ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.4.5 hwOpticalInvalid 136195

Description

ENTITYTRAP/4/OPTICALINVALID: OID [oid] Optical module is invalid.(Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityTrapFaultID=136195, EntityTrapReasonDescr="Input Optical Power Too High")

The optical module does not work normally because the receive power was too high.

Attribute

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

Parameters

Name Meaning
oid

Indicates the MIB object ID of the alarm.

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 error code.

Impact on the System

The services on the corresponding interface will be interrupted.

Possible Causes

The receive power was too high.

Procedure

  1. Run the display interface command in the user 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. Check whether an alarm is generated for high transmit power on the peer optical module. If so, rectify the peer optical module fault first.
  3. Check whether the peer optical module and the local optical module are of the same type. If not, replace the local optical module with a new one to ensure they are of the same type.
  4. Add -5 dBm (recommended) optical attenuators to the local optical module.
  5. If the problem persists after the preceding steps, collect alarms, logs, and configurations, and contact technical support personnel.
