a. Turn the DIMM so that the pins align correctly with the connector.DIMM 2DIMM 3DIMM 4DIMM 1b. Insert the DIMM into the connector by pressing on one edge of the DIMMand then the other edge of the DIMM. Be sure to press straight into theconnector.Be sure that the retaining clips snap into the closed position.c. Make sure the retaining clips are in the closed position. If a gap existsbetween the DIMM and the retaining clips, the DIMM has not beenproperly installed. In this case, open the retaining clips and remove theDIMM; then, reinsert the DIMM.d. Repeat steps 4a through 4c for the second DIMM; then continue with step 5.6. If you have other options to install or remove, do so now; otherwise, go to“Installing the server cover and bezel” on page 62.Installing a microprocessorYour server comes with one microprocessor installed on the system board. If youinstall an additional microprocessor, your server can operate as a symmetricmultiprocessing (SMP) server. With SMP, certain operating systems and applicationprograms can distribute the processing load between the microprocessors.Notes:1. Before you install a new microprocessor, review the documentation that comeswith the microprocessor, so that you can determine whether you need toupdate the server basic input/output system (BIOS). The latest level of BIOSfor your server is available through the World Wide Web and the IBM BulletinBoard System (BBS). The latest level of BIOS for your server is availablethrough the World Wide Web.Installing options 55
