3.3 Power Supply
Installing and Removing the Power Supply
Installing the Power Supply Unit
The system can accommodate four AC or two DC power supplies in the bay at the rear of
the chassis. Each unit provides up to 1200 Watts of power.
One power supply is required for full load operation, with the other power supply purely as
a redundant, load-sharing backup. It can be removed without affecting system operation.
1. Align the power supply unit with the power supply slot. Ensure that the LED appears
on the lower right 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.

Before replacing the power supply, power off the server, unplug the power cord, and discon-
nect all wiring from the power supply.
