3.3 Power Supply

The system can accommodate two AC or two DC power supplies in the bay at the rear of
the chassis. Each unit provides up to 650 Watts of power. Only a single power supply is
required for operation, with the second power supply purely as a redundant, load-sharing
backup. It can be removed without affecting system operation.
Installing and Removing the Power Supply
1.
Align the power supply unit with the power supply slot. Ensure that the LED appears
on the left when you are installing the power supply unit.
2.
Carefully slide the PSU all the way into the power supply bay until it clicks into place.
