v Read the documentation that comes with the microprocessor to determine whether you must update the basic input/output system (BIOS) code in the server. To download the most current level of BIOS code for your server, see http://www.ibm.com/servers/eserver/support/xseries/index.html. v Obtain an SMP-capable operating system. For a list of supported operating systems, see http://www.ibm.com/servers/eserver/serverproven/compat/us/. v You can use the Configurations/Setup utility program to determine the specific type of microprocessor in the server. Microprocessor installation order The following notes describe the order in which to populate the microprocessor connectors: v For most configurations, populate the microprocessor connectors in numeric order, starting with connector 1. v If you plan to create a two-node configuration using four dual-core microprocessors, you can populate the microprocessor connectors to improve performance. The following notes describe information that you must consider when configuring the servers to use the configuration: - You must create this configuration using one System x3950 (xSeries 460) server as the primary node and one System x3950 E (xSeries 460 MXE) server as the secondary node. - Only the configuration described in these instructions is supported to improve performance. - See this section for instructions on installing a microprocessor. - See the Problem Determination and Service Guide for instructions on removing a microprocessor. - Use this configuration only with supported Windows 2003 operating systems. To configure a two-node configuration to use the four dual-core microprocessor configuration, complete the following steps. Important: The grease on the heat sink and microprocessor will remain effective when you move a microprocessor from one connector to another connector, if you observe the following precautions: v Carefully handle the heat sink and microprocessor when removing or installing these components. Do not touch the grease or otherwise allow it to become contaminated. v Because the microprocessor and heat sink are a matched set, transfer the microprocessor and heat sink from one connector to another connector one microprocessor and heat sink at a time. (This will ensure that the grease remains evenly distributed between each heat sink and microprocessor.) 1. Remove the microprocessor and heat sink installed in connector 2 of the primary node and install it in connector 1 of the secondary node. 2. Install a microprocessor and heat sink option in connector 3 of the primary node and install a VRM in VRM connector 3. 3. Install a microprocessor and heat sink option in connector 3 of the secondary node and install a VRM in VRM connector 3. Note: To install additional microprocessors in this configuration, populate connector 2; then, connector 4 in the primary node. To install additional microprocessors, populate connector 2; then, connector 4 in the secondary node. Chapter 2. Installing options 43
