Note: LW and LC drives do not have internal terminators or
any other way of adding internal terminators to the
drive; use external active termination if required.
Use active (ANSI SCSI-2 Alternative 2) terminators
when terminating the bus. Use active negation
terminators when terminating a SCSI Ultra2 bus
operating in Low Voltage Differential (LVD) mode.
