Connecting the Cables and Terminating the SCSI Bus 
9
You can connect the DLT-S4 tape drive to the host computer as a single 
device, or as one of two total devices connected via a SCSI cable with 
multiple SCSI connectors in a “chain” configuration.
 
If you are connecting two devices to the SCSI bus, connect only one tape 
drive to the host computer at this time. Finish the installation procedure 
and confirm that the host computer and tape drive are communicating 
) before adding the
 
additional 
device (see 
).
Follow these steps to connect the tape drive to the host computer (see 
1
Ensure that the tape drive, host computer, and all peripheral devices 
(such as printers) are turned off.
2
Disconnect any other SCSI devices from the SCSI bus at this time. 
You can add them back on later (see 
).
3
Ensure that the SCSI cable(s) and terminator(s) are Ultra320 and SPI-4 
(or SPI-5) compatible. 
4
Terminate the SCSI bus by making sure a terminator is installed in 
the very last connector of the SCSI cable. 
Note:
Use care when connecting the cables to avoid bending or 
damaging the connector pins.
Caution:
Never connect the tape drive while the tape drive, 
host system, or peripheral devices are turned on. 
Doing so could result in damage to the tape drive or 
other peripheral devices.
Note:
SPI refers to SCSI Parallel Interface; you can learn more 
from this standard at the Web site
