SRM/3/POWERVOLTAGELOW

Message

SRM/3/POWERVOLTAGELOW:Power supply input voltage in slot [ULONG] subcard [STRING] is lower than the threshold, or there is no input voltage.

The AC power input of the system power is in undervoltage or abnormal state.

Parameter Name	Parameter Meaning
slot [ULONG]	Indicates the slot ID of the power supply unit.
subcard [STRING]	Indicates the subcard ID of the power supply unit.

Cause 1: The power switch is turned off.

Cause 2: The power module is not connected to the external power cable.

Cause 3: The external power voltage of system power modules does not meet input voltage requirements.

Turn on the power switch and ensure that the power module connects to the external power cable correctly. Check whether this log is cleared.
If so, the log handling process is complete.

If not, go to step 2.
Check whether the external power voltage of system power modules meets input voltage requirements.
If not, contact professional circuit personnel to check whether the power line is normal.

If so, go to step 3.
Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
