SCSI Termination
The SCSI bus is an electrical transmission line and it must
be terminated properly to minimize reflections and losses.
You complete the SCSI bus by setting termination at both
ends.
You can let ADAC Ultra2 S466 automatically provide
SCSI termination at one end of the SCSI bus. You can
terminate the other end of the SCSI bus by attaching an
external SCSI terminator module to the end of the cable or
by attaching a SCSI device that internally terminates the
SCSI bus at the end of the SCSI channel.
Selecting a Terminator Use standard external SCSI terminators on a SCSI
channel operating at 10 MB/s or higher synchronous data
transfer.
Terminating Internal SCSI Disk Arrays Set the termination so that SCSI
termination and termination power are intact when any disk
drive is removed from a SCSI channel, as shown below:
