Follow the procedures in this section to remove and replace the extender cards at

the back of the chassis. Extender cards provide connectors for T3/E3 and alarm

relay interfaces.

To remove an extender card from the chassis:

Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis,

or to a bare metal surface on the chassis or frame.

Ensure that all wires and cables are disconnected from the extender card.

Loosen both captive screws on the extender card.

Hold the faceplate of the extender card with one hand, and place you other hand

under the card carrier (to support the weight of the card).

Slide the extender card out of the slot and place it on an antistatic surface, or in

an antistatic bag.

Install another extender card according to the

section on page

3-20. Do not leave the slot empty.
