Installing an External Tape Drive
Preparing the Tape Drive
Note

3 Examine the SCSI devices already in place.


Is there another external device on the SCSI bus?
If yes, attach the tape drive in the middle of the SCSI chain, allowing
the other external device to provide termination. Plug the tape drive into
the computer's SCSI connector and plug the other device into the tape
drive's second SCSI connector. The device that comes last in the chain
must be actively terminated.
Remember that if you have devices attached to your SCSI host adapter
both inside your computer and external to your computer, the SCSI host
adapter must NOT be terminated (since it is, therefore, in the middle of the
SCSI chain). Consult your SCSI host adapter documentation for
instructions on how to change the board's termination.
