An Inbound Interconnection Timing Control Bus 1 Failure alarm on the Slot 3 CTX2500 card occurs if

the timing signal from the Slot 4 CTX2500 card has an error. If the Slot 3 CTX2500 card and all other

cards on the shelf raise this alarm, the alarm processor on the Slot 4 CTX2500 card clears the alarm on

the other cards and raises this alarm against the Slot 3 CTX2500 card only.

Clear the CONTBUS-CLK-A Alarm

Step 1 If a single traffic card is reporting the alarm and it is part of a path protection configration, complete the

“Initiate a Force Switch for All Circuits on a Path Protection Span” procedure on page 2-160 procedure.

If the traffic card is part of a 1+1 protection group, complete the “Clear a 1+1 Force or Manual Switch

Command” procedure on page 2-158.

Step 2 Complete the appropriate procedure in the “2.10.3 Physical Card Reseating and Replacement” section

on page 2-163 for the reporting card.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport

for more information or call Cisco TAC (1-800-553-2447).

Step 4 If traffic was manually switched in a 1+1 protection group, revert traffic to the original port by

completing the “Initiate a 1+1 Protection Port Force Switch Command” procedure on page 2-157. If

traffic was manually switched in a path protection configration, revert traffic to the original path by

completing the “Clear an External Switching Command on a Path Protection Span” procedure on

page 2-161.
