Use this information to install 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 install a hot-swap power supply, complete the following
steps.
- 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.
Figure 1. Hot-swap power supply installation
- Slide the hot-swap power supply into the bay until the
release latch clicks into place.
- 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.
- 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 correctly. If the
server is turned on, make sure that the dc power LED on the power
supply is lit also.
If you have other devices to install, do so now.
