ENTITYTRAP/1/ENTITYBRDTEMPALARM: OID [oid] Temperature rise over or fall below the warning alarm threshold. (Index=[INTEGER], EntityPhysicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityThresholdType=[INTEGER], EntityThresholdValue=[INTEGER], EntityThresholdCurrent=[INTEGER], EntityTrapFaultID=[INTEGER])

The temperature of the board is higher than the upper threshold.


Alarm ID Alarm Severity Alarm Type Critical environmentalAlarm(6)


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.
EntityThresholdType Indicates the threshold type of the physical entity.
EntityThresholdValue Indicates the threshold value of the physical entity.
EntityThresholdCurrent Indicates the current value of the physical entity.
EntityTrapFaultID Indicates the error code.

Impact on the System

Services on the board may be affected if the temperature becomes too high.

Possible Causes

  • The chassis is not ventilated well, which causes heat unable to be dissipated.

  • The air filter is blocked by dust.

  • Vacant slots are not covered with filler panels.

  • The ambient temperature is high.

  • There are not enough fans in the switch.

  • One or more fans in the switch have failed.


  1. Clean the air filter and remove the objects that block the air exhaust vents (if any). Cover all vacant slots with filler panels to ensure efficient heat dissipation. Then check whether the alarm is cleared.

    • If so, the alarm handling ends.
    • If not, go to step 2.

  2. Check whether the ambient temperature of the device is too high.

    • If so, go to step 3.
    • If not, go to step 4.

  3. Lower the temperature in the equipment room, and then go to step 4.
  4. Check whether fans are properly installed in all fan slots.

    • If so, go to step 6.
    • If not, go to step 5.

  5. Increase the number of fans, and then go to step 6.
  6. Run the display fan command to check the status of fans and determine whether any fan is faulty.

    • If so, go to step 7.
    • If not, go to step 8.

  7. Replace the faulty fan, and then go to step 8.
  8. After the switch has been running for a period of time, run the display temperature all command to check whether temperature of the device is still high.

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