BASETRAP_1.3.6.1.4.1.2011.5.25.129.2.2.1 hwTempRisingAlarm

BASETRAP_1.3.6.1.4.1.2011.5.25.129.2.2.1 hwTempRisingAlarm

Description

BASETRAP/3/TEMRISING: OID [oid] Temperature exceeded the upper pre-alarm limit. (Index=[INTEGER], BaseThresholdPhyIndex=[INTEGER], ThresholdType=[ INTEGER], ThresholdIndex=[INTEGER], Severity=[INTEGER], ProbableCause=[INTEGER], EventType=[INTEGER], PhysicalName="[OCTET]", ThresholdValue=[INTEGER], ThresholdUnit=[INTEGER], ThresholdHighWarning=[INTEGER], ThresholdHighCritical=[INTEGER])

This alarm is generated when the temperature displayed on the sensor of an entity (board or its subcard) exceeds the upper threshold.

The upper threshold is determined by the hardware characteristics of the sensor.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.129.2.2.1 Minor environmentalAlarm(6)

Parameters

Name Meaning
[oid] Indicates the ID of the MIB object.
Index Indicates the index of the entity. The entity in the alarm is a board.
BaseThresholdPhyIndex Indicates the index of the entity. The entity in an alarm on temperature can be a board, fan, or power module.
ThresholdType Indicates the type of the threshold that triggers the alarm:

(1) temperatureSensor: temperature sensor

(2) humiditySensor: humidity sensor

(3) voltageSensor: voltage sensor

(4) currentSensor: current sensor

(5) powerSensor: power sensor

(6) portTraffic: traffic of the port

(7) portCrcError: CRC check of the port

(8) portBroadcast: broadcast traffic on the port

This alarm is triggered by the threshold of the temperature sensor.

Severity Indicates the severity level of the alarm.
ProbableCause Indicates the possible causes of the alarm. The code of the possible cause is as follows:

102: IANAITUPROBABLECAUSE_airConditioningFailure indicates that the fan is faulty.

EventType Indicates the alarm type:
  • communicationsAlarm (2)
  • qualityOfServiceAlarm (3)
  • processingErrorAlarm (4)
  • equipmentAlarm (5)
  • environmentalAlarm (6)

This alarm is an alarm of the environmentalAlarm type.

PhysicalName Indicates the physical name of the entity.
ThresholdIndex Indicates the subindex of the entity where the alarm is generated. A subindex identifies a temperature sensor when a board contains multiple temperature sensors.
ThresholdValue Indicates the current temperature. You can run the display temperature all command to view the temperature of the current board.
ThresholdUnit Indicates the unit of the temperature. The unit is as follows:

2: THRESHOLDUNIT_CENTIGRADE1 indicates that the temperature is expressed in centigrade.

ThresholdHighWarning Indicates the temperature threshold that triggers a minor alarm. The temperature threshold is determined by the hardware characteristics of the sensor. You can run the display temperature all command to view the threshold of the sensor on a board.
ThresholdHighCritical Indicates the temperature threshold that triggers a critical alarm. Currently, the value of this parameter is the same as the value of ThresholdHighWarning.

Impact on the System

Services on the switch 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.

Procedure

  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.
