Preparing to Install the Tape Drive
DLT-V4 Product Manual

interface (SCSI) bus, but you can also attach it to a single-ended (SE) SCSI
bus.
Make sure the SCSI host adapter or controller supports these
configurations. If you connect the tape drive to an SE bus, or if there are
SE devices attached to the same SCSI bus, the tape drive’s performance is
limited to the maximum data transfer speed and maximum cable lengths
of the SE bus (usually 40 MB/s).
The DLT-V4 is not compatible with a high-
voltage differential (HVD) SCSI bus
.
Physical Considerations
2
If you attach the tape drive to a narrow (50-pin) SCSI bus, you must use a
customer-supplied 68-pin to 50-pin adapter that terminates the unused 18
pins. These adapters are sometimes labeled
high-byte termination
.
Make sure the total length of the SCSI bus does not exceed the ANSI SCSI
standard of 19 feet (6 meters) for an SE SCSI bus, 40 feet (12 meters) for an
LVD SCSI bus with multiple devices, or 82 feet (25 meters) for an LVD
SCSI bus with a single device.
SATA Requirements
2
The DLT-V4 SATA interface tape drive (internal only) incorporates a
Serial ATA (SATA) bus.
Make sure the total length of the internal SATA data cable does not
exceed the SATA standard of approximately 40 inches (1 meter).
