SC846B JBOD Chassis Manual
B-12 JBOD Control Board
In a cascaded configuration, the first chassis includes a motherboard and at least
one host bus adapter (HBA). Other storage enclosures in the system must be
equipped with a JBOD control board. This board controls power and provides some
mangement over the chassis components. For more information, see Appendix C
in this manual, or the Supermicro web site at www.supermicro.com.
The SC846B JBOD chassis includes the JBOD control board.
