■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 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 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 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 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.
•Avoid condensation on the surface of the HDD.
If this happened, 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 horizontally.

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.

ves for data or error correction information). Default
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 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 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 off.
!6 Recover button [RECOVER]
Use this button with the RESET button after replacing
HDDs used in the RAID 5 mode to start data recovery.
Refer to page 12 for details.

■Replacing/Mounting HDDs
Up to four HDDs (locally procured) can be installed in an
extension unit.
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 exten-
sion unit 2 is added, all HDDs of the
extension unit 2 will be formatted.
•Data readout will not be performed when the HDD posi-
tions are changed after once the system has been
operated.
●Procedures

■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 con-
nected following units will work because of inter-
rupted data transmission.
•Never use extension cables (locally procured). Be
sure to use the supplied serial cables for connec-
tion. 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 recog-
nize the extension units as before. You can change
connections only when you can discard all existing
data stored in the units.

•Make a space of 1U (44 mm) between the units for ven-
tilation, and install them in the rack as low as possible.
•Keep the temperature in a rack below 45 °C (113 °F).
•Install a fan in the rack when the ambient temperature is
above 30 °C (86 °F).
•Do not block the ventilation openings or slots on the
cover to prevent the unit from overheating.
