HDD unit

Handle the HDD units

To install a hard disk drive in the extension unit, it is necessary to assemble an HDD unit (encase the  hard disk drive in the HDD canister).
The HDD unit is designed to easily install/remove the hard disk drive in/from the extension unit. Contact your dealer about purchasing, installing, and replacing the hard disk drives.

Important:

• The HDD unit is a precision device. Handle them with care. Vibration and shocks may cause failure of the HDD unit.
• Before transportation, read “HDD unit holding bracket” (this page) and “When you transport the extension unit” (☞ Page 21).
• Do not move or install this product just after turning the power on or off (for around 30 seconds.) The hard disk drives are running.
• Install the HDD units in order starting with disk slot 1.
• Once the operation has started in RAID1, RAID5 or RAID6* mode, do not change the position of the HDD unit. If they are changed, it may become impossible to read recorded data.
• Refer to Operation/Settings of the Operating Instructions for RAID mode.

HDD unit holding bracket

The extension unit has the “HDD unit holding bracket” in the HDD unit slot, screwed in at the factory before shipment. To install the HDD unit in the extension unit, remove the “HDD unit holding bracket” first.
The “HDD unit holding bracket” and the screw for fixing the bracket are necessary to prevent the HDD unit from falling off during transportation. Keep them properly

Assemble HDD unit

To install a hard disk drive in the recorder, it is necessary to assemble an HDD unit (encase the hard disk drive in the HDD canister).
The HDD unit is designed to easily install/remove the hard disk drive in/from the recorder. Contact your dealer about purchasing, installing, and replacing the hard disk drives.

Important:

• Hard disk drives are precision devices. Before installing the hard disk drives, read the “Hard disk drive” section of Precautions in important information together with the following.
• 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.
• Use an anti-static mat and an anti-static grounding strap when installing/replacing the hard disk drives.
• When installing hard disk drives, use a low-torque powered screwdriver or a torque screwdriver to tighten screws with the specified torque.

Step 1
Fix both sides of the hard disk drive with the dedicated HDD canister using the 4 provided screws for HDD canister installation.
Tightening torque for the screws: 0.49 N·m (5 kgf·cm) (use a low-torque powered screwdriver or a torque screwdriver)

Step 2
Fix the bottom of the hard disk drive with the HDD canister using the 2 provided screws for HDD canister installation.
Tightening torque for the screws: 0.49 N·m (5 kgf·cm) (use a low-torque powered screwdriver or a torque screwdriver)

Important:

• To use 5TB, 6TB or more capacity of HDD in the future with HDD canister, please do not fix two provided  screws into bottom side. Because the screw length is longer than depth of tapped hole of HDD.
