8. Turn the DIMM so that the DIMM keys align correctly with the slot. DIMM Retaining clip 9. Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of the DIMM connector. 10. 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. 11. Repeat steps 6 through 10 to install the second DIMM in the pair and for each additional pair that you install. 12. 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 retention levers. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 49. Hot-swapping DIMMs To hot-swap DIMMs, 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. Make sure that the memory hot-swap enabled LED is lit. Chapter 2.
