What to Do
Caution – Be sure that all AC power cords are disconnected from the back of the
system before performing this procedure. Attempting to replace the power
distribution board while the AC power cord is plugged in to a power source can
result in serious personal injury.
1. Position the power distribution board in the chassis floor.
You may need to adjust the cable attached to the center AC power connector
assembly so that it does not interfere with the positioning of the power distribution
board.
2. Insert the power supply connectors into their slots in the chassis.
