 Connection with the Uninterruptible Power System (UPS)
This is an example of connection with the uninterruptible power system (UPS) to be installed to protect from a power outage.
When a signal is supplied to the outage detection input terminals from the uninterruptible power system (UPS), internal pro-
cessing (stops recording safely) will be started to shut off the power supply for this unit.
After completing the internal processing, a signal will be supplied from the outage processing end output terminal to the unin-
terruptible power system (UPS). Then, the power supply to this unit can be suspended.
 Connection of the control output
• When an alarm device such as a buzzer or a lamp is connected, the signal output from Pin Nos. 15 - 18 can be used to
notify the status by sounding a buzzer or lighting a lamp.
• The following example is of a connection with the HDD error output (pin no. 16).

How to Replace Hard Disk Drives
Replacement of hard disk drives is available regardless of
whether the power of the unit is on or off.
The procedure of replacement depends on whether the
power of the unit is on or off.
Refer to the operating instructions for the optional extension
unit when replacing the hard disk in the extension unit.
When replacing the hard disk drive with the
unit power off
Turn off the power of the unit and detach the power plug
from the outlet.
1. Open the connectors cover on the front panel and
remove the fixing screw.
Detach the front panel by sliding it after removing the
screw.
Important:
• Do not detach the cable connecting the unit and the
front panel while the HDD status indicators are still lit or
until 30 seconds have passed since the HDD status
indicators went off.
• Protect the hard disk drives from static electricity.
• Do not stack them, or keep them upright.
• Do not use an electric screwdriver to secure them. 
(Tightening torque: 0.49 N·m {5 kgf·cm})
• Avoid rapid changes in the temperature and humidity to
prevent condensation. (Acceptable change: within
15 °C/h {59 °F/h})2. Remove the connector from the front panel.
Important:
• Do not pull the cable.
• Hold the connector and pull it straight up.
3. Remove two cables connecting to the hard disk drive.
4. Remove both of the hard disk drive units.

• Remove the screws (4 for each drive unit) and pull the
drive units out.
• Avoid missing the screws for reattaching.
* For replacement of hard disk drives, remove the hard
disk drives from the brackets respectively.
5. Make preparations for the hard disk drives.
• Discharge static electricity from your body before han-
dling the hard disk drives.
• Place the conductive bag in which the hard disk drive
has been put on a soft material such as a mat, and put
the hard disk drive with the board side facing down on
the bag to protect the drive from static electricity.
6. Secure the hard disk drives to the brackets respective-
ly.
• Use 4 sleeves and 4 dampers that are supplied for
each drive unit to secure the drives.
• Do not use an electric screwdriver for impact preven-
tion. (Tightening torque: 0.49 N·m {5 kgf·cm})
7. Set all the jumper connectors to the master side.
• Refer to the instruction manual attached to the hard
disk drive for details.
8. Mount the hard disk drives on the extension unit.
• Use the screws that had been removed in Step 4.
• Do not use an electric screwdriver for impact preven-
tion. (Tightening torque: 0.784 N·m {8 kgf·cm})Important:
The identification numbers of the built-in hard disk dri-
ves are assigned as shown below. The following are the
relationship between slot numbers and hard disk drive
numbers.
Slot HDD #1 :HDD1
Slot HDD #2 :HDD2
Slot HDD #3 :HDD3
Slot HDD #4 :HDD4
Make sure to follow the mounting order of hard disk dri-
ves, HDD1 -> HDD2 -> HDD3 -> HDD4.
Failure to observe this disables the hard disk drives
because a digital disk recorder cannot identify the dri-
ves.
9. Connect the cables.
10. After completion of replacement, connect the power
plug to the outlet and turn on the power of the unit.
→The disk configuration menu automatically appears
after starting up the unit.
