3. Connect the light path diagnostics ribbon cable to the I/O board. 4. Replace the bezel and top cover. 5. Reconnect the external cables and power cords. Microprocessor tray and microprocessor The following sections describe how to replace the microprocessor tray and a microprocessor. The following notes describe information that you must consider when installing a microprocessor: v The voltage regulators for microprocessors 1 and 2 are integrated on the microprocessor board; the VRMs for microprocessors 3 and 4 come with the microprocessor options and must be installed on the microprocessor board. v When installing additional microprocessors, populate the microprocessor connectors in numeric order, starting with connector 2. If you install the microprocessors in the wrong order, the server will not turn on. v You can use the Configurations/Setup utility program to determine the specific type of microprocessor in the server. v Install an IBM xSeries Dual-Core X3 Upgrade Option kit to enable the server to support dual-core microprocessors. Important: The following minimum code levels must be installed for the server to support the dual-core upgrade: - Basic input/output system (BIOS) version 1.07, level 45A - Remote Supervisory Adapter II (RSA2) version 1.05, level 30A - Baseboard management controller code (BMC) version 1.18, level 34A - Complex programmable logic device (CPLD) version 1.03, level 10A - Diagnostic program (Diags) version 1.03, level 20A The server model number will change when you install this upgrade. A new label comes with the option kit for you to place over the existing label on the server. The following table lists the kit server model numbers before and after the dual-core upgrade is installed. Table 7. Model numbers before the dual-core upgrade is installed 3Rx 4RX Model numbers after the dual-core upgrade is installed ZZZ 333 Removing and installing a microprocessor Complete the following steps to remove the microprocessor tray and a microprocessor. 124 IBM xSeries 366 Type 8863: Problem Determination and Service Guide
