DEVM/1/hwVoltFallingAlarm_active

Message

DEVM/1/hwVoltFallingAlarm_active: Voltage exceeded the lower prealarm limit. (BaseTrapSeverity=[BaseTrapSeverity], BaseTrapProbableCause=[BaseTrapProbableCause], BaseTrapEventType=[BaseTrapEventType], EntityPhysicalIndex=[EntityPhysicalIndex], EntPhysicalName=[EntPhysicalName], BaseThresholdValue=[BaseThresholdValue], BaseThresholdUnit=[BaseThresholdUnit], LowCritical=[BaseThresholdLowCritical], LowWarning=[BaseThresholdLowWarning])

In VS mode, this log is supported only by the admin VS.

Description

The voltage of a physical entity exceeded the lower critical threshold.

Parameters

Parameter Name	Parameter Meaning
BaseTrapSeverity	Indicates the level of trap.
BaseTrapProbableCause	Indicates the possible cause of trap.
BaseTrapEventType	Indicates the type of trap.
EntityPhysicalIndex	Indicates the physical index.
EntPhysicalName	Indicates the textual name of the physical entity.
BaseThresholdValue	Indicates the actual value.
BaseThresholdUnit	Indicates the unit of the value (mV).
BaseThresholdLowCritical	Indicates the upper critical limit.
BaseThresholdLowWarning	Indicates the minor upper limit.

Possible Causes

Cause 73216:
Cause 1: The PDF power supply was insufficient.

Cause 2: The power supply module was faulty.
Cause 73217:
Cause 1: The PDF power supply was insufficient.

Cause 2: The power supply module was faulty.

Procedure

1.Run the display voltage slot slot-id command in the user view to view the voltage of each board.

2.Check whether the PDF power supply is sufficient.

If so, go to Step 4.
If not, go to Step 3.

3.Increase the PDF power supply and check whether the trap is cleared.

If so, go to Step 6.
If not, go to step 4.

4. Replace the board and check whether the trap is cleared.

If so, go to Step 6.
If not, go to Step 5.

5. Collect the trap information, log information, and configuration of the router, and contact technical support personnel.

6. End.
