Determine the operational mode of the hard disk drives It is possible to operate the recorder with the RAID function that is known as the HDD fault-tolerance system by installing an optional RAID board. Refer to the operating instructions of the RAID board for how to install the RAID board. The following operational modes are provided to the RAID function of the recorder. RAID 5 mode: it is possible to recover recorded images even when a single hard disk drive becomes faulty. RAID 6 mode: it is possible to recover recorded images even when 2 hard disk drives become faulty. Proceed as follows to switch the operational mode of the RAID function. Step 1 Turn off the power of the recorder. (☞ Page 55) Step 2 Detach the front cover. (☞ Page 21) Step 3 Determine the operational mode using the [RAID] switch.
