Step 6 Locate the power supply ground stud (Figure 8-20). Remove the earth ground (GND) cable from the DC
power supply.
Step 7 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 8 Loosen the four 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.
Caution If you remove a power supply, the system can run for a maximum of five minutes before the system shuts
down. The fans and power elements are independent within the power supply. Therefore, it is not
required that the replacement power supply be energized within five minutes. The only requirement is
that the power supply be installed in the chassis, which energizes the fans and maintains proper system
cooling.
Step 9 Grasping the power supply handles, pull the power supply from the chassis.
