c. Using a screwdriver, secure the heat sink to the microprocessor socket on the SMP board using the two captive mounting screws. Press firmly on the screws and tighten them, alternating between them. Do not overtighten the screws. 11. Close the SMP Expansion Module top cover; then, install the module in the server. For details, see "Reinstalling an SMP Expansion Module and cover" on page 23. 12. If you have other options to install or remove, do so now. 13. Close the cover on the server; then, install the server in the rack cabinet and connect all external cables. For details, see "Installing the server in the rack cabinet" on page 33. 14. Turn on the server. When you install or remove microprocessors, the server configuration information changes. Therefore, you must change and save the new configuration information by using the Configuration/Setup Utility program. See the User's Guide on the IBM xSeries Documentation CD. Important: If your server will not start after replacing or installing a microprocessor, you might have installed a microprocessor in the wrong socket or installed a microprocessor of a different type, or the VRM is not seated properly. Ensure that you have installed the microprocessor in the correct location and that it is of the same type. Also ensure that the VRM is properly seated in the slot. Installing a memory module The following notes describe the types of dual inline memory modules (DIMMs) that your server supports and other information that you must consider when installing DIMMs: v IBM periodically makes updates available to provide enhancements to the standard features of your server. Currently, your server supports the memory mirroring and Memory ProteXion features of the Active Memory technology. Be sure to check the IBM support Web site occasionally to ensure that you have the most current levels of system software installed. v To use the hot-add and hot-swap memory features, you must reconfigure your server using the Configuration/Setup Utility program. See the User's Guide on the IBM xSeries Documentation CD for additional information. Note: The server must have a minimum of 4 GB of memory installed before you can configure the hot-add memory feature. v Your server operates with a minimum of two 512 MB DIMMs installed in slots 1 and 3 in the SMP Expansion Module. When installing or removing DIMMs, you must install or remove the DIMMs two at a time and in the order described in this section. v Use the instructions in "Installing DIMMs" on page 21 to help maintain performance. See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory modules for use with your server. Note: For optimum performance, balance the amount of memory between the two ports.
