Connecting Parallel SCSI Cables
There are two recommended ways to cable SCSI tape drives: two tape drives per SCSI bus or one tape
drive per SCSI bus.
To connect two tape drives per SCSI bus:
1Connect one end of the SCSI cable to the top SCSI port of the bottom tape drive. Then connect the
other end of the cable to the bottom SCSI port of the tape drive above. To avoid possible performance
issues, do not connect more than two tape drives per SCSI bus.
2Use another SCSI cable to connect the bottom tape drive of the SCSI bus to your host system.
3Use a SCSI terminator to terminate the top tape drive of the SCSI bus.
To connect one tape drive per SCSI bus:
4Use a SCSI cable to connect the bottom port of the tape drive to your host system.
5Attach a SCSI terminator to terminate the top port of the tape drive.
CAUTION The library supports a maximum cable length of 12 meters (including
internal wiring) for Ultra160 SCSI and Ultra 320 SCSI cables.
