Complete the following steps to install a DIMM:
DIMM
Retaining clip
1. Read the documentation that comes with the DIMM.
2. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs.
3. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the BladeCenter unit or any unpainted surface on any other
grounded rack component for at least 2 seconds. Then, remove the DIMM from
the package.
4. Make sure that both of the connector retaining clips are in the fully open
position.
5. Turn the DIMM so that the DIMM keys align correctly with the connector on the
system board.
Attention: To avoid breaking the DIMM retaining clips or damaging the DIMM
connectors, open and close the clips gently.
6. Insert the DIMM by pressing the DIMM along the guides into the connector.
Make sure that the retaining clips snap into the closed positions.
Attention: 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.
7. Install the blade server cover (see “Installing the blade server cover” on page
60).
8. Install the blade server into the BladeCenter unit (see “Installing the blade
server in a BladeCenter unit” on page 58).
