Installing an additional microprocessor The blade server comes with one or two microprocessors installed on the system board. The blade server supports two microprocessors. With two microprocessors, your blade 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 blade server comes with one microprocessor, you can install a second microprocessor. To use SMP, 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/. Attention: To ensure proper blade server operation when you install a second microprocessor, observe the following precautions: v Always install microprocessors that have the same cache size and type, the same clock speed, and identical internal and external clock frequencies (including system bus speed). v Make sure that the microprocessor with the lowest feature set is the startup (bootstrap) microprocessor, installed in the microprocessor 1 socket (U66). Notes: 1. For a list of microprocessors that are supported by your blade server, go to the ServerProven list at http://www.ibm.com/pc/us/compat/. 2. Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you have to update the blade server BIOS code. The latest level of BIOS code for your blade server is available from the World Wide Web. See Appendix A, "Getting help and technical assistance," on page 69 for the World Wide Web addresses. 3. The microprocessor sockets in this server contain built-in termination for the microprocessor bus; therefore, no terminator card is required if a second microprocessor is not installed in microprocessor socket 2. However, for proper airflow, this socket must contain a microprocessor heat-sink filler, sometimes called a microprocessor baffle. 4. The microprocessor speeds are automatically set for this server; therefore, you do not have to set any microprocessor frequency-selection jumpers or switches. The following illustration shows how to install the second microprocessor on the system board for the blade server.

Installing
an
additional
microprocessor
The
blade
server
comes
with
one
or
two
microprocessors
installed
on
the
system
board.
The
blade
server
supports
two
microprocessors.
With
two
microprocessors,
your
blade
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
blade
server
comes
with
one
microprocessor,
you
can
install
a
second
microprocessor.
To
use
SMP,
obtain
an
SMP-capable
operating
system.

operation
when

observe
the
