Installing the Module

To install a FEN Switching Module:

Before you start the installation process, read and follow the instructions

in “Safety Precautions,” “Handling Precautions,” and “Installation Prerequisites” 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 a slot for the module, remove the blank faceplate.

Save this faceplate in case you need it in the future. Empty slots must be covered to ensure proper airflow and cooling in the chassis.

3Com recommends that you remove the faceplate only for the slot where you intend to install an individual module; leave the remaining faceplates 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 to the

left and begin to insert the module using the guides on the left and the right of the slot. Figure 2 shows the module position in a 7-slot chassis.

■ In the 8-slot chassis and 16-slot chassis, hold the module vertically

with the LEDs at the top and begin to insert the module using the guides on the top and the bottom of the slot. Figure 3 shows the module position in a 16-slot chassis. The module position is the same in an 8-slot chassis.

CAUTION: Do not twist or bend the module when you insert it.

Slide the module into the chassis by pushing firmly on the two ends of

the front panel near the ejector handles.

WARNING: Hazardous energy exists inside the chassis. Do not place hands or objects into the chassis or touch any components on an inserted module.

To engage the module with the backplane, use both hands to perform

the following steps:

Push firmly at the two ends of the front panel near the ejector handles

until you feel the module connectors make firm contact with the backplane connectors.

Put your left thumb on the left or top ejector handle and your right

thumb on the right or bottom ejector handle. Simultaneously, push the ejector handles in towards the front panel until each handle is parallel with the front panel.

You feel a slight resistance as the connectors fully engage.

CAUTION: If there is too much resistance when you try to close the ejector handles, the module backplane connector 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.

To secure the module in the chassis, tighten the spring-loaded screws to a

torque specification of 3 to 5 inch-pounds.

CAUTION: Verify that the module screws are properly aligned with the threaded holes in the chassis. If the screws are not aligned when you tighten them, you may strip the threads and make it impossible to secure the module.

To ensure that you tighten screws to torque specification, use a torque screwdriver.

WARNING: To ensure adequate cooling airflow and continued product safety agency compliance, install blank faceplates over all empty slots.

If the chassis is powered on, the module initialization process begins.

Administration Console

The Administration Console is the embedded menu-driven command line interface that you access from a terminal or through terminal emulation software.

To manage the module from the Administration Console:

For information about how to log in to the EME, see the CoreBuilder 9000 Enterprise Management Engine User Guide.

At the EME prompt, enter:

connect <slot>.1

where <slot> is the chassis slot number of the module that you want to manage, and the number after the decimal point is a subslot number, which is always 1.

The top level of the Administration Console menu for the module appears.

Enter command strings to manage the module. For example, to display a

module baseline, enter:

module baseline display

For information about the Administration Console module commands, see the Command Reference Guide.

Web Management

Web Management applications are an embedded part of the system. They include WebConsole, DeviceView, and Performance monitoring tools. Additional installable applications include online Help.
