Complete the following steps to install a pair of DIMMs:
1. Read the safety information beginning on page v and "Installation guidelines" on
2. Turn off the server and peripheral devices, and disconnect the power cords and
3. Open the retaining clip on each end of the DIMM connector.
4. Touch the static-protective package containing the DIMM to any unpainted metal
5. Turn the DIMM so that the DIMM keys align correctly with the slot.
6. Insert the DIMM into the connector.
7. Repeat steps 1 through 6 for the second DIMM; then, continue to step 8. If you

removed from the heat sink or fan sink, do not touch the thermal grease on the
bottom of the heat sink or fan sink or set down the heat sink or fan sink.
Note: Removing the heat sink or fan sink from the microprocessor destroys the
even distribution of the thermal grease and requires replacing the thermal
grease. Setting down the heat sink or fan sink on any surface when the
thermal-grease protective cover is removed will contaminate the thermal grease.
If the thermal grease becomes contaminated with particles, it must be replaced.
For information about replacing contaminated thermal grease on the heat sink,
