Removing a non-hot-swap power supply

To remove a non-hot-swap power supply, complete the following steps:
1. Read the safety information that begins on page "Important Safety Information" on page 1.
2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
3. Unlock and remove the side cover (see "Removing the side cover" on page 142).
Note: It might be helpful to lay the server on its side for the remainder of this procedure.
4. Disconnect the cables from the power supply to the system board and all internal components.
Attention: Support the power supply while you remove the mounting screws. After the screws are
removed, the power supply is loose and can damage other components in the server.
5. While you support the power supply, remove the four screws that secure it to the chassis; then, lift the
power supply out of the chassis. Save the screws to use when you install the replacement power supply.
