Galaxy A16F-R2431 Installation and Hardware Reference Manual
1.3.3
MUX Kit
P/N:
The MUX kit facilitates the installation of SATA-II hard drives in the dual-
controller subsystems. The subsystem comes with MUX-enabled drive trays
as standard parts. Separately purchased and independently installed SATA
MUX kits or MUX-enabled drive trays are also available as spare parts.
When installing disk drives into drive trays, the connectors at the back of
disk drives must be properly mated to the SATA connectors of the MUX
kit. When installed into the enclosure, the SATA connectors on the MUX
kits will mate with the corresponding connectors on the backplane board.

TIPS:
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 two members destroys a RAID6 array.

NOTE:
The MUX board facilitates cross-controller access to an individual
disk drive and therefore is a necessary component for the A16F-
R2431. All drive trays come with the MUX board.
