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 power
distribution board 2 at the bottom, remove the power distribution board at the top.
1 It is recommended to turn off the system, including any attached
peripherals, and disconnect the system from its electrical outlet.
2 Open the system. See “Opening the System” on page 151.
3 Remove the power supply. See “Removing and Installing a Power
Supply” on page 167.
4 Disconnect all the cables from the power distribution board 1. See
