Trap Buffer Description

SRM_BASE/2/VOLTFALLINGALARM: OID 1.3.6.1.4.1.2011.5.25.129.2.2.11 Voltage exceeded the lower prealarm limit. (EntityPhysicalIndex=[ULONG], EntityPhysicalIndex=[ULONG], BaseThresholdType=3, BaseThresholdEntityPhysicalIndex=[ULONG], BaseTrapSeverity=6, BaseTrapProbableCause=73217, BaseTrapEventType=6, EntPhysicalName=[STRING], BaseThresholdValue=[ULONG], BaseThresholdUnit=5, LowCritical=[ULONG], LowWarning=[ULONG])

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

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

Impact on the System

Temporarily, services will not be interrupted but clearing this trap is urgent.

Possible Causes

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.
