Troubleshooting of Data Path Alarms

This chapter provides a description, severity, and troubleshooting procedure for each commonly encountered Cisco NCS 1010 data path alarm and condition. When an alarm is raised, refer to its clearing procedure.

EGRESS-AMPLI-GAIN-HIGH

Default Severity: Non Service-Affecting (NSA)

Logical Object: Controller OTS

The EGRESS-AMPLI-GAIN-HIGH alarm is raised when the EGRESS EDFA module cannot reach the gain setpoint. This condition occurs if the amplifier reaches its range boundaries and the Egress Amplifier Gain Degrade is high.

Clear the EGRESS-AMPLI-GAIN-HIGH Alarm

Procedure


Step 1

Adjust the gain setting to a correct value.

If the APC value is set to the disabled state, the applied gain results from the configuration. Therefore, you must adjust the gain setting to a high value.

Step 2

Check the overall system settings, performance, and the configured EDFA Gain.

If the APC value is set to the enabled state, it may be due to an unexpected long or short span, or due to other measured channels. If the alarm persists, it may indicate an amplifier hardware failure.

If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/c/en/us/support/index.html for more information or call Cisco TAC (1 800 553-2447).


EGRESS-AMPLI-GAIN-LOW

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

Logical Object: Controller OTS

The EGRESS-AMPLI-GAIN-LOW alarm is raised when the Egress Amplifier Gain Degrade is Low.

Clear the EGRESS-AMPLI-GAIN-LOW Alarm

Procedure


Step 1

Adjust the gain setting to a correct value.

If the APC value is set to the disabled state, the applied gain results from the configuration. Therefore, you must adjust the gain setting to a low value.

Step 2

Check the overall system settings, performance, and the configured EDFA Gain.

If the APC value is set to the enabled state, it may be due to an unexpected long or short span, or due to other measured channels. If the alarm persists, it may indicate an amplifier hardware failure.

If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/c/en/us/support/index.html for more information or call Cisco TAC (1 800 553-2447).


EGRESS-AUTO-LASER-SHUT

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: Controller OTS

Clear the EGRESS-AUTO-LASER-SHUT Alarm

Procedure


Step 1

For controller OTS, check the RX-LOC or RX-LOS-P alarm.

Step 2
