Installing An Additional Microprocessor - IBM LS42 - BladeCenter - 7902 Installation And User Manual

7. Repeat the following steps for each DIMM that you install:

Installing an additional microprocessor

The blade server comes with at least one microprocessor. If the blade server comes
with one microprocessor, you can install an additional microprocessor in the second
microprocessor socket. If an MPE unit is installed, additional microprocessors can
be installed in the MPE unit. The blade server must have two microprocessors
installed for the microprocessors in the MPE to become active. The blade server
operates as a symmetric multiprocessing (SMP) server, regardless of how many
microprocessors are installed. With SMP, certain operating systems and application
programs can distribute the processing load among the microprocessors.
The following illustration shows how to install a DIMM in a blade server. This
illustration also applies to installing or removing DIMM filler.
a. Locate the DIMM connectors (see "Blade server connectors" on page 14).
Determine the connector into which you will install the DIMM.
b. Remove the DIMM filler from the DIMM connector.
Note: A DIMM or DIMM filler must occupy each DIMM socket.
c. Make sure that both retaining clips on the DIMM connector in which you will
install the DIMM are fully open.
d. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the BladeCenter unit or any unpainted metal surface on
any other grounded rack component in the rack in which you are installing
the DIMM for at least 2 seconds; then, remove the DIMM from its package.
e. 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.
f. Carefully insert the DIMM straight down into the connector using the
retaining clip slots as guides to align the DIMM with the connector.
g. Simultaneously press down firmly and evenly on both ends of the DIMM
until it is completely seated in 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.
