Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the otherconnector. Keyed connectors ensure that the pin-1 wire in the cable (indicated by the colored stripe along one edge of the cable) goes to the pin-1 end of theconnector. The pin-1 end of a connector on a board or a card is usually indicated by a silk-screened "1" printed directly on the board or card.SCSI Device Installation GuidelinesThis section describes how to configure and install SCSI devices in your computer.SCSI ID NumbersInternal SCSI devices must have a unique SCSI ID number from 0 to 15.
