Replacing a hot-swap power supply
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:
• To confirm that the server supports the power supply that you are installing, 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 standard with one of the following power supplies that connects to power supply bay 1.
The input voltage is 100-127 V ac or 200-240 V ac auto-sensing.
– 460-watt non-hot-swap power supply
– 460-watt hot-swap power supply
– 675-watt high-efficiency, hot-swap power supply
Note: You cannot mix 110 V ac and 220 V ac, or 460-watt and 675-watt power supplies in the server, it
is not supported.
• 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.
• The server supports a maximum of two hot-swap power supplies. These power supplies are designed
for parallel operation. In the event of a power-supply failure, the redundant power supply continues
to power the system.
• The server can run fully configured with one power supply. For redundancy support, you must install
the second hot-swap power supply.
