Installing An Additional Microprocessor - IBM 8647 - Eserver xSeries 225 Installation Manual

Installing an additional microprocessor

Your server comes with one microprocessor installed on the system board. Your
server supports up to two microprocessors. With two microprocessors, your server
can operate as a symmetric multiprocessing (SMP) server. With SMP, certain
operating systems and application programs can distribute the processing load
among the microprocessors.
Before you begin:
v Thoroughly review the documentation that comes with the microprocessor to
v (Optional) Obtain an SMP-capable operating system. For a list of supported

microprocessor, use microprocessors that have the same cache size and type, and
the same clock speed. Microprocessor internal and external clock frequencies must
be identical. You can use the Configuration/Setup Utility program in your server to
determine the specific type of microprocessor on your system board.
Important: A microprocessor must always be installed in socket CPU1 of the
