ogy, or if you would like a quick review of SCSI technology,
read this section. If you know what SCSI is all about, skip to
the next section, Connecting SCSI Devices on page 12.
You can connect as many as 15 SCSI devices—such as hard disk
drives, scanners, and CD-ROM drives—to each Adaptec Power-
Domain 29160/29160N installed in your Power Macintosh.
However, before connecting the devices, you may need to do the
following:
•
Change SCSI IDs if two or more devices share the same
SCSI ID
•
Enable or disable termination
Following are some guidelines for setting SCSI IDs and termina-
tion on SCSI devices. Because setup can vary from device to
device, always refer to the device documentation for specific
instructions.
Understanding SCSI
SCSI (pronounced "scuzzy") is an acronym for Small Computer
System Interface. SCSI is an industry standard computer inter-
face for connecting 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 card, such
as the Adaptec PowerDomain 29160 and 29160N, installed in a
computer and one or more SCSI devices connected to the card by
SCSI cables.
For the SCSI bus to function properly, SCSI IDs must be assigned
to the SCSI devices and the SCSI PCI card, and the SCSI bus
must be properly terminated.
