Step 4 Verify that the reset is complete and error-free and that no new related alarms appear in CTC. Verify the
LED appearance: A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates
a standby card.
Step 5 If the alarm does not clear, complete the “Remove and Reinsert (Reseat) a Card” procedure on
page 2-153 for the reporting card.
Step 6 If the alarm does not clear, log into the Technical Support Website at
http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC (1 800
553-2447).
2.7.176 PROV-MISMATCH
For information about this alarm or condition, refer to the “Alarm Troubleshooting” chapter in the
Cisco ONS 15454 DWDM Troubleshooting Guide. That guide discusses all DWDM alarms.
2.7.177 PWR-FAIL-A
Default Severity: Minor (MN), Non-Service-Affecting (NSA)
SDH Logical Object: EQPT
The Equipment Power Failure at Connector A alarm occurs when there is no power supply from the main
power connector to the equipment. This alarm occurs on the electrical line card or the controller card.
Warning
Before working on equipment that is connected to power lines, remove jewelry (including rings,
necklaces, and watches). Metal objects will heat up when connected to power and ground and can
cause serious burns or weld the metal object to the terminals.
Statement 43
Clear the PWR-FAIL-A Alarm
Step 1 If a single port has reported the alarm, take the following actions depending on the reporting entity:
• If the reporting port is an active traffic line port in a 1+1/LMSP protection group or part of a SNCP,
ensure that an APS traffic switch has occurred to move traffic to the protect port.
Note Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To
avoid this, perform an external switch if a switch has not already occurred. See the
“2.9.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-146 for
commonly used traffic-switching procedures.
• If the alarm is reported against a ONS 15310-MA SDH, complete the “Soft- or Hard-Reset a
Controller Card” procedure on page 2-152.
Step 2 If the alarm does not clear, reseat the power cable connection to the connector. For more information
about power connections, refer to the “Install Hardware” chapter in the Cisco ONS15310-MA SDH
Procedure Guide.
