ALM-3276800042 Indicates that the optical power exceeds the upper warning threshold or falls below the lower warning threshold 136220

Description

ENTITYTRAP/3/OPTMAYINVALID: OID [OID] The optical power exceeds the upper warning threshold or falls below the lower warning threshold. (Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityTrapFaultID=[INTEGER], EntityTrapReasonDescr="[OCTET]")

Impact on the System

This alarm does not affect system operating if the interface on which the optical module is installed works properly.

Possible Causes

The transmit power of the optical module is too high.

Procedure

  1. Run the display transceiver slot slot-id verbose command in the system view to check whether the transmit power Tx Power of the optical module is within the allowed range.

    • If so, services are not affected. Collect alarms, logs, and configurations and contact technical support personnel.
    • If not, go to step 2.

  2. Check whether the transmit power upper threshold of the optical module is within the acceptable range.

    • If so, run the transceiver diagnosis threshold tx-power command to change the transmit power upper threshold of the optical module. The alarm handling ends.
    • If not, go to step 3.

  3. Use an optical attenuator to reduce the transmit power of the optical module to the acceptable range. Check whether the alarm is cleared.

    • If so, the alarm handling ends.
    • If not, go to step 4.

  4. Replace the optical module, and check whether the alarm is cleared.

    • If so, the alarm handling ends.
    • If not, collect alarms, logs, and configurations, and contact technical support personnel.
