Installing a memory module
To install a DIMM, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 28.
2. Turn off the server and peripheral devices, and disconnect the power cords and
all external cables.
3. Remove the cover (see “Removing the top cover” on page 37).
4. Remove the air baffle (see “Removing the air baffle” on page 39).
5. Open the retaining clips on each end of the DIMM connector.

6. Touch the static-protective package that contains the DIMM to any
unpainted
metal surface on the server. Then, remove the DIMM from the package.
7. Turn the DIMM so that the DIMM keys align correctly with the slot.
8. 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.
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.
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 68.
