Interface Modules

Description

Key Features

The 1000BASE-SX and 1000BASE-LX Gigabit Ethernet (GEN) Interface Modules are 2-port interface modules for the CoreBuilder 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.

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

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.

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.

Audience Description

Safety Precautions

This guide is intended for

trained technical personnel

only. Do not attempt to install, remove, or replace a CoreBuilder 9000 GEN Interface Module if you have not had the proper training from 3Com. For training information, call 1-800-NET-3COM.

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 a GEN Interface Module.

WARNING:

Hazardous energy exists within the CoreBuilder system. Use extreme caution when you install, remove, or replace a GEN Interface Module.

When the system is on, never insert metal objects such as a screwdriver or a finger with jewelry into open module slots.

When the system is on, do not touch any connections within the chassis with your hands or fingers. Do not insert metal objects into the backplane.

WARNING:

To ensure optical safety when installing GEN Interface

Modules, comply with the following precaution:

Although the data communication lasers 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 a GEN Interface 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 GEN Interface Module, ensuring that the strap makes good skin contact.

■

Keep the GEN Interface Module in its antistatic bag until you are ready to install it.

Handling Precautions

Unpacking

Instructions

When you handle a GEN Interface Module, follow these precautions:

■

Always handle the module by its 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 slot guides.

■

Before you push the module into the chassis, make sure that the module ejector handles are open.

■

To slide the module into the 16-slot chassis, match the upper and lower module guides; in the 7-slot chassis, match the left and right module guides.

Use the following procedure when you unpack a GEN Interface Module:

Verify that the GEN Interface Module is the correct product by matching the order number that is listed on the shipping box label to the order number that is listed on your sales invoice (3CB9LG2MC or 3CB9LG2SC).

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

Ensure that the box also contains:

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

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

Remove the GEN Interface Module from its antistatic bag and inspect it

for physical damage.

Installation

Prerequisites

CAUTION:

Handle the module by the front panel only. Do not touch

any components, pins, leads, or solder connections.

If the module appears to be damaged, replace it in its antistatic bag and shipping box, and contact your supplier.

Before you install a GEN Interface Module, make sure that the CoreBuilder 9000 chassis is properly installed in a rack, on a table, or on a shelf, according to the instructions in the

Order of Installation

Activities

3Com recommends that you install CoreBuilder 9000 modules in the following order:

Management 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

Switch 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

Guide

for more information.

Interface Modules

Gigabit Ethernet Switch Fabric Module Quick Start

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

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.
