A disk expansion unit is an exclusive device that can install up to 14 hard disk drives. (The number

An optional cable may be required to connect with a disk expansion unit. Refer to the manual

expansion unit in a RAID System (RAID0, RAID1, or RAID5). For details on settings and the
setting methods, refer to the manual provided with the board.
While a disk expansion unit is set in a RAID System, you can use the "Auto Rebuild" feature of the
N8103-90 Disk Array Controller to restore data if one of the hard disk drives installed in the disk
expansion unit fails. (Replace the failing hard disk drive while the power is on. (Hot swapping))
IMPORTANT:
