Removing And Replacing An Alarm Card - Cisco GSR12/60 - 12012 Router -AnyLAN, SONET/SDH Installation And Configuration Manual

Removing and Replacing an Alarm Card

The alarm card occupies the right-most slot in the upper card cage (labeled Alarm card).
Unlike the RP and line cards, the alarm card can only be installed in this slot.
The Cisco 12012 supports online insertion and removal of FRUs, which means you can
remove and replace an alarm card while the Cisco 12012 remains powered up.
You need the following tools and parts to perform this procedure:
•
1/4-inch flat-blade screwdriver
•
antistatic mat
•
ESD wrist strap
•
The replacement alarm card (Product Number GSR12-ALRM=)

Attach an antistatic wrist strap to yourself and to one of the two ESD connection
sockets located on the front edges of the upper card cage or to bare metal on the
frame.
Disconnect any cables attached to the alarm card connectors.
Loosen the two captive screws at the top and bottom of the alarm card. (See
Figure 7-15.)

levers. The alarm card backplane connector is smaller, has fewer pins, and is
easier to seat and unseat than the line cards and RP.
Using the screwdriver blade, gently pry at the top and bottom of the card to
unseat the card from the backplane connector.
Grasp the card carrier edge with one hand and place your other hand under the
carrier to support it (see Figure 7-15.) Slide the alarm card out of the card slot
and place it immediately on the antistatic mat.
