Removing a hot-swap ac power supply

Use this information to remove a hot-swap ac power supply.

Important: If the server has two power supplies, and if you remove either of them, the server will not have redundant power; if the server power load then exceeds 750W or 900W (depends on server model), the server might not start or might not function correctly.

CAUTION

The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
