Accessing Components Behind the Power Supply
To access the processors and DIMMs, disengage the locking plungers, and swing the hinged
power supply out of the chassis. Or, you can remove the power supply entirely. However,
you need not remove the power supply for most routine service or upgrade tasks. As needed,
you may want to disconnect power supply cables to peripheral devices to swing the power
supply out fully.
See Chapter 2, “Servicing the System,” for complete details on removing the power supply.
To access components behind the power supply:
1. Unplug the AC power cord from the rear of the unit.
2. Remove the top cover and left side panel. See the previous section for details.
3. Grasp both knurled plungers on the power supply, pull them toward each other, and then
swing the power supply toward you.

Disconnect power cables to internal devices as needed to allow the power supply to swing out
fully.

To stow the power supply:
1. Reconnect any power cables that you disconnected.
