B-9 JBOD Control Board
In a cascaded configuration, the first chassis (head node) 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 SC216 JBOD chassis includes the JBOD control board.
