  • Page 13: Board Characteristics

    PCI is a high-speed standard local bus for interfacing a number of I/O components to the processor and memory subsystem in a high end PC. The PCI functionality for the LSI22910 is contained within the LSI Logic LSI53C896 PCI to SCSI I/O Processor chip. The LSI53C896 connects directly to the PCI bus and generates timing protocol in compliance with the PCI Local Bus Specification Revision 2.1 standard.

  • Page 23: Connecting The Scsi Peripherals

    2.2.3 Connecting the SCSI Peripherals All internal SCSI bus connections to the LSI22910 are made with an unshielded, 68-conductor ribbon cable (see Figure 2.3). One side of this cable is marked with a color to indicate the pin-1 side. The connectors on this cable are keyed to ensure proper pin-1 connection.

  • Page 24: Making Internal Scsi Bus Connections

    Step 1. To connect an internal SCSI device, plug the 68-pin connector on one end of a wide internal SCSI ribbon cable into the connector J4 or J5. See the example in Figure 2.4. Figure 2.4 Internal SCSI Ribbon Cable to Host Adapter Installing the LSI22910...
