The WJ-HDE400 is an extension unit for the net work 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 is high  because it is possible to use the RAID function. 
This product is e quipped 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 t wo 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 re quires 4 or more HDDs.
 Theoretical volume  when RAID5 mode ena bled
Theoretical volume = HDD  with smallest capacity in the unit x (num ber of HDDs in the unit −1)
 Theoretical volume  when RAID6 mode ena bled
Theoretical volume = HDD  with smallest capacity in the unit x (num ber of HDDs in the unit −2)
 The capacity of the HDDs that are installed may  be a few percents smaller. 
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 show n on the LCD to reduce
misoperations, and make mainta ining and replacing HDDs easy.
Use the special HDD canister  provided to install the HDD. 
The HDD unit is an HDD that is in t he 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 informati on on purchasing and replacing HDDs.
This manual descri bes how to install and connect the ex tension unit. It also describ
es how to 
 install and remove HDDs  by operating the  buttons
on the front panel of the net work disk recorder. 
Refer to the manuals provided  with the network disk recorder to use the extension unit in a system.

ºF} and  where the humidity is  between 5 % - 90 %.
The input po wer 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 temperatur e) characteristically. It is
recommended to use this unit at temperatures betw een +20 ºC -
+30  ºC {6 8 ºF -  86 ºF}.
z POWER switch
The [PO WER] s witch is located on the rear of the unit. Even
though the [PO WER] s witch is set to OFF, the po wer supply will
not be cut. To cut the po wer supply, unplug the pow er plug of the
unit from the AC outlet.  When using the po wer supply control
unit, turn off the po wer of the power supply control unit.
z Hard disk drives
Hard disk drives are vulnera ble to vibration. Handle them  with
care.
It is possi ble 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 recommen

ded to replace them after around 1 8 000 hours
of operation to prevent data loss from disk failures.
W rite error may occur fre quently 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 am bient
temperature (approx. +25 ºC {77 ºF}).
W hen hard disk drive trou ble 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 remova ble hard disk by
hand directly to protect the hard disk drive from static
electricity.
⋅ Take notice of the follo wing for the removed hard disks.
⋅ Do not leave them w here 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 ti me (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.
⋅ W hen placing them stacked, do not stack more than four
disks.
z Heat dissipation
Refer to the follo wing 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 a way 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.z
Groundin
g
Con
 firm that the  wire is connected from the SIGNALGND
terminal to earth ground.
A grounding connection must  be made before connecting the
pow er plug of the unit to the main power supply.
W hen disconnecting the grounding  wire, make sure that the
pow er plug of the unit is disconnected from the main po wer
supply.
z Avoid placin g the unit near noise sources
If the unit is placed near noise  sources such as fluorescent
lamps, noises may be produced. In this case, re wire avoiding the
noise sources, or move the unit to the place far from them.
z Places to avoid
Do not place the unit in the follo wing places:
⋅ Places exposed to  direct sunlight
⋅ Places su bject to having strong vi bration or impact
⋅ Near magnetic field sources su ch 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
z Cleanin g
