Installing a hot-swap ac power supply
Use this information to install a hot-swap ac 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:
• 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 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.
• 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.
