Installing a 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 power supply:
v The server comes standard with one 1100-watt hot-swap power supply for a
v If the maximum load on the server is more than 935 watts or if a problem occurs
two-microprocessor configuration or two 1100-watt hot-swap power supplies for a
four-microprocessor configuration.
with one of the power supplies, the redundant power supply can meet the power
requirements.
To provide redundant power capabilities in the server:
– install two power supplies in a server with two microprocessors or more
microprocessors (less than 80W).
– install three power supplies in a server with four microprocessors (greater
than 80W).
Notes:
1. In a server with two-microprocessor configuration, two power supplies must
be installed in the server for either power supply to be considered hot-swap.
If the server comes with four microprocessors, three power supplies must be
installed in the server for a power supply to be considered hot-swap.
2. The IBM Power Configurator detects your server power consumption and
helps you determine whether an additional power supply is required before
you install more components in the server. You can download a free copy of
