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
determine the required BIOS update. The latest level of BIOS code for your
server is available from the World Wide Web. See the
User’s Guide
on the IBM
xSeries Documentation
CD for the World Wide Web addresses.
v
(Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and other options, go to http://www.ibm.com/pc/us/compat/ on
the World Wide Web.
Attention:
To ensure proper server operation when you install 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. 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
system board.
Notes:
1. To order additional microprocessor options, contact your IBM marketing
representative or authorized reseller.
2. Terminator cards are not required for empty microprocessor sockets. However,
for airflow, an empty microprocessor socket must contain a microprocessor
baffle.
3. The microprocessor speeds are automatically set for this server; therefore, you
do not need to set any microprocessor frequency-selection jumpers or switches.
4. If you need to replace a microprocessor, call for service.
5. For additional illustrations of the system-board components, see “System-board
option connectors” on page 6.
Some operating systems need to be configured to support an additional
microprocessor. See the
Option Installation Guide
on the IBM
xSeries
Documentation
CD for instructions.
