■ Replacing/Mounting HDDs
Up to four HDDs (locally procured) can be installed in an
extension unit.
HDD 2
HDD 1
The HDDs should be installed in the proper positions in
order as shown above. Do not skip or reverse the order of
the HDD positions.
Important
• The position of the MODE switch of all units in a system
must be the same.
• When set to RAID5, the digital disk recorder will not
access the HDD preinstalled in it, but will access only
the HDDs in the extension unit.
• Refer to the dealer for the compatible HDDs with this
unit.
• 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 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 exten-
sion unit 2 is added, all HDDs of the
extension unit 2 will be formatted.
• Data readout will not be performed when the HDD posi-
tions are changed after once the system has been
operated.
