Inspection
Examine the MV U320-R or MV U320-RX for:
• Correct part number on the barcode sticker at the rear of the unit (i.e., that the MVxxxxxxxxxx and SNxxxxxxxxx numbers on the
barcode stickers match the information on the MV U320-R or MV U320-RX invoice).
• A front panel that is marked for U320 and U160 SCSI connections.
• Scratches, gouges, dents, or cracks in the enclosure.
• Cracked or loose handles and/or feet.
• Missing switches.
• Bent, scratched, or missing pins on the connectors.
• Rust, discoloration, or signs of corrosion or water, moisture, or chemical damage.
• Loose or missing screws.
• Ripped, illegible, or missing safety labels or stenciled lettering.
• Parts that rattle or slide around the inside of the unit, when the unit is lifted.
Installation
Hardware Installation and Configuration
The MV U320-R is available only in a mini-tower configuration; the MV U320-R cannot be rack-mounted. The MV U320-RX is
shipped with 19-inch rack-mounting hardware installed. Additional hardware is provided to convert the MV U320-RX to a tower
configuration.
Rack Mounting: MV U320-RX Only
The MV U320-RX rack mount requires 4U (7 inches) of rack space for mounting. Place the MV U320-RX in the rack. Secure the unit
with the appropriate screws (not included), using the four mounting points. See Below.
Tower Configuration: MV U320-RX
Remove the three screws from the left and right rack mount ears. See Below.

•The MV U320-R or MV U320-RX communicates with your computer using an industry-standard SCSI interface. You must
have a compatible SCSI Host Adapter installed in your computer to work with the MV U320-R or MV U320-RX storage
system. Some computers have a built-in native SCSI port. Check your computer for availability.
•To maximize the Ultra320 interface of the MV U320-R or MV U320-RX, the SCSI host adapter in your computer should be
rated for Ultra320. Ultra160, Ultra2, and Ultra Wide SCSI rated host adapters will work but at a slower transfer rate.
•Make sure the host adaptor is installed correctly, and that the appropriate host adapter drivers are installed and functioning
properly, before connecting the MV U320-R or MV U320-RX to the host computer.
SCSC In/Out Connections
MV U320-R
The MV U320-R has a pair of SCSI 68-pin high density (68HD) connectors. This SCSI channel is compatible with Ultra320,
Ultra160, Ultra2, and other SCSI standards. HVD (High Voltage Differential) is not supported.
Host Connections
Use Ultra320-rated SCSI cables to connect each side of the SCSI channel to your host computer.
•Connect the Side A SCSI IN to the first SCSI channel of the host computer.
Terminator
Use an Ultra320-rated SCSI terminator to terminate the SCSI connection. Connect the terminator to SCSI OUT.

MV U320-RX
The U320-RX contains two RAID controllers (Side A and Side B). Each controller has a pair of SCSI high-density 68-pin connectors.
Each SCSI channel is compatible with Ultra320, Ultra160, Ultra2, and other SCSI standards. HVD (High Voltage Differential) is not
supported.
See the figure below for the SCSI configuration per Side A and Side B of the MV U320-RX.
Side A and Side B SCSI Connectors.
Host Connections
Use Ultra320-rated SCSI cables to connect each side of the SCSI channel to your host computer.
• Connect the Side A SCSI IN to the first SCSI channel of the host computer.
• Connect the Side B SCSI IN to the second SCSI channel of the host computer.
Terminator
Use two Ultra320-rated SCSI terminators to terminate the SCSI connections. Connect the terminators to the SCSI OUT on Side A
and Side B.

Daisy Chaining
MV U320-R
Multiple SCSI devices can be connected by a daisy chain, as indicated in the figure below.
Make the following connections:
• Run a SCSI cable from the SCSI IN connector of the MV U320-R to the SCSI connector of the host computer.
• Run a SCSI cable from the SCSI OUT connector of the MV U320-R to the SCSI IN connector of another unit (such as another MV
U320-R). The other unit must have a terminator inserted in the unused SCSI connector.
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.
Make sure of the following:
• That the total SCSI cable length is as short as possible (a maximum of two meters).
• To use a terminator at the end device of each SCSI chain.
• That there are no duplicated connections or SCSI ID conflict on any SCSI channel.
Do not exceed a maximum of four devices in a chain, to ensure the reliability of the SCSI data transfer.

MV U320-RX
Multiple SCSI devices can be connected by a daisy chain, as indicated in the figure below.
Make the following connections:
• Run SCSI cables from the SCSI IN connectors of the MV U320-RX to the SCSI connectors of the host computer.
• Run SCSI cables from the SCSI OUT connectors of the MV U320-RX to the SCSI IN connectors of another unit (such as another
MV U320-RX). The other unit must have a terminator inserted in the unused SCSI connector.
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.
Make sure of the following:
• That the total SCSI cable length is as short as possible (a maximum of 12 meters).
• To use a terminator at the end device of each SCSI chain.
• That there are no duplicated connections or SCSI ID conflict on any SCSI channel. For the MV U320-RX Max, use only Side A.
Do not exceed a maximum of four devices in a chain, to ensure the reliability of the SCSI data transfer.
DIAG - Diagnostic Port
A serial diagnostic cable is supplied with the unit and allows unit diagnostics, as well as firmware updates.
Editing System Requirements
For video editing, the following video editing equipment, operating system, and video cards must be installed on your computer, or
connected to the computer or to the MV U320-R or MV U320-RX.
• Ultra320 or compatible SCSI host adapters [for the MV U320-R], or an Ultra320 or compatible single or dual channel SCSI host
adapter [for the MV U320-RX].
• Windows 2000, Windows Server 2003, Windows XP, Mac OS, IRIX, Linux.
• Video Editing software.
• A video input source.
