Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.139 PWR-REDUN

Minor (MN), Non-Service Affecting (NSA)

The Redundant Power Capability Lost (PWR-REDUN) alarm applies to cards that have two built-in fuses (such as newer optical cards). The alarm indicates that one of the fuses has blown and must be serviced. When this alarm occurs, the card’s power redundancy is lost because only one card power connection can contact one of the redundant power supplies.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

Procedure: Clear the PWR-REDUN Alarm

Step 1 The card fuse is not field-replaceable. Complete the “Physically Replace a Card” procedure on page 2-130.

Note When replacing a card with an identical type of card, no additional CTC provisioning is required.

Step 2 Log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447) to arrange a card return for service.

2.6.140 RAI

Not Alarmed (NA), Non-Service Affecting (NSA)

The Remote Alarm Indication (RAI) condition signifies an end-to-end failure. The error condition is sent from one end of the SONET path to the other. RAI on the DS3XM-6 card indicates that the far-end node is receiving a DS-3 AIS condition (see page 2-16).

Procedure: Clear the RAI Condition

Step 1 Complete the “Clear the AIS Condition” procedure on page 2-16.

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.141 RCVR-MISS

Major (MJ), Service Affecting (SA)
