Step 2. Turn off the server (see "Turning off the server" on page 24) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the
device.
Step 3. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
Attention: Do not allow the server to fall over.
Step 4. Unlock and remove the left-side cover (see "Removing the left-side cover" on page 193).
Step 5. 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 6. 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 7. Turn the DIMM so that the DIMM keys align correctly with the connector.
Step 8. 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 internal connectors" on page 29 for the locations of the
DIMM connectors).
Step 9. 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 85.
