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 MegaRAID Express 500 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:
