Chapter 2 Alarm Troubleshooting

Alarm Procedures

2.6.71FE-EQPT-NSA

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

The Far End Common Equipment Failure Non-Service Affecting (FE-EQPT-NSA) condition occurs when a non-service affecting equipment failure is detected on a far-end XTC card.

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

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 FE-EQPT-NSA 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 Clear the main alarm. Refer to the appropriate alarm section in this chapter for troubleshooting instructions.

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).

2.6.72 FE-EXERCISING-RING

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

The Far End Exercising Ring (FE-EXERCISING-RING) condition occurs when far-end optical (traffic) cards in a two-fiber BLSR are being tested using the EXERCISE RING command. The prefix FE means the main alarm is occurring at the far-end node and not at the node reporting the FE-EXERCISING-RING condition.

Note FE-EXERCISING-RING is an informational condition. It does not require troubleshooting.

2.6.73 FE-EXERCISING-SPAN

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

The Far End Exercising Span (FE-EXERCISING-SPAN) condition occurs when far-end optical (traffic) cards in a BLSR are being tested using the EXERCISE SPAN command.The prefix FE means the main alarm is occurring at the far-end node and not at the node reporting the FE-EXERCISING-SPAN condition.
