Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.7.195 PWR-FAIL-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

SONET 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 protection group or part of a UPSR, 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

“2.10.1 Protection Switching, Lock Initiation, and Clearing” section on page 2-156 for

commonly used traffic-switching procedures.

• If the alarm is reported against a 15310-CL-CTX or CTX2500 card, complete the “Soft- or

Hard-Reset a Controller Card” procedure on page 2-162.

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 ONS 15310-CL and

Cisco ONS 15310-MA Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL

or ONS 15310-MA.

Step 3 If the alarm does not clear, physically replace the power cable connection to the connector.

Step 4 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).

2.7.196 PWR-FAIL-B
