Step 5. Touch the static-protective package that contains the DIMM to any unpainted metal surface on
the Flex System chassis 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.
Step 6. Make sure that both retaining clips on the DIMM connector are in the open position.
Step 7. Turn the DIMM so that the DIMM keys align correctly with the DIMM connector on the system board.
Attention: To avoid breaking the retaining clips or damaging the DIMM connector, handle the
clips gently.
Step 8. Press the DIMM into the DIMM connector. The retaining clips lock the DIMM into the connector.
Step 9. Make sure that the small tabs on the retaining clips engage 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.
