Replacing a hot-swap ac power supply

Use this information to replace 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-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 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 750-watt and 1500-watt power supplies in the server.
• You cannot mix high-efficiency and non-high-efficiency power supplies in the server.
• 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.
CAUTION:
The power control button on the device and the power switch on the power supply do not turn off
the electrical current supplied to the device. The device also might have more than one power
cord. To remove all electrical current from the device, ensure that all power cords are disconnected
from the power source.
CAUTION:
Never remove the cover on a power supply or any part that has the following label attached.
