Power Supply - ASROCK Barebone 2U12L6SW User Manual

3.4 Power Supply

1. Before replacing the power supply, power off the server, unplug the power cord, and
disconnect all wiring from the power supply.
2. In a redundant system, you do not need to power down the server.
Replacing the Power Supply Unit
The 2U12L6SW 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.
1. Align the power supply unit with the power supply slot. Ensure that the three LEDs
appear on the 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.
