& K D S W H USystem BoardSystem Board1-11.1 FeaturesThe M9N is a dual-processor system board that supports the IntelPentium II CPU. It contains an exclusive connector for the CPU boardthat carries two slots for the Pentium II CPU modules.This high-performance 64-bit system board utilizes both the ISA andthe PCI local bus architecture. Two ISA and five PCI bus slots resideon the board to allow installation of either master or slave devices.A 50-pin Fast SCSI-II interface and two 68-pin Wide SCSI interfacescome with the system board to connect SCSI devices. External I/Ointerfaces include a parallel port and a video port, RJ-45 and USBconnectors, and keyboard and mouse ports.The system board supports two optional features, the ASM Pro andthe remote diagnostic management (RDM), that allow better servermanagement. The ASM Pro detects problems in CPU thermalcondition, CPU working voltage detection (±12V/±5V/3.3V/1.5V), andPCI bus utilization calculation. It also detects if the CPU fan or thechassis fan malfunctions. The RDM allows execution of the RDMdiagnostic program from a remote RDM station to fix detectedproblems or to reboot the system.
