Although the Adaptec SCSI Card 39160 is a 64-bit PCI card, it also
works in a 32-bit PCI slot. When installed in a 32-bit PCI slot, the
card automatically runs in the slower 32-bit mode.
This User’s Reference provides information about troubleshooting,
SCSI termination, and other important topics. It also explains how to
use the built-in SCSISelect utility if you need to change the Adaptec
SCSI Card 39160 settings.
Note:
Read the Adaptec SCSI Card 39160 Installation Guide if
you need instructions on installing the SCSI Card and con-
necting SCSI devices to it.
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 a hard disk drive, CD-ROM drive, or
scanner) to a common SCSI bus.
A SCSI bus is an electrical pathway that consists of a SCSI adapter
card (such as the Adaptec SCSI Card 39160) installed in a computer
and one or more SCSI devices. SCSI cables are used to connect the
devices to the SCSI adapter card. The Adaptec SCSI Card 39160 has
two independent SCSI buses (channels).
For the SCSI bus to function properly, a unique SCSI ID must be
assigned to the SCSI card and each SCSI device connected to it, and
the SCSI bus must be properly terminated.
