The HMV U320-RX communicates with your computer using the industry standard SCSI Ultra320
interface. You must have a compatible SCSI Host Adapter installed in your computer to work with the
HMV U320-RX storage system. Some computers have a built-in native SCSI port, check your computer
for availability.
To maximize the HMV U320-RX’s Ultra320 interface, the SCSI Host Adapter in your computer should
also be rated for Ultra320. However, the slower Ultra160, Ultra2 and Ultra Wide SCSI rated host adapters
will work but at a lower transfer rate.
Check to make sure the Host Adapter is physically installed correctly and the appropriate Host Adapter
drivers are loaded and functioning properly before connecting the HMV U320-RX to your computer
system.
800009 rev C2 Page 11 of 32
Rear View
POWER IN
The U320-RX is equipped with an auto ranging power supply. When an AC power source is provided, the
unit will be in a power standby mode.
POWER SWITCH
This is not the main power switch. In the ON (1) position, the U320-RX provides power to the entire
U320-RX. In the OFF (0) position, the U320-RX switches to power standby mode and remove power to
the disk drives and controllers, but some standby power remains. The OFF(0) position does not remove the
main power to the U320-RX. Removing the power source from Power In will completely remove power.
REMOVABLE POWER SUPPLIES
The removable power supplies must be serviced by trained personnel only, call our technical support
department for additional instructions.
SCSI ID
Each SCSI device attached to a SCSI channel must have it’s own unique ID setting. Valid ID for Wide
SCSI are from 0 to 15. Most SCSI host adapters inside your computer typically occupies ID 7. If there are
other SCSI devices on the SCSI channel, ensure that there are no SCSI ID conflicts. If you are unsure
which ID to use and the U320-RX is the only device attached to this particular channel of the host adapter,
ID 0 can be used.
To change the value, use a pointy instrument (pointy pen) and press the buttons just
above and just below the number to change it.
The U320-RX must be turned off and back on again to make a new SCSI ID setting take effect.
Page 12 of 32 HMV U320-RX User’s Guide
MODE Selection (RAID Level)
(see table on right)
Mode Selection is a unique feature of Huge Systems and it is a convenient way to select the desired
operating mode of the U320-RX. No need of complicated software and serial port configuration
procedures.
To change the value, use a pointy instrument (pointy pen) and press the buttons
just above and just below the number to change it.
IMPORTANT: Changing the Mode can cause any existing data to be over written.
Make sure any data you want to keep is stored elsewhere before making any changes.
Remove or delete any known partitions before changing the mode, this will keep the OS from getting
confuse due to left over file systems information left on the U320-RX.
Consult the RAID Compatibility table in the Application Notes section to ensure proper operation.
Double Beep
As a precautionary measure to protect from un-intentional mode changes. A combination of holding down
the Mode Set Button and turning the unit on must be performed to cause the change.
1) Turn off the computer.
2) Determine the Mode desired and note the Mode Selection value.
3) Set the value on the Mode Selection switch. Use a pointed instrument and press the tiny button
above or below the number window.
4) Turn the power off to the U320-RX unit.
5) Press and hold the Mode Set Button.
6) Apply power to the U320-RX.
7) Within about 20 seconds you will hear two beeps to confirm the change.
8) Release the Mode Set Button.
9) Turn the computer on.

completely wipe out any previous configuration and settings.
Manufacturing
Test 7
This mode will overwrite data on the HMV U320 as the
diagnostic will perform read and write tests on every drive and
on every block of data. The unit records vital parameters of
each disk drive’s performance, and it can be retrieved using the
Diagnostic Port for further analysis.
*Make sure to “Double Beep” to set the mode.
** No need to use the HD Turbo mode in a striped two channel configuration. For a single channel
configuration, the HD Turbo mode ensures the highest data rates are used of the disk drives to provide
sufficient performance required for HD video resolution operation, the trade off is a reduction in storage
capacity. If full capacity AND HD performance is required, the solution is to stripe two channels of the
HMV-U320 using the Operating System stripping utility.

MODE SET Button
This switch has a dual role function. During power up, it acts as a Mode Set switch and during normal
operation it is used as the Start Rebuild switch.
During the 1st 20 seconds of power up, this switch acts as a Mode Set switch and is used in conjunction
with the Mode Selection option. See the Mode Selection section for additional information.
During normal operation and only when the U320-RX is in the RAID 3 modes, this switch is used as an
alarm mute and drive rebuild start button. When a defect drive has been replaced, this rebuild process
brings the U320-RX back up to it’s fully protected mode. See Audible Alarm and Drive Replacement
sections for additional information.
SCSI IN / OUT
The HMV U320-RX Dual Max contains two RAID controllers (Side A and Side B), each controller have a
pair of SCSI 68-pin high density connectors. They function as an IN and an OUT connection with internal
loop-through for the SCSI channel. This SCSI channel is compatible with Ultra320, Ultra160, Ultra2, and
other SCSI standards. HVD (High Voltage Differential) is not supported.

Daisy chaining
If you have multiple SCSI devices to connect up, you can connect (daisy chain) other SCSI devices as
shown. At the back of the HMV U320-RX you will have at the SCSI IN connectors SCSI cables connected
to your host computer, and at the SCSI OUT connectors SCSI cables connected to your other SCSI devices.
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 Ultra160, Ultra2, Ultra Wide, narrow SCSI, etc…
will 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. For HMV U320-RX Max, only Side A applies.
Do not exceed maximum of four devices in a chain to ensure SCSI data transfer reliability.

