Installing a hot-swap power supply

Use this information to install a hot-swap power supply.
Before you begin
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:
v Make sure that the devices that you are installing are supported. For a list of
supported optional devices for the server, see http://www.ibm.com/systems/
info/x86servers/serverproven/compat/us.
v Before you install an additional power supply or replace a power supply with
one of a different wattage, you may use the IBM 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.
v 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.
v Power supplies in the server must be with the same power rating or wattage to
ensure that the server will operate correctly.
v 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.
v You can order an optional power supply for redundancy.
v 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 supports a maximum of two power supplies.
