| SYSTEM DESCRIPTION The Ethernet server module is a communication module that is designed to operate as a dedicated Ethernet server. The server module has two expansion slots for mounting adapter boards that handle various IO responsibilities. An Ethernet adapter board occupies one slot and provides the interface to the Ethernet network via a termination unit. The server module termination unit provides connections for Type 10BaseT (twisted pairs, Type Base (thin Ethernet, and Type 10Base5 (thick Ethernet) cable. A video adapter occupies the other expansion slot and provides the IO circuitry and connector fora VGA monitor. Although a monitor is not required to boot the Ethernet server module, one is required to use server software utilities such as the Ethernet server diagnostic utilities, and for doing offline con- figuration. The server module disk drive controller circuitry connects via a ribbon cable to the disk drive module. The hard disk drive and floppy disk drive are mounted on the disk drive module. The Ethernet server database resides on the hard disk drive. The floppy disk drive is used to load the server software and for configuration in offline mode. The Ethernet server module communicates with the INFI-NET interface modules byway of a small computer system interface (SCSI). A SCSI adapter mounts on top of the video adapter and connects to a SCSI connector module. The SCSI connector module is a paddle board that physically connects to the SCSI interface on the IMMPI01 Multi-Function Processor Interface Module via a ribbon cable. |
