Installing An Additional Microprocessor - IBM Xseries 345 8670 Maintenance Manual

Before you begin, read the documentation that comes with your option.
Complete the following steps to install a DIMM.
1. Review the information in "Safety information" on page 121, "Before you begin"
2. Turn off the server and disconnect all power cords and external cables (see
3. Locate the DIMM connectors on the system board. Determine the connectors
4. Touch the static-protective package that contains the DIMM option to any
5. To install the DIMM, repeat the following steps for each DIMM that you install:
6. If you have other options to install or remove, do so now; otherwise, go to

Installing an additional microprocessor

Your server supports up to two microprocessors. With two microprocessors, your
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 server comes with one microprocessor, you
can install a second microprocessor.
Installation guidelines:
v Thoroughly review the documentation that comes with the microprocessor, so
v (Optional) Obtain an SMP-capable operating system. For a list of supported

package.
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. Insert the DIMM by pressing the DIMM straight into the connector. Be sure
that the retaining clips snap into the closed position.
Note: If a gap exists between the DIMM and the retaining clips, the DIMM
has not been properly installed. In this case, open the retaining clips
and remove the DIMM; then, reinsert the DIMM.
