Replacing a memory module

Use this information to replace a memory module.

1. Read the safety information that begins on Safety and Installation guidelines.
2. Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.
3. Remove the cover (see Removing the cover).
4. Remove the air baffle (see Removing the air baffle).
5. Carefully open the retaining clips on each end of the DIMM connector and remove the DIMM.
   Attention

   To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently.

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.
7. Turn the DIMM so that the alignment slot align correctly with the alignment tab.
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 optional-device connectors for the locations of the DIMM connectors).
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.
10. Reconnect the power cords and any cables that you removed.
11. Replace the air baffle (see Replacing the air baffle).
    Note

    Close all the retaining clips even for slots without DIMMs installed before replacing the air baffle.
12. Replace the cover (see Replacing the cover).
13. Turn on the peripheral devices and the server.
