Understanding Scsi; Scsi Ids - Adaptec APA-1460 User Manual

Understanding SCSI

SCSI (pronounced "scuzzy") stands for Small Computer Systems
Interface. SCSI is an industry standard computer interface for con-
necting SCSI devices (such as hard disk drives, CD-ROM drives, and
scanners) to a common SCSI bus.
A SCSI bus is an electrical pathway consisting of a SCSI adapter
(such as the SlimSCSI adapter) installed in a computer and one or
more SCSI devices. SCSI cables are used to connect the devices to the
SCSI card.
For the SCSI bus to function properly, SCSI IDs must be assigned to
the SCSI devices and the SCSI adapter, and the SCSI bus must be
properly terminated.

SCSI IDs

Each device attached to the SlimSCSI 1460 adapter, as well as the
adapter itself, must be assigned a unique SCSI ID number from 0 to
6. A SCSI ID uniquely identifies each SCSI device on the SCSI bus
and determines priority when two or more devices are trying to use
the SCSI bus at the same time.
The SlimSCSI 1460 adapter is preset to SCSI ID 7, which gives
it the highest priority on the SCSI bus.
In Windows 95, you can use the Device Manager to view the
SCSI ID and other information about each installed SCSI
device.
If you installed Adaptec EZ-SCSI software, you can use the
SCSI Explorer utility to view the SCSI ID and other informa-
tion about each installed SCSI device.
