DIMM Retaining clip 8. Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of the DIMM connector. 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 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. 10. Repeat steps 6 through 10 to replace any remaining DIMMs on the memory card. 11. Replace the memory card: a. Insert the memory card into the memory card connector. b. Press the memory card into the connector and close the small retention lever. c. Wait two seconds and close the large retention lever. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 49. Hot-adding DIMMs and memory cards To hot-add DIMMs and memory cards, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 21. Attention: Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which could result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when working inside the server with the power on. 2. Remove the front cover (tower model only), and the top cover (see "Removing the front cover, top cover, and bezel" on page 23). Attention: When moving the memory card, do not allow it to touch any components or structures inside the server. 3. Place a memory card on a flat, static-protected surface with the DIMM connectors facing up. Attention: To avoid breaking the DIMM retaining clips or damaging the DIMM connectors, open and close the clips gently. 4. Open the retaining clip on each end of the DIMM connector. Chapter 2.
