Installing a 1400-watt or 900-watt hot-swap 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 hot-swap 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 900-watt (input voltage 110 or 220 V ac
auto-sensing) hot-swap power supply or one 1400-watt hot-swap power supply
(input voltage 110 or 220 V ac auto-sensing) depending on your model.
Note:
Do not mix 110 V ac and 220 V ac input voltage power supplies in the
server. It is not supported.
v
Do not mix 900-watt and 1400-watt power supplies in the server. It is not

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
Full N+N redundacy support is provided by two 1400-watt power supplies fed
from a 220 V input source.
v
Limited N+N redundancy support is provided by two 900-watt power supplies
fed from either a 110 V or 220 V input source, or by two 1400-watt power
supplies fed from a 110 V source.
v
For the server to support two power supplies, you must install the optional IBM
Power Interposer for Redundant Power option or the optional IBM
