connecting external scsi devices

9Connect power cables to all external device(s) and to thecomputer.The last SCSI device on the end of each SCSI bus cable must beterminated, and termination must be disabled for all other devicesin the middle of the cables. Ultra320/160 and Ultra2 SCSI devicesare automatically unterminated, but Ultra SCSI and Fast/WideSCSI devices do have termination that you must check. For moreinformation, refer to the documentation for each SCSI device.If you are using external Ultra2 or Ultra320/160 devices, be sureto use an LVD terminator to terminate the last device in the chain.If you use a single-ended, active terminator (sometimes called anUltra terminator) the SCSI devices will not operate properly.If you have any problems while installing the Adaptec SCSI Card39320D, 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 maximumallowable length?•Is the SCSI bus properly terminated?If you are still unable to resolve a problem, contact the systemmanufacturer for help.STEP 4MORE I NFORMATION ABOUT TERMINATIONTROUBLESHOOTING
