Installing an additional microprocessor
The blade server comes with at least one microprocessor. If the blade server comes
with one microprocessor, you can install an additional microprocessor in the second
microprocessor socket. If an MPE is installed, the blade server must have two
microprocessors installed before the microprocessors on the MPE will become
active. Additional microprocessors can be installed in the MPE. The blade server
operates as a symmetric multiprocessing (SMP) server. With SMP, certain operating
systems and application programs can distribute the processing load between the
microprocessors.
Note: If you install an additional microprocessor, you must install the same
To use SMP, obtain an SMP-capable operating system. For a list of supported

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
