET-3COM.For the numbers to call in other locations, 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: 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 preventESD-relateddamage:

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-slotchassis, match the left and right module guides. In the8-slotchassis or16-slotchassis, match the upper and lower module guides.

For details, see “Installation Prerequisites” and“Installing the Module” later in this guide.

Unpacking Use the following procedure when you unpack a FEN Switching Module:

Instructions

1Verify 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-port100BASE-FXFast Ethernet Layer 2 Switching Module or Model Number 3CB9LF20R for the20-port10/100BASE-TXFast Ethernet Layer 2 Switching Module).

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

Module Placement

in the Chassis

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-SlotChassis Quick Installation Guide for the CoreBuilder 9000 Enterprise Switch

Chassis Quick Installation Guide for the CoreBuilder 9000 Enterprise Switch 8-slotChassis and16-slotChassis.

Have a flat-bladetorque 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 Modulesfor 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 theCoreBuilder 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.

Note the following chassis slot restrictions and recommendations when you choose a chassis slot for the 10-port100BASE-FXFast Ethernet Switching Module or the20-port10/100BASE-TXFast Ethernet Switching Module:

In the 7-slotchassis:

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-slotchassis:

Do not install the module in slot 7 or slot 8. These slots are reserved for GEN Switch Fabric Modules.

Install the FEN Switching Module in slot 1, 2, 3, 4, 5, or 6.

10-Port100BASE-FXand20-Port10/100BASE-TXFast Ethernet Layer 2 Switching Modules Quick Start Guide

7

In the 16-slotchassis:

Do not install the module in slot 8 or slot 9. These slots are reserved for GEN Switch Fabric Modules.

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 GEN Switch Fabric Module.

24-portGEN Switch Fabric Module (SFM)

20-port10/100BASE-TXFEN Switching Module

Switching module slots in the 7-slotchassis,8-slotchassis, and16-slotchassis, respectively

Table 7 andTable 8 list the relationship between the following:

9-portGEN Switch Fabric Module (SFM) (Model Number 3CB9FG9)

10-port100BASE-FXFEN Switching Module

Switching module slots in the 7-slotchassis and8-slotchassis, respectively
