Removing the Power Supply

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

1Turn off the system and all attached peripherals.

2Disconnect the power cable from the power source.

NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power-supply removal. For information about the cable management arm, see the system’s rack documentation.

3Open the system. See "Opening the System" on page 50.

4Disconnect all the power cables from the power supply to the system board, hard drive(s), and optical drive. See Figure 3-18.

Note the routing of the power cables as you remove them from the system board and drives. You must route these cables properly when you replace them to prevent them from being pinched or crimped.
