Installing or Replacing Extender Cards
This section describes how to install or replace an extender card in the Cisco 10005 chassis, and contains
the following procedures:

Installing an Extender Card
You can only install the alarm extender card in the lowest slot in the rear of the Cisco 10005 chassis.
The T3/E3 extender card extends the DS3 signals of the channelized T3 line card, located in the slot
directly opposite in the front of the chassis. For example, a T3/E3 extender card installed in the highest
slot in the rear of the chassis extends the signals of the channelized T3 line card that is installed in the
highest slot in the front of the chassis.
Use the following procedure to install an extender card into the rear of the Cisco 10005 chassis:
Note If you are replacing an extender card, see the “Removing an Extender Card” section on page A-3
before you begin this procedure.
Step 1 Attach an antistatic wrist strap to your wrist and either to an ESD socket on the chassis or to a bare metal
surface on the chassis or frame.
Step 2 Hold the faceplate of the extender card with one hand and place your other hand under the card (to
support the weight of the card). Position the card in front of the card cage slot.
Step 3 Carefully align the left and right edges of the extender card with the left and right guides in the chassis,
and slide the card into the slot until it begins to seat in the backplane connectors.
Step 4 Securely tighten both captive screws on the extender card.
