IBM E Server x336 Series, Option Installation Manual, Page: 45 / 76

Attention:
v Avoid touching the components and gold-edge connectors on the DIMMs.
Make sure that the DIMMs are completely and correctly seated in the slots.
Incomplete insertion might cause damage to the system board or to the
DIMMs.
v
When you handle static-sensitive devices, take precautions to avoid damage
from static electricity. For information about handling these devices, see
“Handling static-sensitive devices” on page 14.
v
To avoid breaking the retaining clips or damaging the DIMM slots, open and
close the clips gently. Do not force the DIMM into the slot.
3. Open the retaining clip on each end of the DIMM connector.
4. Touch the static-protective package containing the DIMM to any unpainted metal
surface on the server; then, remove the DIMM from the package.
5. Turn the DIMM so that the DIMM keys align correctly with the slot.
6. Install the DIMM in the slot. Firmly press the DIMM straight down into the
connector by applying pressure on both ends of the DIMM simultaneously. The
retaining clips snap into the locked position when the DIMM is firmly seated in
the connector. If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly inserted; open the retaining clips, remove the
DIMM, and then reinsert it.
7. If you have other options to install or remove, do so now.
8. Go to “Completing the installation” on page 44.
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 The server supports up to two microprocessors (two-way support); the IBM
xSeries 336 server comes with one Xeon microprocessor installed. With two
microprocessors, the server can operate as a symmetric multiprocessing (SMP)
server.
With SMP, application programs can distribute the processing load between the
microprocessors. This enhances performance for database and point-of-sale
applications, integrated manufacturing solutions, and other applications.
