Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.78 FE-LOF

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

The Far End LOF (FE-LOF) condition occurs when a far-end node reports an LOF (DS-3) alarm (see page 2-79).

The prefix FE occurs when the main alarm is occurring at the far-end node and not at the node reporting the FE-LOF condition. Troubleshoot the FE condition or condition by troubleshooting the main alarm at its source. Both alarms or conditions clear when the main alarm clears.

Procedure: Clear the FE-LOF Condition

Step 1 To troubleshoot an FE condition, determine which node and card links directly to the card reporting the FE condition.

Step 2 Log into the node that links directly to the card reporting the FE condition.

Step 3 Complete the “Clear the LOF (DS-3) Alarm” procedure on page 2-79. The procedure also applies to FE-LOF.

Step 4 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.79 FE-LOS

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

The Far End LOS (FE-LOS) condition occurs when a far-end node reports an LOS (DS-3) alarm (see page 2-83).

The prefix FE occurs when the main alarm is occurring at the far-end node, and not at the node reporting the FE-LOS condition. Troubleshoot the FE condition by troubleshooting the main alarm at its source. Both alarms or conditions clear when the main alarm clears.

Procedure: Clear the FE-LOS Condition

Step 1 To troubleshoot the FE condition, determine which node and card links directly to the card reporting the FE condition.

Step 2 Log into the node that links directly to the card reporting the FE condition.

Step 3 Complete the “Clear the LOF (DS-1) Alarm” procedure on page 2-78.

Step 4 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
