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.
136195	Indicates that the receive power of the optical module is too high.

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 is too high.

Procedure

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.
- If not, go to step 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.
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.
Add -5 dBm (recommended) attenuators to the optical module.
If the problem persists after the preceding steps, collect alarms, logs, and configurations, and contact technical support personnel.
