■ 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 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 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.
■ 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 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.
• Avoid condensation on the surface of the HDD.
If this happens, 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 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 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 Setup Procedures 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 Setup Procedures 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

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.
HDD 4
HDD 3
• 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.
● Procedures
1. HDD power-off procedures
Perform either of the following procedures depending
on the installation situations to stop the HDD motors.
Case 1: When the rear of the units is accessible, turn off
the power switches of the digital disk recorder
first, and turn off extension units.
• 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
POWER
Case 2: When the rear of the units is inaccessible, for
example when mounted in a rack, open the
SETUP MENU of the digital disk recorder and set
the
HDD SAFETY MODE to ON. The extension
units will turn to the HDD power-off mode.
Refer to Setup Procedures of this manual and the
