Solution
The SCSI terminator
might be loose or
missing.
1. Make sure an active Low-Voltage
Differential/Single-Ended (LVD/SE)
terminator is properly seated on the
open SCSI connector on the rear panel
of the external drive or on the last
device on the SCSI bus.
2. Make sure an active LVD/SE terminator
is in place on the SCSI ribbon cable for
the internal drive.
The SCSI bus might
be improperly
terminated.
1. If your DLT VS160 Drive is the last or
only device on the SCSI bus, make sure
the drive is properly terminated.
2. If your DLT VS160 Drive is not the last
or only device on the SCSI bus, check
all SCSI cable connections and make
sure the last device on the SCSI bus is
terminated.
3. Make sure termination is set properly on
the SCSI host adapter.
4. If you attach the 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."
5. Regardless of which device is used to
terminate the SCSI bus, it must have
power applied and be turned on for
proper termination to occur.
The SCSI terminator
might not be at the
end of the SCSI bus or
more than two
terminators might be
present on the SCSI
bus.
Make sure the terminators are placed only
at each end of the SCSI bus — normally
one at the host adapter and one on the last
device on the bus. However, if both internal
and external devices are attached to the
same SCSI host adapter, the adapter may
be positioned in the middle of the SCSI bus
and should not be terminated. In that case,
the SCSI devices on each end of the bus
must be terminated.
The SCSI host
adapter might be in a
defective expansion
slot.
Move the SCSI host adapter to a different
expansion slot.
