Setup 19
• 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.
