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.
• 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
