5. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the outside of the server. Then, remove the DIMM from the
package.
6. Turn the DIMM so that the DIMM keys align correctly with the connector.
7. Insert the DIMM into the connector by aligning the edges of the DIMM with
the slots at the ends of the DIMM connector (see "System-board optional device
connectors" on page 42 for the locations of the DIMM connectors).
8. 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.
Note: 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.
