Power supply
This section describes how to remove the power supply.
Removing the power supply
To remove the power supply:
1. Disconnect power from the system (see
Predisassembly procedures on page 52).
2. Remove the side access panel (see
Removing the side access panel on page 57).
3. If your workstation includes a memory riser, remove it from the chassis (see
Removing a memory
riser assembly on page 78).
4. If your workstation is equipped with high performance heatsinks, they must be removed before you
can remove the power supply. Follow the instructions in the
Removing the processor heatsink
on page 106 section to remove the high performance heatsinks.
5. To ease installation of the power supply, write down the numbers on the cables so you can easily
reconnect the cables to the correct devices.
6. Disconnect power supply cables from the system board, drives, and cards.
TIP: If your workstation does not include a memory riser, lift the memory fan to disconnect the
memory power connector on the motherboard.
