Daisy chaining

If you have multiple SCSI devices to connect, they can be daisy chained together as shown. At the back of
the U320-R you will have at the SCSI IN connector a SCSI cable connected to your host computer, and at
the SCSI OUT connector a SCSI cable connected to your other SCSI device.

Keep in mind that all connected SCSI devices must be rated at and configured to run at Ultra320 for
maximum data transfer, mixing slower devices such as Ultra2, Ultra Wide, narrow SCSI, etc… could
reduce the data transfer rate to the slowest device on the SCSI channel.

Please ensure that 1) the total SCSI cable length are kept as short as possible (Maximum 12 meters); 2)
remember to use a terminator at the end device of each SCSI chain; 3) No duplicated or SCSI ID conflict
on any particular SCSI channel.

Do not exceed maximum of four devices in a chain to ensure SCSI data transfer reliability.
