To install a DIMM, complete the following steps:
Note: The odd-numbered DIMM connectors are white-colored, while the even-numbered DIMM connectors
are black-colored.
Step 1. Read the safety information that begins in “Safety” on page v and “Installation guidelines” on
page 36.
Step 2. Turn off the server (see “Turning off the server” on page 26) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the device.
Step 3. Remove the server top cover (see “Removing the server top cover” on page 320).
Step 4. Carefully flip 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 end 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.
Step 8. Repeat steps 5 through 7 until all the new or replacement DIMMs are installed.
Step 9. Install the air baffle (see “Replacing the air baffle” on page 323).
Step 10. Install the PCI riser-card assembly (see “Replacing a PCI riser-card assembly” on page 237).
Step 11. If you have the optional hot-swap rear hard disk drive cage installed, rotate it down (see “Rotating
the optional hot-swap rear hard disk drive cage down” on page 181).
Step 12. Replace the server top cover (see “Replacing the server top cover” on page 321).
Step 13. Reconnect the external cables; then, reconnect the power cords and turn on the peripheral devices
and the server.
Step 14. Go to the Setup utility and make sure all the installed DIMMs are present and enabled.
