Installing a hot-swap dc power supply
Observe the following precautions when you 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.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.
