BASETRAP_1.3.6.1.4.1.2011.5.25.129.2.17.1 hwOpticalPowerAbnormal

Description

BASETRAP/3/OPTPWRABNORMAL: OID [oid] Optical module power is abnormal. (EntityPhysicalIndex=[INTEGER], BaseTrapSeverity=[INTEGER], BaseTrapProbableCause=[INTEGER], BaseTrapEventType=[INTEGER], EntPhysicalContainedIn=[INTEGER], EntPhysicalName="[OCTET]", RelativeResource="[OCTET]", ReasonDescription="[OCTET]")

An alarm is generated when the transmit or receive power of an optical module is out of the allowed range.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.129.2.17.1 Minor equipmentAlarm(5)

Parameters

Name Meaning
OID Indicates the ID of the MIB object.
EntityPhysicalIndex Indicates the physical index.
BaseTrapSeverity Indicates the alarm severity.
BaseTrapProbableCause Indicates the possible causes of the alarm.
BaseTrapEventType Indicates the alarm type.
EntPhysicalContainedIn Indicates the parent index of the entity.
EntPhysicalName Indicates the name of the entity.
RelativeResource Indicates the part related to the alarm.
ReasonDescription 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 ReasonDescription parameter in the alarm describes the cause for the abnormal optical power.

Cause 1

Cause 1

The transmit power of the optical module exceeds the maximum value. The following is an example of the ReasonDescription parameter: ReasonDescription="Overhigh sending power of fabric module, detail information is as follows: Now power is -5.5599999; Set upper threshold is -6.3299999; Default upper threshold is 0.0000000;"

Cause 2

The transmit power of the optical module falls below the minimum value. The following is an example of the ReasonDescription parameter: ReasonDescription="Overlow sending power of fabric module, detail information is as follows: Now power is -5.5599999; Set lower threshold is -3.0000000; Default lower threshold is -12.5000000;"

Cause 3

The receive power of the optical module exceeds the maximum value. The following is an example of the ReasonDescription parameter: ReasonDescription="Overhigh receiving power of fabric module, detail information is as follows: Now power is -6.9299998; Set upper threshold is -8.9899998; Default upper threshold is 0.0000000;"

Cause 4

The receive power of the optical module falls below the minimum value. The following is an example of the ReasonDescription parameter: ReasonDescription="Overlow receiving power of fabric module, detail information is as follows: Now power is -6.9200001; Set lower threshold is -5.3200002; Default lower threshold is -16.9899998;"

NOTE:

If the interface is in shutdown, errordown, or loopback state, this alarm is not generated when the transmit power falls below the minimum value. When a link fault occurs, the interface enabled with the ALS function sends LOS signals. This alarm is not generated when the transmit power or the receive power falls below the minimum value.

Procedure

  1. Run the display transceiver verbose command to check the power of the optical module.
  2. Check whether the interface status and data forwarding are normal.

    • If so, the alarm handling ends.
    • If not, replace the optical module or collect alarm information and configuration information, and then contact technical support personnel.
