v When you restart the server after you add or remove a DIMM, a message is displayed indicating that the memory configuration has changed. To remove a DIMM, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 20. 2. Turn off the server and peripheral devices, and disconnect the power cord and all external cables. Remove the cover (see "Removing the cover" on page 22). Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently. 3. Open the retaining clip on each end of the DIMM connector. 4. Lift the DIMM out of the connector. To install a DIMM, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 20. 2. Turn off the server and peripheral devices, and disconnect the power cord and all external cables. Remove the cover (see "Removing the cover" on page 22). Attention: To avoid breaking the retaining clips or damaging the DIMM connectors, open and close the clips gently. 3. Open the retaining clip on each end of the DIMM connector. 4. Touch the static-protective package that contains the DIMM to any unpainted metal surface on the server. Then, remove the DIMM from the package. 5. Turn the DIMM so that the DIMM keys align correctly with the connector. 6. Insert the DIMM 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 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 inserted; open the retaining clips, remove the DIMM, and then reinsert it. If you have other devices to install or remove, do so now. Otherwise, go to "Completing the installation" on page 38. Chapter 2. Installing optional devices 37
