Step 5 Locate the power supply ground stud (Figure 8-20). Remove the earth ground (GND) cable from the DC
power supply.
Step 6 Loosen and remove the Kepnut screw, washer, and ground lug in that order.
Warning When installing the unit, the ground connection must always be made first and disconnected last.
Step 7 Loosen the captive screws on the DC power supply.
Note Two power supplies must be installed in the chassis at all times to ensure sufficient cooling. The
system fans are inside the power supply units and must spin for cooling. Because all the system
fans can be powered by one power supply, the second power supply unit does not have to be
powered on, but it must be installed.
