100BASE-FX and 10/100BASE-TX Fast Ethernet Switching Modules Quick Start Guide
7
Consider the following slot restrictions when you choose a chassis slot
for Switching Modules:
■
Slots 8 and 9 are reserved only for switch fabric modules, which are
1.5 inches in width. You cannot install FEN Interface Modules in
these slots.
■
Slots 13 through 16 have only one connection to the backplane.
The 100BASE-FX and 10/100BASE-TX Switching Modules have two
backplane ports. The second backplane port on the 100BASE-FX
module is for future use, and if necessary, can be installed in slots
13 through 16 without affecting its bandwidth. Install the
10/100BASE-TX module in other slots that support both ports.
Installing the Module
To install a Fast Ethernet Switching Module:
1
Before you start the installation process, read the “Safety Precautions”
section earlier in this document.
2
To expose a slot for the module, remove a blank faceplate from a
chassis slot.
You can install the module in any slot except slots 8 and 9.
3
Open the module ejector handles.
4
Hold the module vertically with the LEDs at the top and then insert the
module into the guides at the top and bottom of the slot.
CAUTION:
Be careful not to twist or bend the module when you insert
it.
5
Slide the module into the chassis by pushing firmly at the top and
bottom of the front panel (Figure 2).
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.
