The Silicon Graphics® PCI (Peripheral Component Interconnect) SCSI option board provides one SCSI (small computer systems interface) port for qualified servers and graphics workstations in the Origin™ family, such as Origin200™ and OCTANE™ workstations. The board is available in two versions:
single-ended (marketing code PCI-SCSI-Q-SE-1P, part number 9980983)
differential (marketing code PCI-SCSIB-Q-DF-1P, part number 9980984)
In each case, the board's connector is standard Fast-20, affording connectivity to a wide range of SCSI peripheral devices.
This guide is written for owners and users of the PCI SCSI single-ended or differential option board. It presumes general knowledge of SCSI, knowledge of the host system in which the PCI SCSI option board is installed, and knowledge of the SCSI devices to which the PCI SCSI board port is to be cabled.
This guide consists of the following chapters:
Chapter 1, “Features of the PCI SCSI Option Board,” describes the SCSI connector on the PCI SCSI option boards, compatible media, and cabling. It also explains SCSI basics.
Chapter 2, “PCI SCSI Board Connector Pinouts,” gives pinouts for the single-ended or differential connector on the two versions of the board.
In addition to this manual, have handy the owner's guide for the server or workstation in which the PCI SCSI board is installed, and the owner's guide for the peripheral device(s) with which the PCI SCSI board interfaces.