If this indicator is lit, the U320-RX requires help. Normally this is associated with an audible alarm and
one of the drive indicator will be flashing slowly. A drive replacement might be necessary. See Audible
Alarm section.

Audible Alarm
The HMV U320-RX will sound an alarm if there is a problem with the RAID operation. Corrective actions
can be applied to rectify the problem.
6 Rapid Beeps During Boot Time
6 rapid beeps during boot time is normally associated with SCSI cabling, SCSI termination, or power up
sequence related. Always turn on the MediaVault on first, then turn on the computer. You might need to
physically remove and re-insert the SCSI connectors along the SCSI path, this includes the connectors at
the SCSI controller, at the MediaVault and the terminators.
Check to ensure there are no other SCSI devices on the bus using the same SCSI ID address.
Try removing any other SCSI devices that shares the same SCSI bus as the Media Vault, leaving just the
Media Vault as the only SCSI device will help to identify if there is a conflict with other devices.
6 Rapid Beeps During Normal Operation
6 rapid beeps during normal operation indicates either there is a SCSI interface issue or a disk drive in the
MediaVault has timed out. Check to ensure all SCSI connections are securely in place, you might need to
physically remove and re-insert the SCSI connectors along the SCSI path, this includes the connectors at
the SCSI controller, at the MediaVault and the terminators.
Slow Beeps
One or more slower beeps indicate a bad drive or an intermittent drive, the number of beeps indicates
which drive is having problems. When operating in RAID 3 mode the HMV U320-RX is still available for
normal operation without performance degradation, but the beeps indicate that a drive is down and you are
running in a degraded RAID 3 state. Should another drive fail your are in danger of loosing data.
To service the unit, any data needs to be kept must be off loaded to another fully functional unit. Sent the
entire defective unit to the service center, the defective component will be replaced or repaired and then
returned back to the sender. Data will not be preserved by the service center. Upon receiving the repaired
unit, reformat and partition the U320-RX and restore any needed data.
Constant Solid Beep
This would indicate a drive is down. The SERVICE indicator should also be on. One of the drive indicator
should exhibit a slow blink (one second on then one second off). This drive needs to be serviced. See
Drive Replacement section for more instructions.
You may mute the alarm by pressing the Mode Set button once. Pressing the Mode Set button a second
time will start the rebuilt process, you typically only would do this after a replacement drive module had
been installed to replace a defective drive module.
Power Supply Replacement
The removable power supplies must be serviced by trained personnel only, call our technical support
department for additional instructions.

Drive Replacement
Access to the disk drive modules are from the front of the U320-RX unit. The Front Panel needs to be
removed to access the modules. While modules may be removed and inserted when the U320-RX is ‘hot’
(powered on), but we recommend turning off the U320-RX when servicing the disk modules. Make sure
to shutdown the computer properly first before turning off the U320-RX.
Remove the front panel
The front panel snaps on to four snap pins, to remove the front panel:
Tower configuration - Lift the front of the U320-RX by a couple of inches using the front handle, locate the
cut out of the lower panel with your other hand and pull the lower part of the panel forward until it un-
snaps, then continue the forward pull and lift up, the top panel snaps will un-snap as the forward and up
movement is continued.
Rack mount configuration – Locate the cut out next to the right hand side handle, pull the front panel
forward until it un-snaps, then continue to forward pull till the left side of the panel un-snaps.
Removing disk drive module
Identify and make a note of the module to replace by locating the slow blinking light next to it.
Shutdown the computer and turn off the U320-RX.
Completely loosen the captive thumb screws to the disk drive module.
Grab the handle of the disk drive module and GENTLY pull it towards you. Set the defective module a
side.
Insert the replacement disk drive module GENTLY by aligning the rails to the slots in the U320-RX,
slowly and gently insert the module all the way into the U320-RX until it engages the internal connections
and snaps into place.
Secure the left and right hand thumb screws.
Install the front panel.
Turn the U320-RX back on. Wait 30 seconds before rebuild.
Rebuilding a down drive (RAID 3 mode only)
The expected slow beeps followed by a continuous beep would indicate that a drive is still down. Press the
Mode Set switch one time to mute the alarm, pressing the Mode Set switch a second time will start the
rebuild process. During rebuild, the audible alarm will be silent but the Service indicator will be lit during
rebuild, it will go off when rebuild is complete.
Rebuild time will vary depending on your system work load, when system is idle the rebuild time is
approximately 12Gbytes/min or 83 minutes to rebuild a 1TByte unit.

Formatting and Partitioning
Formatting and Partitioning of the Media Vault is required to prepare the unit for usage. After the unit is
physically connected to your computer, use the following sections as a guide to locate and execute the
appropriate utility to format and partition the Media Vault.
The HMV U320-RX is seen as two large SCSI disk drives by the SCSI host adapter in your computer.
Install the appropriate driver for your SCSI Host Adapter. No additional software or drivers are necessary
to use the HMV U320-RX. Treat the HMV U320-RX as a pair of normal ordinary hard disk drives when
partitioning and formatting.
Macintosh G4 / G5 in OS X
Use the following configuration to get maximum speed from the U320-RX with OS 10.3.x for video
capturing/playback and editing.
Check and ensure you are using the latest recommended configuration for your capture card and editing
software, update any software or drivers as necessary.
