More Information About Termination The last SCSI device on the end of each SCSI bus cable must be terminated, and termination must be disabled for all other devices in the middle of the cables. Ultra320/160 and Ultra2 SCSI devices are automatically unterminated, but Ultra SCSI and Fast/Wide SCSI devices do have termination that you must check. For more information, refer to the documentation for each SCSI device. If you are using external Ultra2 or Ultra320/160 devices, be sure to use an LVD terminator to terminate the last device in the chain. If you use a single-ended, active terminator (sometimes called an Ultra terminator) the SCSI devices will not operate properly. Troubleshooting If you have any problems while installing the Adaptec SCSI Card 29320A, check the following items first: ■ Are all SCSI devices powered on? ■ Are all SCSI cables and power cables properly connected? ■ Does each device on each SCSI bus have a unique SCSI ID? ■ Does the total SCSI cable length exceed the maximum allowable length? ■ Is the SCSI bus properly terminated? If you are still unable to resolve a problem, contact the system manufacturer for help. Adaptec SCSI Card Driver Software Note: To use the Adaptec SCSI Card 29320A, driver software must be installed for your operating system. Installation of the driver software varies depending on how and where you purchased the Adaptec SCSI Card 29320A. 10

More Information About Termination
The last SCSI device on the end of each SCSI bus cable must be
terminated, and termination must be
disabled
for all other devices
in the middle of the cables. Ultra320/160 and Ultra2 SCSI devices
are automatically unterminated, but Ultra SCSI and Fast/Wide
SCSI devices do have termination that you must check. For more
information, refer to the documentation for each SCSI device.
If you are using external Ultra2 or Ultra320/160 devices, be sure to
use an LVD terminator to terminate the last device in the chain. If
you use a single-ended, active terminator (sometimes called an
Ultra terminator) the SCSI devices will not operate properly.
Troubleshooting
If you have any problems while installing the Adaptec SCSI Card
29320A, check the following items first:
■
Are all SCSI devices powered on?
■
Are all SCSI cables and power cables properly connected?
■
Does each device on each SCSI bus have a unique SCSI ID?
■
Does the total SCSI cable length exceed the maximum allowable
length?
■
Is the SCSI bus properly terminated?
If you are still unable to resolve a problem, contact the system
manufacturer for help.
