Installing a memory module
Note: If you are replacing a faulty DIMM, make sure that the replacement DIMM is
the correct type of memory. If you are adding DIMMs, install the DIMMs in the
sequence shown in the following table. See the User Guide for additional
information about the type of memory that is compatible with the server.
Number of DIMMs Connectors
One DIMM 1
Two DIMMs 1, 3
Three DIMMs Not supported
Four DIMMs 1, 3, 2, 4
To install a DIMM, complete the following steps:
1. Make sure that the retaining clips on each end of the DIMM connector are fully
open.
2. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the server; then, remove the new DIMM from the package.
3. Turn the DIMM so that the DIMM keys align correctly with the connector.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
4. Insert the DIMM 2 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
1 snap into the locked position when the
DIMM is firmly seated in the connector. If there is a gap between the DIMM and
the retaining clips, the DIMM has not been correctly installed. Open the
retaining clips, remove the DIMM, and then reinsert it.
5. Reconnect any cables that you disconnected during removal.
6. Install the side cover (see “Installing the side cover” on page 63).
7. Lock the side cover if you unlocked it during removal.
8. Reconnect the external cables and power cords; then, turn on the attached
devices and turn on the server.
