following illustration shows the microprocessor connectors and the microprocessor voltage regulator module (VRM) connectors on the microprocessor board. Note: 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. Microprocessor 3 VRM error LED Light-path diagnostics button Microprocessor 4 VRM error LED Microprocessor 3 VRM connector Microprocessor 4 VRM connector Microprocessor 1 socket Microprocessor 1 error LED Microprocessor 2 error LED Microprocessor 4 socket Light-path test LED Microprocessor 4 error LED Microprocessor 3 socket Microprocessor 2 socket Microprocessor 3 error LED v If one microprocessor is installed: - The microprocessor is installed in microprocessor connector 1 (U22). - The microprocessor supports both the startup and application processes. v If you install additional microprocessors in the server, microprocessor 2 is installed in microprocessor connector 2 (U23); microprocessor 3 is installed in connector 3 (U24); microprocessor 4 is installed in connector 4 (U25). v A new microprocessor comes in a kit with a VRM and a heat sink. The VRM is used only with microprocessor 3 or 4. v Read the documentation that comes with the microprocessor to determine whether you need to update the server basic input/output system (BIOS) code. The most current level of BIOS code for the server is available from http://www.ibm.com/pc/support. v To use SMP, obtain an SMP-capable operating system.
