Preface
The WJ-HDE400 is an extension unit for the network disk recorder (WJ-ND400), which is sold separately.
Up to 5 extension units can be connected to one network disk recorder.
A maximum of 9 hard disks (hereafter HDD) can be installed in an extension unit and operated as a RAID (Redundant Array of Inexpensive Disks) to increase fault tolerance of the system.
HDD Fault Tolerance System
HDD fault tolerance is high because it is possible to use the RAID function.
This product is equipped with the RAID6 mode that can recover image data when two HDDs fail, in addition to the RAID5 mode that can recover image data (RAID6 has two sets of error correcting code data). This prevents loss of recorded image data on large volume HDDs.
•To use the RAID5 mode you need to connect 3 or more HDDs, the RAID6 mode requires 4 or more HDDs.
•Theoretical volume when RAID5 mode enabled
Theoretical volume = HDD with smallest capacity in the unit x (number of HDDs in the unit −1)
•Theoretical volume when RAID6 mode enabled
Theoretical volume = HDD with smallest capacity in the unit x (number of HDDs in the unit −2)
•The capacity of the HDDs that are installed may be a few percents smaller.
Changing HDDs is Easy
You can install and remove HDDs by opening the front panel of the extension unit.
If more than two HDDs are installed, replacement can be done without stopping recording. Instructions are shown on the LCD to reduce misoperations, and make maintaining and replacing HDDs easy.
Use the special HDD canister provided to install the HDD.
The HDD unit is an HDD that is in the special canister. The HDD units can be easily installed or removed from the HDD bay slots inside the front cover of the extension unit.
* Contact your dealer for information on purchasing and replacing HDDs.
About these Operating Instructions
This manual describes how to install and connect the extension unit. It also describes how to install and remove HDDs by operating the buttons on the front panel of the network disk recorder.
Refer to the manuals provided with the network disk recorder to use the extension unit in a system.

Precautions
zRefer all work related to the installation of this product to qualified service personnel or system installers.
zDo not operate the unit beyond their its specified temperature, humidity, or power source ratings.
Use the unit at temperatures between +5 ºC - +45 ºC {41 ºF - 113 ºF} and where the humidity is between 5 % - 90 %.
The input power source for NTSC model is 120 V AC 60 Hz, for PAL model is 220 V - 240 V AC 50 Hz.
Performance and lifetime of hard disk drives are easily affected by heat (used at high temperature) characteristically. It is recommended to use this unit at temperatures between +20 ºC - +30 ºC {68 ºF - 86 ºF}.
zPOWER switch
The [POWER] switch is located on the rear of the unit. Even though the [POWER] switch is set to "OFF", the power supply will not be cut. To cut the power supply, unplug the power plug of the unit from the AC outlet. When using the power supply control unit, turn off the power of the power supply control unit.
zHard disk drives
Hard disk drives are vulnerable to vibration. Handle them with care.
It is possible to damage them if they are moved while their motors are still running. Do not move them just after turning their power on or off (for around 30 seconds).
A lifetime of hard disk drives is limited by use.
It is recommended to replace them after around 18 000 hours of operation to prevent data loss from disk failures.
Write error may occur frequently after around 20 000 hours of operation and the head and motor deterioration may occur and will reach their lifetime after 30 000 hours of operation when they have been used at the recommended ambient temperature (approx. +25 ºC {77 ºF}).
When hard disk drive trouble occurs, replace it immediately. Consult your dealer for servicing.
Hard disk drives are precise devices. Do not leave them where the temperature is high and humid.
Do not touch the connector of the removable hard disk by hand directly to protect the hard disk drive from static electricity.
Take notice of the following for the removed hard disks.
Do not leave them where the temperature is high and humid. It may cause condensation.
Place them where the temperature is between 0 ºC {32 ºF} and 30 ºC {86 ºF} and humidity is between 20 - 40 % when they are not used for a long time (six months or more). Consult your dealer for further information.
Operate them for around an hour at least once every six months when they are not used for a long time.
When placing them stacked, do not stack more than four disks.
zHeat dissipation
Refer to the following to prevent fire and malfunction of the unit.
Do not block the front and rear for smooth ventilation.
Keep the unit 5 cm {1.97 "} or more away from the both sides and the upper side.
Keep clean the ventilation openings of the unit to prevent overheating.
A lifetime of the cooling fan is limited by use.
zGrounding
Confirm that the wire is connected from the SIGNALGND terminal to earth ground.
A grounding connection must be made before connecting the power plug of the unit to the main power supply.
When disconnecting the grounding wire, make sure that the power plug of the unit is disconnected from the main power supply.
zAvoid placing the unit near noise sources
If the unit is placed near noise sources such as fluorescent lamps, noises may be produced. In this case, rewire avoiding the noise sources, or move the unit to the place far from them.
zPlaces to avoid
Do not place the unit in the following places:
Places exposed to direct sunlight
Places subject to having strong vibration or impact
Near magnetic field sources such as a television or speakers
Place where condensation forms easily, where temperature changes greatly, humid places
Steamy and oily places such as kitchens
Places which are not level
zCleaning
Turn the power off when cleaning the unit. Otherwise it may cause injuries.
Do not use strong or abrasive detergents when cleaning the unit body.
Use a dry cloth to clean the unit when it is dirty.
When the dirt is hard to remove, use a mild detergent and wipe gently.
zIndication label
Refer to the indication label placed on the surface of the unit as to the indications of equipment classification and power source, etc.
zHandle the unit with care.
Do not strike or shake, as this may damage the unit.
zDo not strike or give a strong shock to the unit.
It may cause damage or allow water to enter the unit.
zPlace the unit horizontally on a level surface.
Do not place the unit in an upright position. When stacking multiple units, clear a space of more than 5 cm {1.97 "} from both sides, the top, the bottom and the rear of the units.
zAvoid placing receptacles that contain liquids such as water near the unit.
If liquid spills onto the unit, it may cause fire or an electric shock.
7
zPrevent condensation from forming on the surface of the hard disk.
If this happens, do not turn on the power of the unit and leave the unit for around 2 hours.
Wait until the dew evaporates in any of the following cases:
The unit is placed in an extremely humid place.
The unit is placed in a room where a heater has just been turned on.
The unit is moved from an air-conditioned room to a humid and high-temperature room.
When the unit has not been used for a certain period, turn on the power of the unit (approximately once a week), and perform recording/playback to prevent interferences with functions.
We recommend that you make a note of your settings and save them. This will help when you are required to change the system configuration, or when unexpected trouble or failure occurs.
Distributing, copying, disassembling, reverse compiling, reverse engineering, and also exporting in violation of export laws of the software provided with this product, is expressly prohibited.
