Troubleshooting PSUs

To troubleshoot power supply units (PSUs):

1. Check the status of the PSU using the Dell Storage Manager Client.
2. Determine the status of the PSU LEDs.
   • If the PSU fault indicator is lit, the PSU has failed.
   • If the Power OK LED is not lit, check the power cord and power source into which the power supply is plugged:
     • Connect another device to the power source and check whether the device works.
     • Connect the power cord to a different power source.
     • Replace the power cord.
   • If the AC fault LED is lit, this PSU is not supplying power, though the other PSU may still be supplying power.
3. Reseat the PSU by removing and reinstalling it.
   NOTE Allow several seconds for the storage system to recognize the PSU and determine its status.
