CAUTION
Loss of service
All connectors on the side interconnect right must be
disconnected before removing the circuit pack. This results
in a loss of service to all line cards in the copper-distribution
shelves.
Action
Ensure that all connectors are labeled with the same designations as the
label on the side interconnect right circuit pack (CDS 1A through CDS 7B).
Remove the ABM shelf cover as shown in Chapter 3, "Removing covers and
grilles."
Turn off all circuit breakers on the breaker interface panel labeled CDS1
through to CDS 7.
Disconnect all cables from the side interconnect right circuit pack connectors.
(These are the cables going to the copper distribution shelves.)
Loosen the two screws located on the side of the circuit pack: one screw is
located beside the label CDS 2A (J3) ; the other is located beside label CDS
6B (J12) .
Pull the ejector latches to disengage the circuit pack from the shelf, and pull
it completely from its slot.
Gently push the replacement circuit pack in until the ejector latches come in
contact with the shelf. Then push the latches in toward the circuit pack to
engage the circuit pack with the backplane connector.
Secure the circuit pack by tightening the two hexagonal hold-down screws.
Starting from the top connector on the circuit pack, re-connect each of the
connectors removed in step 4. Securely fasten each of the hold-down screws
on the connectors.
After all copper distribution shelf connectors are re-connected, return each of
the breaker interface panel breakers to the on position.
Replace the shelf cover.
