Step 5
Locate the power supply ground stud (see xref fig). Remove the ground (GND) cable from the DC power supply.
Step 6
Loosen and remove the Kepnut screw, washer, and ground lug in that order.
When installing the unit, the ground connection must always be made first and disconnected
last.
Warning
Step 7
Loosen the captive screws on the DC power supply.
Four power supplies must be installed in the chassis at all times, with a minimum of two power supplies (one
per zone) connected to the mains in order to power on the system and 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 must be connected.
