Removing the non-hot-swap power supply

When you remove or install a fixed power supply, observe the following precautions.

Statement 8

CAUTION

Never remove the cover on a power supply or any part that has the following label attached.

Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

To remove a non-hot-swap power supply on 4U server models with non-hot-swap power supplies, complete the following steps.

1. Read the safety information in Safety and Installation guidelines.
2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
3. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
   Attention

   Do not allow the server to fall over.
4. Remove the side cover (see Removing the side cover).
5. Remove the air baffle (see Removing the air baffle).
6. Disconnect the hard disk power cables from the backplate.
7. Disconnect the cables from the power supply to the system board and all internal components. Note the routing of all power-supply cables; you will need to route the power-supply cables the same way when you install the power supply.
8. While you support the power supply, remove the six 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.
   Attention

   It is important to support the power supply while you remove the mounting screws. After all six screws are removed, the power supply is loose and can damage other components in the server.
