Installing a hot-swap power supply
Use this information to install a hot-swap power supply.
The following notes describe the type of ac power supply that the server supports and other information that
you must consider when you install a power supply:
• Make sure that the devices that you are installing are supported. For a list of supported optional devices
for the server, see http://www.lenovo.com/ serverproven/.
• Before you install an additional power supply or replace a power supply with one of
a different wattage, you may use the Power Configurator utility to determine current
system power consumption. For more information and to download the utility, go to
http://www.ibm.com/systems/bladecenter/resources/powerconfig.html.
• The server comes with one hot-swap 12-volt output power supply that connects to power supply bay 1.
The input voltage is 110 V ac or 220 V ac auto-sensing.
• Power supplies in the server must be with the same power rating or wattage to ensure that the server
will operate correctly.
• Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power
supply with the same wattage immediately.
• You can order an optional power supply for redundancy.
