Installing a hot-swap power supply
The following items describe the type of power supply that the server supports and
other information that you must consider when you install a power supply:
v To confirm that the server supports the power supply that you are installing, see
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.
v The server comes standard with one 550-watt or 750-watt hot-swap power
supply. The input voltage is 110 V ac or 220 V ac auto-sensing.
Note: You cannot mix 110 V ac and 220 V ac, or 550-watt and 750-watt power
supplies in the server, it is not supported.
v 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.
v The server can run fully configured with one power supply. For redundancy
support, you must install the second hot-swap power supply.
Note: You cannot mix high-efficiency and non-high-efficiency power supplies in the
server.
