Installing an additional microprocessor
Your server comes with one or two microprocessors 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. If your server comes with one microprocessor, you can
install a second microprocessor.
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 through the World Wide Web (see “Recovering the BIOS
code” on page 36).
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.
For a list of microprocessors supported by your server, see the ServerProven
®
list
at http://www.ibm.com/pc/us/compat/ on the World Wide Web.
Important:
A boot processor must always be installed in socket U13 of the system
board.
Notes:
1. To order additional microprocessor options, contact your IBM reseller or IBM
marketing representative.
2. When you install a microprocessor in socket U9, you must also install the
voltage regulator module (VRM) that comes with the microprocessor, in VRM
connector J1.
3. The microprocessor sockets in this server contain built-in termination for the
microprocessor bus; therefore, terminator cards are not required for empty
microprocessor sockets. However, for airflow, an empty microprocessor socket
must contain a microprocessor baffle.
4. The microprocessor speeds are automatically set for this server; therefore, you
do not need to set any microprocessor frequency-selection jumpers or switches.
5. If you need to remove a microprocessor, see “Microprocessor removal” on
page 113.
