Note: DIMM connectors 3, 6, 7, 10, 15, 18, 19, and 22 are not used in memory rank
sparing mode when UDIMMs are installed in the server.
1. If riser-card assembly 1 contains one or more adapters, remove riser-card
assembly 1.
2. Remove the DIMM air baffle.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
3. Open the retaining clip on each end of the DIMM connector.
4. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the server. Then, remove the DIMM from the package.
5. Turn the DIMM so that the DIMM keys align correctly with the connector.
6. Insert the DIMM into the connector by aligning the edges of the DIMM with the
slots at the ends of the DIMM connector. 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.
Attention: 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.
7. Repeat steps 1 through 6 until all the new or replacement DIMMs are installed.
