BASETRAP/4/VOLTFALLINGRESUME: OID [oid] Voltage recovered to the normal range and the low voltage alarm was cleared. (Index=[INTEGER], BaseThresholdPhyIndex=[INTEGER], ThresholdType=[INTEGER], ThresholdIndex=[INTEGER], Severity=[INTEGER], ProbableCause=[INTEGER],EventType=[INTEGER], PhysicalName="[OCTET]", ThresholdValue=[INTEGER], ThresholdUnit=[INTEGER], ThresholdLowWarning=[INTEGER], ThresholdLowCritical=[INTEGER])

The voltage increased to the normal range, and the low voltage alarm was cleared.


Alarm ID Alarm Severity Alarm Type Warning environmentalAlarm(6)


Name Meaning
[oid] Indicates the ID of the MIB object.
Index Indicates the index of the entity. The entity in the voltage alarm can be a board, a fan, or a power module.
BaseThresholdPhyIndex Indicates the index of the entity. The entity in an alarm on voltage can be a board, a fan, or a power module.
ThresholdType Indicates the object that triggers the alarm. The objects are as follows:

(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 of the port

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

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

116: IANAITUPROBABLECAUSE_rectifierLowFVoltage indicates that the low voltage is adjusted.

EventType Indicates the alarm type. Alarms are classified into the following types:
  • communicationsAlarm (2): alarm for communication problems
  • qualityOfServiceAlarm (3): alarm for service quality
  • processingErrorAlarm (4): alarm for processing errors
  • equipmentAlarm (5): alarm for the equipment
  • environmentalAlarm (6): alarm for the environment

This alarm is of the environmentalAlarm type, that is, the alarm on environment errors.

PhysicalName Indicates the physical name of the entity.
ThresholdIndex Indicates the sub-index of the entity where the alarm is generated. A sub-index identifies a voltage sensor when a board contains multiple voltage sensors.
ThresholdValue Indicates the current voltage. You can run the display voltageall command to view the current voltage of the board and the voltage threshold.
ThresholdUnit Indicates the unit of the voltage. The unit is as follows:

4: THRESHOLDUNIT_VOLTAGE1 indicates that the unit is V.

ThresholdLowWarning Indicates the voltage threshold that triggers a minor alarm. The voltage threshold is determined by the hardware feature of the sensor. You can run the display voltageall command to view the threshold of the sensor on a board.
ThresholdLowCritical Indicates the voltage threshold that triggers a critical alarm. Currently, the value of this parameter is the same as the value of ThresholdHighWarning.

Impact on the System


Possible Causes

The power module is restored and the voltage of the board has increased to the normal range.
