Installing a hot-swap power supply

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:

• For 460-watt power-supply server models, the standard shipping has only one 460-watt power supply installed in the server. For redundancy and hot-swap support, you must install an additional 460-watt hot-swap power supply. Certain customized models might be shipped with two power supplies installed.
• Make sure that the devices that you are installing are supported. For a list of supported optional devices for the server, go to the Lenovo ServerProven website.

CAUTION

Never remove the cover on a power supply or any part that has the following label attached.

Hazardous voltage, current, and energy levels are present inside any component that has this label attached. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.

To install a hot-swap power supply, do the following:

1. Remove the power-supply filler. Then, slide the hot-swap power supply into the bay until the release latch clicks into place.
   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. Connect one end of the power cord to the new power supply connector; then, connect the other end of the power cord into a properly grounded electrical outlet.
3. If the server is turned off, turn on the server. Make sure that the ac power LED on the power supply is lit, indicating that the power supply is operating properly. If the server is turned on, make sure that the dc power LED on the power supply is lit also.
