To install the replacement DIMM, complete the following steps:
1. Open the retaining clip on each end of the DIMM connector.

3. Turn the DIMM so that the DIMM keys align correctly with the slot.

4. 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 seated in the connector. 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.
5. Replace the memory card (see "Removing and replacing a memory card" on
page 124).
6. Install the top cover and lock the front cover (tower model only) (see "Replacing
the top cover, bezel, and front cover" on page 119).
7. If you disconnected any cables or power cords to replace the DIMM, connect
the cables and power cords (see "Connecting the cables" on page 116 for
cabling instructions).
8. Turn on all attached devices and the server.
