Installing an Extender Card
Install the alarm extender card only in the lowest slot in the rear of the
Cisco 10005 ESR chassis.
All five top slots at the rear of the chassis should always be populated with
DS3 extender cards when the chassis is powered on. The DS3 extender card
extends the DS3 signals of the channelized T3 line card that is in the
corresponding slot in the front of the chassis. For example, a DS3 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.
To install an extender card into the rear of the chassis:
Note
If you are replacing an extender card, see the
“Removing an Extender Card”
section on page 3-19
before you begin this procedure.
Step 1
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.
Step 2
Hold the faceplate of the extender card with one hand and place your other hand
under the card carrier (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 is firmly seated in the
midplane connectors.
Step 4
Securely tighten both captive screws on the extender card.
