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