BCA-S : Blind Connect Assembly consisting of four 8482-SFF ports (supporting SAS or SATA drives). The
assembly also contains the following cable connections:

One 4-pin power connector that connect to the motherboard

One mini-SAS HD connector labeled "S/X" that connect to either the onboard Intel
controller or Avago controller

LEDs light up next to each port to show which ports on the BCA are functional and
which drive types each port can support based on the controller(s) the BCA is
connected to.

When the "S/X" cable is connected to an Avago controller, all 4 ports on the BCA are
active and show as supporting SAS and SATA via the LEDs.

When the "S/X" cable is connected to the onboard Intel controller, only two of the
ports on the BCA are active and show as supporting SATA via the LEDs.
