Alarm Troubleshooting

This chapter gives a description, severity, and troubleshooting procedure for each commonly encountered Cisco NCS 1001 alarm and condition. When an alarm is raised, refer to its clearing procedure.

0/PM [0|1] Unit Unsupported

Default Severity: Critical (CR), Service Affecting (SA)

Logical Object: EQUIPMENT

The 0/PM [0|1] Unit Unsupported alarm is raised when a an usupported PSU is plugged within NCS1001 chassis. The alarms has two forms because of the two PSU:

  • 0/PM0 unit unsupported
  • 0/PM1 unit unsupported

Clear the 0/PM [0|1] Unit Unsupported Alarm

Procedure

Replace the PSU with correct part number and hardware revision.

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).

0/RP0 Unit Unsupported

Default Severity: Critical (CR), Service Affecting (SA)

Logical Object: EQUIPMENT

The 0/RP0 Unit Unsupported alarm is raised when an unsupported CPU board is plugged in the chassis.

Clear the 0/RP0 Unit Unsupported Alarm

Procedure

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).

AMPLI-GAIN-LOW, AMPLI-GAIN-HIGH

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

Logical Object: OTS

The Amplifier Gain Low or High alarm is raised when the EDFA module cannot reach the gain setpoint. This condition occurs if the amplifier reaches its range boundaries.

Clear the AMPLI-GAIN-LOW, AMPLI-GAIN-HIGH Alarm

Procedure

Step 1

If the Amplifier-control-mode is set to "Manual", the applied gain comes from configuration. You need to adjust the gain setting to a correct value (not too low or too high).

Step 2

If the Amplifier-Control-Mode is set to "Automatic" it may be due to a too long/too short span or other conditions (i.e. measured channels). Check the overall system settings and performance.

Step 3

If the alarm persist, 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).

Step 2

The minimum channel power value and maximum channel power value shall be outside the channel-power-max-delta.

Step 3

Review the channel plan at system level (channel launch power vs channel path) and increase the channel-power-max-delta.

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).
