Notes:
1. Thoroughly 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) code. The latest level of BIOS code for the server is
available through the World Wide Web. Go to
http://www.pc.ibm.com/support/, select IBM Servers, and make the selections
for your server.
2. 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.
Attention: To avoid damage and ensure proper server operation when you
install 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.
3. To order additional microprocessor options, contact your IBM reseller or IBM
marketing representative.
4. If you replace the microprocessor in the server with a microprocessor that
operates at a different speed, be sure to set the microprocessor core-frequency-
selection jumpers correctly. See Table 8 on page 73.
5. Your server comes standard with one microprocessor installed. The
microprocessor is installed in microprocessor connector J2 and is the startup
(boot) processor. A microprocessor installed in microprocessor connector J3 is
processor 2; a microprocessor installed in microprocessor connector J4 is
processor 3; a microprocessor installed in microprocessor connector J5 is
processor 4. If more than one microprocessor is installed, the highest numbered
processor is the one the server will start from. The lower numbered
microprocessors are used as application processors.
The following table and the label on the inside of the top cover of the server show the
order in which additional microprocessors and voltage regulator modules (VRMs)
must be installed.
