Alarm Procedures
2.7.39 CONTBUS-IO-B
The CONTBUS-IO-B alarm is not used in the Cisco ONS 15310 platforms in this release. It is reserved
for development.
2.7.40 CTNEQPT-PBPROT
Default Severity: Critical (CR), Service-Affecting (SA)
SDH Logical Object: EQPT
The Interconnection Equipment Failure Protect Cross-Connect Card Payload Bus Alarm indicates a
failure of the main payload between the protect ONS 15310-MA SDH 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 2-153 for the standby ONS
15310-MA SDH.
b. If the reseat fails to clear the alarm, complete the “Physically Replace a Card” alarm on page 2-153
procedure for the standby ONS 15310-MA SDH.
Caution Do not physically reseat an active ONS 15310-MA SDH. Doing so disrupts traffic.
Step 2 If not all cards show the alarm, perform a CTC reset on the standby ONS 15310-MA SDH. Complete the
“Soft- or Hard-Reset a Controller Card” procedure on page 2-152 procedure.
Caution Avoid soft-resetting multiple ONS 15310-MA SDH cards at one time; doing so might cause an
unexpected traffic hit.
For the LED behavior, see the “2.8.2 Typical Card LED Activity During Reset” procedure on
page 2-146.
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 ONS 15310-MA SDH 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 2-153 procedure for the standby Ethernet card.
