Chapter 2 Alarm Troubleshooting

2.7.40 CONTBUS-CLK-A

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) in order to report a Service-Affecting (SA) problem.

2.7.40 CONTBUS-CLK-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA) for ONS 15310-MA

SONET Logical Object: EQPT

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, complete the “Initiate a Force Switch for All Circuits on a Path Protection Span” procedure on page 2-151procedure. 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 2-149.

Step 2 Complete the appropriate procedure in the “2.10.3 Physical Card Reseating and Replacement” section on page 2-154for 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 2-148. If traffic was manually switched in a path protection, revert traffic to the original path by completing the “Clear an External Switching Command on a Path Protection Span” procedure on page 2-152.

2.7.41 CONTBUS-CLK-B

Default Severity: Minor (MN), Non-Service-Affecting (NSA) for ONS 15310-MA

SONET Logical Object: EQPT

An Inbound Interconnection Timing Control Bus 1 Failure alarm on the Slot 4 CTX2500 card occurs if the timing signal from the Slot 3 CTX2500 card has an error. If the Slot 4 CTX2500 card and all other cards on the shelf raise this alarm, the alarm processor on the Slot 3 CTX2500 card clears the alarm on the other cards and raises this alarm against the Slot 4 CTX2500 card only.
