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:
