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, go to

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