Replacing the hot-swap power supply
This procedure applies only to the 5U server model with hot-swap power supplies.
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 430-watt hot-swap power supply. The input
voltage is 110 V ac or 220 V ac auto-sensing.
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.
