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.
