Adding a power supply
If you replace the power supply backplane with the power
supply backplane option, you can add a second and third
power supply, and the power supplies will be
hot-swappable. After you install a power supply, verify that
the power-supply status indicators (AC Power light and DC
Power light) are lit, indicating that the power supply is
operating properly.
Note: You do not need to turn off the power to the server
to install hot-swap power supplies.
