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 1460 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 1460. 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 1460. For purchasing information, contact
