Mounting the Drive in a 5.25-Inch Drive Bay
If you are mounting the drive in a 5.25-inch drive bay, you must use a drive with
mounting brackets attached. As shown in Figure 10, the 5.25-inch drive brackets
have four screw holes on the bottom and six on each side.

Connecting the SCSI Interface Cable
DAT 72 and DDS-4 drives can be used with two different types of SCSI interfaces:
Ultra2 SCSI (LVD) or “Wide” (16-bit) single-ended SCSI bus. The drive can
automatically detect whether it is connected to an LVD or single-ended wide SCSI
bus.
Note:
The DAT 72 and DDS-4 drives do not work in a SCSI-1 environment.
Connecting to a 68-pin Wide SCSI or LVD Bus
To connect the drive to an LVD or wide SCSI bus, first turn off all power to the drive
and computer. Then attach the interface cable to the SCSI interface connector on the
back of the drive (see Figure 11).
