■ Handle the hard disk drives The HDD units can be easily installed/removed in/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 extension unit. 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.

The HDD units can be easily installed/removed in/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 extension unit. 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.)
