Step 5 If the reset card has not rebooted successfully, or the alarm has not cleared, call Cisco TAC (1-800-553-2447).

2.7.44 CTNEQPT-PBPROT

Default Severity: Critical (CR), Service-Affecting (SA) for ONS 15310-MA

SONET Logical Object: EQPT

The Interconnection Equipment Failure Protect Cross-Connect Card Payload Bus Alarm indicates a failure of the main payload between the protect CTX2500 card Slot 4 cross-connect card and the reporting traffic card. The cross-connect card and the reporting card are no longer communicating through the backplane. The problem exists in the cross-connect card and the reporting traffic card, or the controller card and the backplane.

Note This alarm automatically raises and clears when the Slot 4 controller card is reseated.

Clear the CTNEQPT-PBPROT Alarm

Step 1 If all traffic cards show CTNEQPT-PBPROT alarm, complete the following steps:

a.Complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-154for the standby CTX2500 card.

b.If the reseat fails to clear the alarm, complete the “Physically Replace a Card” alarm on page 2-154procedure for the standby CTX2500 card.

Caution Do not physically reseat an active CTX2500 card. Doing so disrupts traffic.

Step 2 If not all cards show the alarm, perform a CTC reset on the standby CTX2500 card. Complete the “Soft- or Hard-Reset a Controller Card” procedure on page 2-153procedure.

Caution Avoid soft-resetting multiple ONS 15310-MA cards at one time; doing so might cause an unexpected traffic hit.

For the LED behavior, see the “2.9.2 Typical Card LED Activity During Reset” procedure on page 2-147.

Step 3 Verify that the reset is complete and error-free and that no new related alarms appear in CTC. A green

ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.

If the cross-connect reset is not complete and error-free or if the CTX2500 card reboots automatically, call Cisco TAC (1 800 553-2447).

Step 4 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on page 2-154procedure for the standby Ethernet card.

Step 5 Determine whether the card is an active card or standby card in a protection group. Click the node view Maintenance > Protection tabs, then click the protection group. The cards and their status are displayed in the list.
