To install a DIMM, complete the following steps:
Step 1.
Read the safety information that begins in "Safety" on page v and "Installation guidelines" on
page 31.
Step 2.
Turn off the server (see "Turning off the server" on page 22) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the device.
Step 3.
Remove the top cover (see "Removing the server top cover" on page 188).
Step 4.
Open the retaining clip on each end of the DIMM connector.
Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and
close the clips gently.

Step 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.
Step 6.
Turn the DIMM so that the DIMM keys align correctly with the connector.
Step 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 29 for the locations
of the DIMM connectors).
Step 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.
If you have other devices to install or remove, do so now. Otherwise, go to "Completing the installation"
on page 73.
