supply
When the hot-swap power supply backplane is installed, you can replace the 385-watt
power-supply with an optional backplane that will enable you to install up to three
power supplies, which enables redundancy and will make the power supplies 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.
Notes:

You do not need to turn off the power to the server to install hot-swap power
