Run the display device command to check the switch model and status of each module on the switch.

If the power module is not faulty, go to section Contacting Technical Support Personnel.

If possible, move the problematic power module to another power slot or replace it with another power module to check whether the power module is faulty.

PWR_FAULT sensor alarm for a power module: The power module is experiencing a fan failure, output overvoltage, external short circuit, output failure, or input failure.

PWR_LACK and SWITCH_STAT sensor alarms for the same power module: The power module is present but has no power cable connected or its power switch is in OFF position.

Power is invalid for not support: An incompatible power module is installed on the switch.

If the external power supply system works properly, run the display alarm all command to check whether there are alarms about power modules of the switch.

If any of the preceding situations exists, take measures to fix the problem of the external power supply system.

Whether the input voltage measured using a multimeter was in the normal range.

Whether any power lines were aged out or loose.

Whether any high-power device was connected to the network at that time.

Whether other devices in the same rack or powered by the same power supply system were powered off.Whether any exceptions were recorded in logs of the UPS (if the switch was powered by a UPS).Whether any manual operations caused the switch to be powered off.Run the display logbuffer command to check the reboot records of the switch and confirm whether a power failure occurred around the reboot time displayed in the command output.
