Troubleshooting
If the PSU does not function as expected:

■ On the PWR01 DC model, check that the Run/Standby switch has been
pressed and is in the On position.
■ On the PWR05, check that the Run/Standby switch has been set to Run
(position 1).
■ Check that the PSU is receiving the correct AC voltage (AC models).
■ Check that the PSU is receiving the correct DC voltage (DC models).
■ If LEDs indicate a PSU fault, replace the PSU or have your authorised Allied
Telesis distributor or reseller service it.
