A-1AIn this AppendixUnderstanding SCSISCSI (pronounced “scuzzy”) stands for Small Computer SystemInterface. SCSI is an industry standard computer interface forconnecting SCSI devices (such as a hard disk drive, CD-ROMdrive, or scanner) to a common SCSI bus.A SCSI bus is an electrical pathway that consists of a SCSI card (suchas the SCSI Card 2930CU) installed in a computer and one or moreSCSI devices. SCSI cables are used to connect the devices to the SCSIcard.For the SCSI bus to function properly, each SCSI device must have aunique SCSI ID and must be correctly terminated. For more information,see the next section (SCSI IDs) and Terminating the SCSI Bus onpage A-3.SCSI IDs A-2Terminating the SCSI Bus A-3Preparing SCSI Devices for Installation A-4Using SCSI Devices A-4Installing Multiple SCSI Cards A-5
