Figure 164. Hot-swap power supply removal
After removing the power supply:
1. Install a new power supply or install the power-supply filler to cover the power supply bay. See “Install a
hot-swap power supply” on page 179.
Important: To ensure proper cooling during normal server operation, both of the power supply bays
must be occupied. This means that each bay must have a power supply installed; or one has a power
supply installed and the other has a power supply filler installed.
2. If you are instructed to return the old hot-swap power supply, follow all packaging instructions and use
any packaging materials that are provided.

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

Notes:
• Ensure that the two power supplies installed on the server have the same wattsage.
