Terminating The Scsi Bus; Obtaining Scsi Cables - Adaptec APA-1480 User Manual

Terminating the SCSI Bus

To ensure reliable communication on the SCSI bus, terminators must
be installed (or enabled) on the devices at the physical ends of the
SCSI bus. The terminators on all devices between the physical ends
must be removed (or disabled). Termination on the SlimSCSI 1480 is
permanently enabled, since it is always at one end of the SCSI bus.
There are various methods for terminating disk drives and other
SCSI devices. Read the device documentation if you are not sure
how to do this. Here are some general guidelines for termination:
Termination is usually controlled by installing or removing a
SCSI terminator. On some SCSI devices, termination is con-
trolled by setting a switch on the back of the device, as shown
in the illustration on page 4.
Most SCSI devices come from the factory with termination
enabled.

Obtaining SCSI Cables

You will need additional SCSI cables if you connect more than one
SCSI device to your SlimSCSI 1480. It is important to use high-
quality cables to ensure that data is read and written correctly.
Adaptec provides high-quality SCSI cables designed specifically for
use with the SlimSCSI 1480. For purchasing information, contact
Adaptec at 1-800-442-7274, Monday to Friday, from 6 a.m. to 5 p.m.
