Connecting the SCSI Interface Cable

SCSI Termination

Connecting the Power Cord

The external drive provides two 68-pin, shielded connectors on the rear panel of the
enclosure. Either connector can be used as a SCSI IN or SCSI OUT connection (you
can use either connector to attach the drive to the host computer or to another SCSI
device).
Turn off your computer and all SCSI devices. Then attach a SCSI cable from the
host adapter or from another (unterminated) SCSI device to the external drive.
Note: The DAT 72 and DDS-4 drives do not work in a SCSI-1 environment.
If the DAT 72 or DDS-4 drive is the last device or the only device in a SCSI chain,
you must install a terminating plug on the unused SCSI connector. See Figure 15 for
two SCSI termination examples.
