■Precautions

•Do not operate the appliance beyond its specified tem-

perature, humidity or power source ratings.

Do not use the appliance in an extreme environment

where a 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.

■General

The extension unit WJ-HDE300 can accommodate up to four hard disk drives per unit to add available disk space to the digital

disk recorder WJ-HD316A/WJ-HD309A series. 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 correc-

tion 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 per unit.

When using the RAID function, the 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.

•Avoid condensation on the surface of the HDD.

If this happens, do not turn on the power of the appli-

ance 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 dif-

ferent 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 in a horizontal position.

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 MODE switches of all extension units in a system

should be set to the same position, SINGLE or RAID5.

Otherwise, the system will malfunction.

•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 effi-

cient 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.

!5 HDD power switch [HDD POWER]

Use this switch in the ON position for normal operation.

ON: Supplies the power to the HDDs and the HDD

power indicators will light. Default position

OFF: Does not supply the power and the HDD power

indicators will go out.

!6 Recover button [RECOVER]

Use this button with the RESET button after replacing

the HDDs used in the RAID 5 mode to start data recov-

ery.

Refer to page 12 for details.

■Replacing/Mounting HDDs

Up to four HDDs (locally procured) can be installed in an

extension unit.

Important

•Type of hard disk drive

Consult your dealer about hard disk drives. Use only

hard disk drives compatible with the extension unit. If

unauthorized hard disk drives are used, it may cause a

system error.

It is recommended that the same type drives having the

same capacity should be installed in the extension units

to maximize the usable capacity.

•The HDDs should be installed in the proper positions in

the order as shown above. Do not skip or reverse the

order of the HDD positions. Otherwise, the recorder will

not recognize the extension unit or wrongly mounted

drives.

•The MODE switches of all units in a system should be

set to the same position, SINGLE or RAID5. When

mixed, it will cause a system error. See Troubleshooting

for details.

•When applying the RAID5 mode, it requires a minimum

of 3 drives per unit. When only two drives are mounted

in position #1 and #2, the ERROR indicator will be lit

red, HDD3 indicator will be lit red, and HDD4 indicator

will blink red.

•When applying the RAID5 mode, the digital disk

recorder will not access the HDD preinstalled in it, but

will access only the HDDs in the extension unit.

•Do not change the installed positions after the system

has been operated. Otherwise, data readout will not be

performed

•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 the 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

the HDDs of the extension unit 2 will be

formatted.
