Hard drives are sensitive to excess vibration. Use care when opening and closing the drawer.

A RAID 1 mirror requires an even number of hard drives.

Drives that will be configured within an array should be the same capacity to provide the greatest storage space efficiency.

NOTE: ACU does not support mixing SAS and SATA drives in the same logical volume.

Installing the hard drives

1.Be sure all I/O bays contain either an I/O module or an I/O blank. The hard drive drawer does not open if I/O bays are empty.

2.Be sure the I/O modules or I/O blanks are fully seated and their handles are in the locked position. The hard drive drawer does not open if I/O modules or I/O blanks are not fully seated with their handles in the locked position.

WARNING: TIP HAZARD! To reduce the risk of personal injury or damage to the equipment, do not extend the hard drive drawers beyond the supporting surface when the unit is not installed in a rack.

WARNING: To reduce the risk of personal injury or damage to the equipment, ensure that only one hard drive drawer is extended at a time.

WARNING: To reduce the risk of personal injury or damage to the equipment, you must adequately support the chassis during installation and removal. It is not secured to the rack frame or mounted on rails.

3.Extend the hard drive drawer.

WARNING: Pinch hazard—Keep hands out of front and rear of chassis when closing hard drive drawers.
