Quick Start Guide

For the CoreBuilder™9000 Enterprise Switch

Interface Modules

Description

The 1000BASE-SX and 1000BASE-LX Gigabit Ethernet (GEN) Interface

Modules are 2-port interface modules for the CoreBuilder™9000

Enterprise Switch. These GEN Interface Modules serve as a 2-Gigabit

data channel between the Gigabit Ethernet Switch Fabric Module and

other IEEE 802.3z-compliant Gigabit Ethernet devices.

Key Features The GEN Interface Modules support the following key features:

■Two front panel IEEE 802.3z–compliant Gigabit Ethernet fiber-optic

ports that connect to a dedicated, non-blocking, redundant Gigabit

Ethernet backplane channel

■850nm multimode support on the 1000BASE-SX GEN Interface

Module

■1300nm single-mode support on the 1000BASE-LX GEN Interface

Module

■Management using the CoreBuilder 9000 Administration Console

(a command line interface) or Simple Network Management Protocol

(SNMP) applications by connecting through the Gigabit Ethernet

Switch Fabric Module

22-PORT 1000BASE-SX AND 2-PORT 1000BASE-LX GIGABIT ETHERNET INTERFACE MODULES QUICK START GUIDE

As shown in Figure 1, GEN Interface Modules are available in two

models:

■1000BASE-LX (order number 3CB9LG2SC). Ports on this module use

a 1300-nanometer, multimode/single-mode, optical transceivers

(colored blue) and SC connectors.

■1000BASE-SX (order number 3CB9LG2MC). Ports on this module

use an 850-nanometer, multimode, optical transceivers (colored

black) and SC connectors.

Figure 1 Front Panels of the GEN Interface Modules

Each GEN Interface Module has two ports on the front (see Figure 1) as

well as two ports on the rear of the module (not shown in Figure 1)

that connect to the chassis backplane. Because the front ports have a

pass-through function to the rear ports, they share port numbers

1 and 2 with the rear ports.

In the 16-slot chassis, you install modules vertically with the LEDs at the

top. In the 7-slot chassis, you install modules horizontally, as shown in

Figure 1.

Order of Installation

Activities

3Com recommends that you install CoreBuilder 9000 modules in the

following order:

1Management Modules

One Enterprise Management Engine (EME) is required (order number

3CB9EME). A second EME or an Enterprise Management Controller

(EMC) is optional (order number 3CB9EMC). By installing the

management modules first, you can complete the required system-level

setup procedures before you add other modules to the chassis. For

more information, see the following documents:

■Enterprise Management Engine User Guide

■Enterprise Management Engine Quick Start Guide

■Enterprise Management Controller Quick Start Guide

2Switch Fabric Modules

Because you manage a GEN Interface Module through the primary GEN

Switch Fabric Module, you must install one GEN Switch Fabric Module

first. In the 16-slot chassis, a second GEN Switch Fabric Module is

optional. See the Gigabit Ethernet Switch Fabric Module Quick Start

Guide for more information.

3Interface Modules

Install all interface modules, such as the 2-port 1000BASE-SX GEN

Interface Module, the 2-port 1000BASE-LX GEN Interface Module, or

the 36-port 10/100BASE-TX Fast Ethernet RJ-45 Layer 2 Switching

Module, last. You can install interface modules in any order, but see

your module documentation for chassis slot restrictions and

recommendations. For restrictions and recommendations for the GEN

Interface Modules, see “Module Placement in the Chassis” next in this

guide.

2-Port 1000BASE-SX and 2-Port 1000BASE-LX Gigabit Ethernet Interface Modules Quick Start Guide 7

Module Placement in

the Chassis

Note the following chassis slot restrictions and recommendations when

you choose a chassis slot for a GEN Interface Module.

In the CoreBuilder 9000 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 a CoreBuilder 9000 16-slot chassis:

■Do not install the module in slot 8 or 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 only have one connection to the

backplane and the GEN Switch Fabric Modules (see Table 2). If you

install a GEN Interface Module into one of these slots, you can only

use one of the module’s front panel ports. The GEN Switch Fabric

Module automatically disables the second port.

Table 1 and Table 2 list the relationship between the 24 Gbps Gigabit

Ethernet (GEN) Switch Fabric Module (3CB9FG24) and the interface

module slots in the 7-slot chassis and the 16-slot chassis, respectively.

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

administration purposes after you have completed the installation.

Installing the GEN

Interface Module

Follow this procedure to install a GEN Interface Module:

1Before you start the installation process, read “Safety Precautions” and

“Handling Precautions” earlier in this guide.

2Select a chassis slot for your module, following the restrictions and

recommendations in “Module Placement in the Chassis” earlier in this

guide.

3To expose the selected chassis slot, remove the blank faceplate that

covers the slot.

Save this faceplate, because you may need to cover an empty slot in

the future. Empty slots must be covered to ensure proper air flow and

cooling in the chassis.

4Open the module ejector handles.

5Begin to insert the module:

■In the 7-slot chassis, hold the module horizontally with the LEDs on

the left and insert the module using the guides on the left and the

right of the slot. See Figure 2.

■In the 16-slot chassis, hold the module vertically with the LEDs at

the top and insert the module using the guides on the top and the

bottom of the slot. See Figure 3.

CAUTION: Be careful not to twist or bend the module when you insert

it.

6Slide the module into the chassis by pushing firmly at the two ends of

the front panel near the ejector handles.

WARNING: Hazardous energy levels exist inside of the chassis. Do not

place hands or objects into the chassis or touch components on an

inserted module.
