What to Do
Caution – The system supplies power to the motherboard even when the system is
powered off. To avoid personal injury or damage to the motherboard, you must
disconnect the AC power cords before servicing the motherboard.
1. Disengage the power supplies from the motherboard connectors.
a. Loosen the Phillips No. 2 captive screw securing the power supply to the
chassis.
Turn the screw until it stops.
b. Pull the power supply out of its bay just enough to disengage the power supply
connectors from the motherboard connectors.
Leave the power supply in its bay, but disconnected from the motherboard.
c. Repeat Step a and Step b for the other power supply.
