To Identify a Failed Power Supply

  1. Press HOME > Status and identify which power supply is reporting a failure.
  2. Check the AC power cords for the failed Power Supply module. Ensure that they are securely plugged into the control panel power supply, as well as the power outlet.
  3. If each Power Supply is connected to a separate circuit, check that there has not been an interruption to the AC power for the failed power supply.
  4. Open the frame door and use the LEDs on the power supplies to help diagnose the failure. Refer to Control Panel Power Supply Failure for a description of the LEDs.
  5. Remove the failed power supply. Refer to To Replace a Frame Power Supply.
