Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, handle the clips gently. b. Insert the DIMM by pressing the DIMM along the guides into the connector. Make sure that the retaining clips snap into the closed positions. Important: If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly installed. In this case, open the retaining clips and remove the DIMM; then, reinsert the DIMM. 9. Before closing the I/O tray, check that all components are installed and seated correctly and that you have not left loose tools or parts inside the blade server. Pivot the I/O tray to the closed position until it clicks into place. 10. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 62. Installing an additional microprocessor The following notes describe the type of microprocessor that your blade server supports and other information that you must consider when installing a microprocessor: v Your blade server supports up to four microprocessors. With two or four microprocessors, your blade server can operate as a symmetric multiprocessing (SMP) server. With one or three microprocessors, the blade server will not operate as an SMP server; however, installing more than one microprocessor will still result in improved server performance, even if the blade server is not configured for SMP operation. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. 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 server operation when you install an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Internal and external clock frequencies of all microprocessors installed in the server must be identical (including system bus speed). v For a list of microprocessors supported by your blade server, go to the ServerProven® list at http://www.ibm.com/pc/us/compat/. v Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you need 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 107 for the World Wide Web addresses. v The microprocessor sockets in this blade server contain built-in termination for the microprocessor bus; therefore, terminator cards are not required for empty microprocessor sockets. However, for proper airflow, an empty microprocessor socket must contain a microprocessor heat-sink filler, sometimes called a microprocessor baffle. v The microprocessor speeds are automatically set for this blade server; therefore, you do not need to set any microprocessor frequency-selection jumpers or switches. 46 BladeCenter HS40 Type 8839: Hardware Maintenance Manual and Troubleshooting Guide

Installing
an
additional

The
following
notes
describe

that

blade
server
supports
and
other
information
that
you
must
consider
when
installing

to
four
microprocessors.
With
two
or
four
microprocessors,
your
blade
server
can
operate
as
a
symmetric
multiprocessing
(SMP)
server.
With
one
or
three
microprocessors,
the
blade
server
will
not
operate
as
an
SMP
server;
however,
installing
more
than
one
microprocessor
will
still

in
improved
server
performance,
even
if
the
blade
server
is
not
configured
for
SMP
operation.
With
SMP,
certain
operating
systems
and
application
programs
can
distribute
the
processing
load
between
the
microprocessors.
To
use
SMP,
obtain
an
SMP-capable
operating
system.
