convenient release button ensures fast and efficient drive swapping.
There are screw holes on the sides of the drive tray for securing hard
drives to the drive tray.
WARNING!
Be careful not to warp, twist, or contort the drive tray in any way
(e.g., by dropping it or resting heavy objects on it). The drive tray
has been customized to fit into the drive bays in the subsystem. If
the drive bay superstructure is deformed or altered, the drive trays
may not properly fit into the drive bay.
Drive bays are arranged as 4-bay wide and 3-bay high. The drive
bays are numbered from Slot 1 to Slot 12 (see the figure below),
from left to right, and then from top to bottom.

.
NOTE:
Tray numbering sequence is important if one disk drive fails and
needs to be replaced. Replacing a wrong drive can fatally fail a
RAID3/5 array. Failing three drives destroys a RAID6 array.
1.3.3 MUX
Kit
The MUX kit is a pre-installed item for the drive trays on the dual-
controller model: S12F-R1432. It enables partner RAID controllers to
access individual SATA-II hard drives in a dual-controller
configuration. If the SAS hard drives are preferred, there is no need
for a MUX kit on each drive tray.
