Install a hot-swap power supply

Use this information to install a hot-swap power supply.

ATTENTION: Static Sensitive Device Ground package before opening

The following tips describe the type of power supply that the server supports and other information that you must consider when you install a power supply:

The standard shipping has only one power supply installed in the server. For redundancy and hot-swap support, you must install an additional hot-swap power supply. Certain customized models might be shipped with two power supplies installed.
Ensure that the devices that you are installing are supported. For a list of supported optional devices for the server, see Lenovo ServerProven website

Note

Ensure that the two power supplies installed on the server have the same wattsage.
If you are replacing the existing power supply with a new power supply of different wattsage, attach the power rating label that comes with this option onto the existing label on the top cover near the power supply.
