Removing a Power Distribution Board

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.

NOTE: This system has two power distribution boards. The procedure to remove and install both the power distribution boards is similar. To access the second power distribution board at the bottom, remove the power distribution board at the top.

1Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.

2Open the system. See "Opening the System" on page 117.

3Remove the power supply. See "Removing and Installing a Power Supply" on page 85.

4Disconnect all the cables from the first power distribution board. See Figure 5-12.

Note the routing of the cable underneath the tabs on the chassis as you remove them from the system. You must route these cables properly when you replace them to prevent the cables from being pinched or crimped.

5Remove the screws securing the first power distribution board to the system. See Figure 3-24.

6Lift the power distribution board out of the system. See Figure 3-24.

NOTE: To remove the second power distribution board that is below the first power distribution board, remove the power distribution board connector and angle the board before lifting.
