Installing an additional microprocessor The following notes describe the type of microprocessor that your server supports and other information that you must consider when installing a microprocessor: v 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 between the microprocessors. If your server comes with one microprocessor, you can install a second microprocessor. v You might need to update the server BIOS code. Be sure to read the documentation that comes with the microprocessor, so that you can determine whether you need to update the server BIOS code. You can download the latest level of BIOS code and many other code updates for your server at http://www.ibm.com/pc/support/ on the World Wide Web. 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. v To order additional microprocessor options, contact your IBM reseller or IBM marketing representative. v When you install the microprocessor in socket J6, you must also install the voltage regulator module (VRM) that comes with the microprocessor in VRM connector J5. v The microprocessor speeds are automatically set for this server; therefore, you do not need to set any microprocessor frequency-selection jumpers or switches. v If you need to replace a microprocessor, call for service. v If your server supports a 400 MHz front-side bus, install only a microprocessor with one pin missing from one corner and two pins missing from an adjacent corner.

Installing an additional microprocessor
The following notes describe the type of microprocessor that your server supports
and other information that you must consider when installing a microprocessor:
v
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 between the microprocessors. If your server comes with one
microprocessor, you can install a second microprocessor.
v
You might need to update the server BIOS code. Be sure to read the
documentation that comes with the microprocessor, so that you can determine
whether you need to update the server BIOS code. You can download the latest
level of BIOS code and many other code updates for your server at
http://www.ibm.com/pc/support/ on the World Wide Web.
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.
v
To order additional microprocessor options, contact your IBM reseller or IBM
marketing representative.
v
When you install the microprocessor in socket J6, you must also install the
voltage regulator module (VRM) that comes with the microprocessor in VRM
connector J5.
v
The microprocessor speeds are automatically set for this server; therefore, you
do not need to set any microprocessor frequency-selection jumpers or switches.
v
If you need to replace a microprocessor, call for service.
v
If your server supports a 400 MHz front-side bus, install only a microprocessor
with one pin missing from one corner and two pins missing from an adjacent
corner. If your server supports a 400 MHz front-side bus, the heat-sink retention
mechanism surrounding the microprocessor connector is metallic gray.
