20-Port 100BASE-FX (MT-RJ) Fast Ethernet Layer 2 Switching Module Quick Start Guide

Installing the Module

To install the 100BASE-FX (MT-RJ) Fast Ethernet Layer 2 Switching
Module:
1 Before you start the installation process, read "Safety Precautions" and
"Handling Precautions" earlier in this guide.
2 Select a slot for your FEN Switching Module, according to the restrictions
and recommendations in "Module Placement in the Chassis" earlier in
this guide.
3 To expose the selected chassis slot, remove the blank faceplate that
covers the slot.
Save this faceplate in case you need to cover an empty switch fabric
module slot in the future. Empty slots must always be covered to ensure
proper air flow and cooling in the chassis.
3Com recommends that you install only one module at a time and that
you remove the faceplate only for the slot where you intend to install the
module. Having either a module or a faceplate on each side of the
module that you are installing helps ensure that the spring-loaded screws
on the module align properly with the holes in the chassis.
4 Open the module ejector handles.
5 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 8-slot chassis and 16-slot chassis, hold the module vertically
with the LEDs at the top and insert the module using the guides at the
top and the bottom of the slot. Figure 3 shows the installation in a
16-slot chassis.
CAUTION: Be careful not to twist or bend the module when you insert it
into the chassis.
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.
