Replacing a memory module
Use this information to replace a memory module.
To install a memory module, complete the following steps:
Step 1. Read the safety information that begins on “Safety” on page v and “Installation guidelines” on
page 116.
Step 2. Turn off the server and peripheral devices and disconnect the power cords and all external cables,
if necessary.
Step 3. Remove the cover (see “Removing the cover” on page 119).
Step 4. Remove the air baffle (see “Removing the air baffle” on page 122).
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. Carefully open the retaining clips on each end of the DIMM connector.

Step 7. Turn the DIMM so that the alignment slot aligns correctly with the alignment tab.
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 26 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.
Step 10. Reconnect the power cords and any cables that you removed.
Step 11. Replace the air baffle (see “Replacing the air baffle” on page 122).
Note: Close all the retaining clips even for slots without DIMMs installed before replacing the
air baffle.
