Important
• Changing the MODE switch will not be accepted when
the ERROR indicator lights red and/or when HDD 1-4
indicate a system error status by lighting red and
orange. When this happens, ask your dealer to solve
the error.
• When set to RAID5, the HDD preinstalled in the digital
disk recorder will not work. Instead, it is applied only to
the HDDs installed in the extension unit and the digital
disk recorder will perform storage and readout of the
image data by accessing the extension unit.
• The MODE switches of all extension units in a system
should be set to the same position, SINGLE or RAID5.
Otherwise, the system will malfunction.
• The available disk space of the unit can be logically
calculated as follows. The actual space may be several
percent lower than you calculated depending on the
HDD type used and their combination. The most effi-
cient way is to use the same type drives.
When SINGLE is selected, it will be the sum of all
the HDD sizes.
When RAID 5 is selected, it will be as follows.
When 3 HDDs are in the unit: It will be double the
size of the smallest HDD size.
When 4 HDDs are in the unit: It will be triple the size
of the smallest HDD size.
For example, if 4 HDDs of 80 GB, 120 GB, and two
160 GB are mounted, the available disk space will
be 80 G x 3 = 240 GB.
!5 HDD power switch [HDD POWER]
Use this switch in the ON position for normal operation.
ON: Supplies the power to the HDDs and the HDD
power indicators will light. Default position
OFF: Does not supply the power and the HDD power
indicators will go out.
!6 Recover button [RECOVER]
Use this button with the RESET button after replacing
the HDDs used in the RAID 5 mode to start data recov-
ery.
