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. Firmly press one end of the DIMM into the connector; then, press the other end into the connector. 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. 9. Repeat steps 5 on page 13 through 8 to install the second DIMM of the pair. Installing a memory card Your server supports up to four memory cards. Each memory card must have at least one pair of DIMMs installed before being installed in the server. You can hot-add one memory card to each of the memory power buses, provided your operating system supports that function. At least one memory card with one pair of DIMMs must be installed in the server to operate correctly. To install a memory card, complete the following steps: 1. Read the safety information that begins on page v and "Installation guidelines" on page 7. 2. Make sure that the locking lever on the edge of the memory card is fully open, and insert the memory card into an open memory-card connector on the microprocessor board. 3. Press the memory card into the connector and close the locking levers. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 21. 14 IBM xSeries 460 Type 8872 and xSeries MXE 460 Type 8874: Installation Guide ERserver
