Installing a microprocessor

Your server comes with one microprocessor installed on the system board. If you
install an additional microprocessor kit, your server can operate as a symmetric
multiprocessing (SMP) server. With SMP, certain operating systems and application
programs can distribute the processing load between the microprocessors. This
enhances performance for database and point-of-sale applications, integrated
manufacturing solutions, and other applications.

Attention: To avoid damage and ensure proper server operation when you install
b. Insert the DIMM into the connector by pressing on one edge of the DIMM
and then on the other edge of the DIMM. Be sure to press straight into the
connector. Be sure that the retaining clips snap into the closed positions.
c. Make sure the retaining clips are in the closed position. If a gap exists
between the DIMM and the retaining clips, the DIMM has not been
properly installed. In this case, open the retaining clips and remove the
DIMM; then, reinsert the DIMM.

Before you install a new microprocessor, review the documentation that comes
with the microprocessor, so that you can determine whether you need to
update the server basic input/output system (BIOS). The latest level of BIOS
for your server is available through the World Wide Web.
Obtain an SMP-capable operating system (optional). For a list of supported
operating systems, see http://www.ibm.com/pc/us/compat/ on the World
Wide Web.
The microprocessor that is installed in microprocessor connector U3 is CPU 1
or processor 1. If a microprocessor is installed in microprocessor connector U17,
it is CPU 2 or processor 2. If the server has only one microprocessor installed,
that microprocessor is installed in microprocessor connector U3 and is the
startup (boot) processor. If more than one microprocessor is installed, the
microprocessor with the lower stepping level is the startup processor and the
microprocessor with the higher stepping level is the application processor. If
both microprocessors have the same stepping level, the microprocessor installed
in microprocessor connector U3 is the startup processor and the microprocessor
installed in U17 is the application processor.
Note: You can determine the stepping levels of the installed microprocessors
using the Configuration/Setup utility program.
a new or an additional 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.
