Installing An Additional Microprocessor - IBM HS21 - BladeCenter - 8853 User Manual

10. To install the DIMMs, repeat the following steps for each DIMM that you install:
11. Replace the DIMM air baffle, if one was removed from the blade server in
If you have other options to install or remove, do so now; otherwise, go to
"Completing the installation" on page 34.
If memory is installed in the Memory and I/O Expansion Blade, you can configure it
to provide memory mirroring by using the Configuration/Setup Utility program. See
Advanced Setup → Memory Settings under "Configuration/Setup Utility menu
choices" on page 40 for more information.

Installing an additional microprocessor

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
v You cannot remove the single microprocessor and replace it with a different type
v If you install a second microprocessor, you must install the same microprocessor
v Some models support dual-core processors and quad-core processors. Do not
v Always install microprocessors that have the same cache size and type, the
v Make sure that the microprocessor with the lowest feature set is the startup
v For a list of microprocessors that the blade server supports,
v Before installing a new microprocessor, download and install the most current
v The microprocessors terminate themselves; therefore, no terminator card is
v The microprocessor speeds are automatically set for this server; therefore, you
a. Turn the DIMM so that the DIMM keys align correctly with the connector on
the system board.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
b. Make sure that the small tabs on the retaining clips are in the notches on
the DIMM. If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly installed. Press the DIMM firmly into the
connector, and then press the retaining clips toward the DIMM until the
tabs are fully seated. When the DIMM is correctly installed, the retaining
clips are parallel to the sides of the DIMM.
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.
