Handle the hard disk drives
The following are descriptions of how to install/remove the hard disk drives, to determine the operational mode, and to replace a
faulty hard disk drive when operating in the RAID mode.
The hard disk drives can be easily installed in or removed from the HDD slots inside the front cover.
Contact your dealer about purchasing, installing, and replacing the hard disk drives.
Important:
• Hard disk drives are precise devices. Note the following when handling them.
• They are vulnerable to vibration. Handle them with care.
• Before touching a hard disk drive, release static electricity from your body using an anti-static grounding strap, etc. Even after
releasing static electricity, hold the side of the hard disk drive when carrying it.
• To prevent damage to the hard disk drive from static electricity, do not touch the circuit board and the connectors of the hard
disk drive.
• Contact your dealer for further information about hard disk drives compatible with this recorder.
Operation using a hard disk drive that is not recommended is not guaranteed under any circumstances.
• When using multiple hard disk drives, use the same model.
If different models are used together even when the capacities of them are the same, the available capacity may be a few percent
smaller.
• Insert the HDD units one by one in order starting from HDD1.
(The leftmost slot of the HDD slots is HDD1 and the rightmost one is HDD9.)
• Once the operation has started in the RAID 5 or RAID 6 mode, do not change the positions of the HDD units.
If they are changed, it may become impossible to read recorded data.
