4. If the autoloader is the last device on the SCSI bus, install a terminator on
the unused SCSI connector.
Daisy-chaining—If the autoloader is not the last device on the bus,
connect another SCSI cable from the autoloader’s SCSI connector to the
next device on the bus.
Bus termination—If there are additional devices on the SCSI bus, ensure
that only the device at the physical end of the bus is terminated.

Both LTO-2 and LTO-3 SCSI tape drives require an Ultra 3 or
LVD 160 terminator to function properly on the SCSI bus. An
inadequate terminator will result in various SCSI bus issues,
including bus hangs and Read/Write failures.
See Tape Drive Operation (Tape drive fails with sporadic
errors) on page 107 for failure symptoms associated with using
the wrong terminator.
