If the PSU does not function as expected:

■ check that all cable connections are correct and secure.

■ check that the standby switch has been pressed and is in the On position

(DC models).

■ check that the PSU is receiving the correct AC voltage (AC models).

■ if LEDs indicate a PSU fault, replace the PSU or have your authorised Allied

Telesis distributor or reseller service it.
