Installing a hot-swap dc power supply
Use this information to install a hot-swap dc 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-03.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 -48 V dc or -60 V dc auto-sensing.
• Before you install a dc power supply in the server, you must remove all ac power supplies. Do not use
both ac and dc power supplies in the same server. Install up to two dc power supplies or up to two ac
power supplies, but not a combination.
• 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.
