■ Gather necessary tools and equipment.

You will need an appropriate flat-bladed or Phillips (#1) screwdriver to tighten

or loosen the captive screws.

Caution Follow correct anti-static procedures. Failure to do so could

damage the PSU, fan, or switch. If you are unsure about correct procedures,

contact your authorised Allied Telesis distributor or reseller.

Caution Keep your hands and fingers out of the power supply bays.

To remove a PSU, chassis fan module or FOM

1. If you are removing a PSU, disconnect the power supply.

For AC PSUs, turn off the main power source to the PSU and disconnect

the power cord.

For PWR01 DC PSUs, push and release the Run/Standby switch to the

Standby (off) position using a small pin. The Run/Standby switch is in the

Run (on) position when it is depressed, and in the Standby (off) position

when it is not depressed. Disconnect the supply cable wires from the

circuit breaker.

For PWR05 DC PSUs, slide the Run/Standby switch to the O (off) position.

Disconnect the power supply cable from the power supply.

2. Using a screwdriver, loosen the captive screws until fully loosened.
