Removing A Non-Redundant 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.
  1. Turn off the system, including any attached peripherals.
  2. Disconnect the power cable from the power source.
  3. Disconnect the power cable from the power supply and remove the straps that bundle and secure the system cables.
    • NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with the power-supply removal. For information about the cable management arm, see the system’s rack documentation.
  4. Open the system.
  5. Disconnect all the power cables from the power supply to the system board, hard drives, and optical drive.
  6. Remove the screw securing the power supply to the chassis, slide and lift the power supply out of the chassis.
