■ General

The extension unit WJ-HDE300 can contain up to four hard disk drives per unit to add available disk space to the digital disk recorder WJ-HD316/WJ-HD309. Up to seven extension units can be connected to a digital disk recorder. The units can be operated in RAID level 5* mode for high tolerance to disk error.

* RAID level 5 (Redundant Arrays for Independent Disks, independent data disks with distributed parity blocks)

RAID level 5 regards 3 or more drives as one drive, and it is possible to read data by automatically attaching error correction data even though one of the drives is broken. (It is impossible to read data if 2 or more drives are broken.) RAID level 5 requires a minimum of 3 drives to implement. When using the RAID function, logical disk size of the extension unit will be as below. Logical disk size = Smallest size of the disk among the disks in the extension unit x (Number of the disks in the extension unit - 1) The actual space may be several percent lower than the logical space.

* Important

When set to RAID level 5, the digital disk recorder will not access the HDD preinstalled in it, but will access only the HDDs in the extension unit.

■ Precautions

• Do not operate the appliance beyond its specified temperature, humidity or power source ratings. Do not use the appliance in an extreme environment where high temperature or high humidity exists. Use the appliance at temperatures within +5 °C to +45 °C (41 °F to 113 °F) and humidity below 85 %. The input power source for this appliance is 120 V AC 60 Hz.

• Avoid shock and vibration Shock or vibration may damage the HDD. The HDDs are fragile especially when the HDD motors are revolving and the HDD POWER indicator lights. Be sure to turn off either switch: the POWER switch on the rear panel, or the HDD POWER switch inside the front lid: before you mount the unit into a rack or dismount it. Do not move the HDD for 30 seconds after turning off the power.

• Pay attention to static electricity Put your hand on a metallic surface to discharge static electricity before installation. Do not touch components mounted on the HDD directly with your hand. Hold only the two sides of the HDD when installing.

• Avoid condensation on the surface of the HDD. If this happened, do not turn on the power of the appliance and leave the appliance for around 2 hours.

Wait until the dew evaporates in any of the following cases.

• The appliance is moved to a place significantly different in temperature or humidity.

• The appliance is moved out from an air-conditioned room.

• The appliance is placed in an extremely humid place.

• The appliance is placed in a room where a heater has just been turned on.

• Consumable parts Contact your dealer about replacement when the time comes. A hard disk drive needs replacing after a certain length (depends on the model) of operation. Cooling fans also need replacing after around 20 000 - 30 000 hours of operation.

• Do not block the ventilation opening or slots on the cover. To prevent the appliance from overheating, place it at least 5 cm (2 inches) away from the wall.

• Avoid placing the unit on an inclined surface. Otherwise, malfunction or damage to the disk may occur. Place the unit horizontally.

Important

• Changing the MODE switch will not be accepted when the ERROR indicator lights red and/or when HDD 1-4 indicate a system error status by lighting red and orange. When this happens, ask your dealer to solve the error.

• When set to RAID5, the HDD preinstalled in the digital disk recorder will not work. Instead, it is applied only to the HDDs installed in the extension unit and the digital disk recorder will perform storage and readout of the image data by accessing the extension unit.

• The position of the MODE switch of all units in a system must be the same.

• The available disk space of the unit can be logically calculated as follows. The actual space may be several percent lower than you calculated depending on the HDD type used and their combination. The most efficient way is to use the same type drives.

When SINGLE is selected, it will be the sum of all the HDD sizes. When RAID 5 is selected, it will be as follows. When 3 HDDs are in the unit: It will be double the size of the smallest HDD size. When 4 HDDs are in the unit: It will be triple the size of the smallest HDD size.

For example, if 4 HDDs of 80 GB, 120 GB, and two 160 GB are mounted, the available disk space will be 80 G x 3 = 240 GB.

!3 Reset button [RESET]

This button is located inside the unit. To access this button, it is necessary to detach the front cover. Press this button using a small screw driver (not supplied).

• When SINGLE is selected After adding or replacing any of the HDDs, press this button only. Refer to page 11 and 12 for details.

• When RAID 5 is selected This button is used in combination with the RECOVER button and MODE switch after adding or replacing any of the HDDs. Refer to page 11 and 12 for details.

Important

Do not press the RESET button and the RECOVER button simultaneously when SINGLE is selected. Otherwise, the setting of the digital disk recorder may be initialized and it may cause a malfunction.

● Procedures

1. HDD power-off procedures

Perform either of the following procedures depending on the installation situations to stop the HDD motors.

Important

If turning off the POWER switch of a unit, the latter units may not work because of interrupted data transmission.

The HDDs should be installed in the proper positions in order as shown above. Do not skip or reverse the order of the HDD positions.

Important

• The position of the MODE switch of all units in a system must be the same.

• When set to RAID5, the digital disk recorder will not access the HDD preinstalled in it, but will access only the HDDs in the extension unit.

• Refer to the dealer for the compatible HDDs with this unit.

• The replaced/added HDDs will be formatted.

SINGLE mode: Only the replaced/added HDD will be

formatted. For example, when the HDD 4 of the extension unit 2 is replaced, only the HDD4 of the extension unit 2 will be formatted.

RAID 5 mode: All HDDs of the extension units will be

formatted when a new HDD is added or a preinstalled HDD is removed. For example, when the HDD 4 of the extension unit 2 is added, all HDDs of the extension unit 2 will be formatted.

• Data readout will not be performed when the HDD positions are changed after once the system has been operated.

Case 1: When the rear of the units is accessible, turn off

the power switches of the digital disk recorder and extension units, then detach all the power plugs from the outlets.

■ Connections

You can connect up to seven extension units with the digital disk recorder (the WJ-HD300 series) as shown below using the supplied serial cables.

Important

• If turning off the power of a unit, none of the connected following units will work because of interrupted data transmission.

• Never use extension cables (locally procured). Be sure to use the supplied serial cables for connection. Do not lay cables in a redundant route. Otherwise, it may cause data transmission error.

• Make a space of 1 U (44 mm) between the units in a rack for ventilation.

• Follow the recommended connection form. Otherwise, it may cause malfunction of the system.

• Physical connections determine the unit number in a system for each unit. Connect units with the recorder in numeric order as shown in the figure. For example, connect the sixth and seventh units to the third unit when five units have been already installed.

• Do not change connections after the system has run. Otherwise, the recorder will no longer recognize the extension units as before. You can change connections only when you can discard all existing data stored in the units.
