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.

Installing the GEN

Interface Module

Follow this procedure to install a GEN Interface Module:

Before you start the installation process, read “Safety Precautions” and “Handling Precautions” earlier in this guide.

Select a chassis slot for your module, following the restrictions and recommendations in “Module Placement in the Chassis” earlier in this guide.

To 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.

Open the module ejector handles.

Begin 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.

Slide 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.

To engage the module connectors and the chassis backplane

connectors, apply forward pressure to the module front panel. You feel a slight resistance as the connectors engage.

CAUTION:

If the resistance is too great, the module connectors and the backplane connectors may not be aligned. Forcing the module into place can damage the module connectors and backplane connectors. If necessary, remove and reinsert the module, ensuring that the connectors are properly aligned. Do not tighten the spring-loaded screws to seat the module.

If modules are already installed to the left of this module in a 16-slot chassis or installed beneath this module in a 7-slot chassis, you may need to apply sideways or downward pressure on that adjacent module to have your module line up correctly in its slot. Applying this pressure compresses the thin strip of rubber-like material (which exists for electromagnetic interference purposes) at the edge of the front panel of the adjacent module.

Ensure that the module remains fully seated in the backplane

connectors while you close the ejector handles. Use one hand to hold the module in place, and use your other hand to

close one ejector handle at a time until the handles are parallel with the front panel.

To secure the module front panel to the chassis, tighten the

spring-loaded screws to a torque specification of 3–5 inch-pounds.

CAUTION:

To ensure adequate cooling air flow and continued product safety agency compliance, install blank faceplates over all empty slots.

Verifying Module

Operation

The GEN Interface Modules each have one Module Status LED and two Port Status LEDs. Watch the LEDs during system power-on to verify proper module operation. During the power-on diagnostic test, both the Module Status and Port Status LEDs flash for approximately 1 second, and then reflect the active status of the module as described in Table 3.

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

Managing the

Module

You configure and manage the front panel ports on the GEN Interface Module using the Administration Console, which is a command line interface that you access from a terminal that is connected through the Enterprise Management Engine (EME).

At the command prompt, you do not connect directly to a GEN Interface Module; you manage GEN Interface Modules by connecting to the primary GEN Switch Fabric Module backplane ports that correspond to where you have installed the GEN Interface Module in the chassis. To learn how GEN Switch Fabric Module backplane ports are assigned to chassis slots, see Table 1 and Table 2 earlier in this guide.

To manage GEN Interface Module ports from the Administration Console:

For information about logging in to the EME, see the

Enterprise Management Engine User Guide.

At the prompt, enter:

connect <slot>.1

CoreBuilder 9000

Where <slot> is the slot number of the module that you want to manage, and the number after the decimal point is a subslot number (the subslot number is always 1).

Because you manage the GEN Interface Modules through the GEN Switch Fabric Module, you always connect to slot 7 in the CoreBuilder 9000 7-slot chassis and to slot 8 or slot 9 in the CoreBuilder 9000 16-slot chassis.

This command connects you to the primary GEN Switch Fabric Module, and the Administration Console displays the top-level menu prompt.

To manage a GEN Interface Module port, enter commands for the

corresponding backplane port on the primary GEN Switch Fabric Module.
