The MH4500 System is a modular, multiprocessing server based on the Intel® Pentium® II Xeon™ microprocessor. The combination of compute performance, memory capacity, and integrated input/output (I/O) provides a high performance environment for many server market applications. These range from large corporations supporting remote offices to small companies looking to obtain basic connectivity capability such as file and print services, email, web access, and web site server. As application requir

Pentium II Xeon Processor The system board supports up to four Pentium II Xeon processors, each packaged in a Single Edge Contact (S.E.C.) cartridge. The cartridge includes the processor core with an integrated 16 KB primary (L1) cache; the secondary (L2) cache; a thermal plate; and a back cover. The processor implements the MMX™ technology and the processor’s numeric coprocessor significantly increases the speed of floating-point operations. The processor external interface operates at 100 MHz.

ISA features include: bus speed up to 8.33 MHz 16-bit memory addressing Type A transfers at 5.33 MB/second Type B transfers at 8 MB/second 8- or 16-bit data transfers Plug and Play ready. The system board has two 32-bit PCI bus segments: PCI-A and PCI-B. The segments provide seven PCI connectors, three on PCI-A and four on PCI-B. PCI-A supports half-length boards only and PCI-B supports full-length boards. One of the PCI-B connectors shares a chassis expansion slot with an ISA connec

The IDE controller features: PIO and IDE DMA/bus master operations Mode 4 timings transfer rates up to 22 MB/second buffering for PCI/IDE burst transfers master/slave IDE mode. SCSI Controllers The system board contains two SCSI controllers: a narrow SCSI controller (SYM53C810AE) on the PCI-A bus, and a dual-channel wide LVD/SE (Ultra2/Ultra) SCSI controller (SYM53C896) on the PCI-B bus. The narrow controller provides support for legacy 8-bit SCSI devices in the 5 1/4-inch drive bays,

No logic, termination, or resistor loads are required to connect devices to the SCSI controller other than termination in the device at the end of the cable. The SCSI bus is terminated on the system board with active terminators that can be disabled. Video Controller The system has an onboard integrated Cirrus Logic CL-GD5480 64-bit high- performance SVGA subsystem that supports the following: BIOS compatibility with VGA, EGA, CGA, Hercules Graphics, and MDA 2 MB of 10 ns video random access

External Device Connectors The external I/O connectors provide support for a PS/2 compatible mouse and a keyboard, connector for VGA monitor, two serial port connectors, a parallel port connector, and a USB connector. System Board Management Controller (BMC) Server management is controlled by the System Board Management Controller (BMC). The BMC and associated circuits are powered from a 5Vdc standby voltage, which remains active when system power is switched off. The BMC supports the Emergency
