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/

The server comes with one hot-swap 12-volt output power supply that connects
to power supply bay 1. The input voltage is 100-127 V ac or 200-240 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. For example, you cannot mix
550-watt and 750-watt power supplies in the server.
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.
