Replacing a hot-swap power supply

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

The following notes describe the type of power supply that the server supports and other information that you must consider when you install a power supply:
  • Depending on your server model, the server comes standard with one 460-watt hot-swap power supply. For redundancy support, you must install an additional hot-swap power supply, if one is not installed in your model.
  • Make sure that the devices that you are installing are supported. For a list of supported optional devices for the server, see the Lenovo ServerProven website.

To replace or install a hot-swap power supply, complete the following steps.

  1. Grasp the side clip and pull to remove the power-supply filler panel from the empty power-supply bay. Save the power-supply filler panel in case you remove the power supply at a later time.
    Important: During normal operation, each power-supply bay must contain either a power supply or power-supply filler panel for proper cooling.

  2. Slide the hot-swap power supply into the bay until the release latch clicks into place.
  3. Connect one end of the power cord for the new power supply into the ac connector on the back of the power supply; then, connect the other end of the power cord into a properly grounded electrical outlet.
  4. If the server is turned off, turn on the server.
  5. Make sure that the ac power LED on the power supply is lit, indicating that the power supply is operating correctly. If the server is turned on, make sure that the dc power LED on the power supply is lit also.

If you have replaced a server component or installed an optional device in the server, you need to reconnect the power cords and all external cables, and turn on the server and peripheral devices.
