Description

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

The receive power of an optical module is too low.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.219.2.4.5 Minor equipmentAlarm(5)

Parameters

Name Meaning
OID Indicates the ID of the MIB object.
Index Indicates the index.
EntityPhysicalIndex Indicates the index of the physical entity.
PhysicalName Indicates the name of the physical entity.
EntityTrapFaultID Indicates the error code.
EntityTrapReasonDescr Indicates the description of the alarm cause.

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 receive power of the optical module was too low.

Procedure

  1. Run the display transceiver slot slot-id verbose command in the system view to check whether the receive power Rx Power of the optical module is within the allowed range. If so, collect alarms, logs, and configurations, and contact technical support personnel.
  2. If no alarm on low receive power is generated and the peer interface is Up, go to step 5.
  3. If the peer interface is Down and an alarm on that is generated, rectify the peer interface.
  4. Check whether the optical fiber is faulty. If so, replace the optical fiber.
  5. Perform an external loopback test on the interface. If the interface is in Up state, perform loopback tests on the nodes along the transmission path to locate the failure point or link.
  6. Replace the local optical module.
  7. If the fault persists after the optical module is replaced, collect alarms, logs, and configurations, and contact technical support personnel.
