IBM® Netfinity® 4500R User’s Reference
Installing a microprocessor
multiprocessing (SMP) server. With SMP, certain operating systems and application
programs can distribute the processing load between the microprocessors.
Notes:
1. 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 and the IBM Bulletin Board
System (BBS). Refer to “Getting help, service, and information” on page 157 for
the appropriate World Wide Web addresses and bulletin-board telephone
numbers.
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.
3. Your server comes with one microprocessor installed in the microprocessor
connector that is farther away from the memory slots (connector U3). This is the
startup (boot) microprocessor. A microprocessor installed in connector U17 is
microprocessor 2. If more than one microprocessor is installed, the
microprocessor installed in connector U17 is the startup processor and the
microprocessor installed in U3 is the application processor.
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.
