Intel® IQ31244 Customer Reference Board
5.3Activity LEDs
The IQ31244 provides a group of four sets of headers for each SATA controller located on the bottom-left corner of the board. Each set of headers represents a cathode and anode of an LED for each port of the SATA controller. The SATA activity can be shown through a LED when it is connected to the headers. The activity of the SATA controller can displayed in two modes. In DPA mode, each port has its own LED signal. The group of headers (J16, J17, J18, and J20) are assigned to each SATA controller (U27, U28, U29, and U30). Z12 is the header for congregated SATA LED signals. Pin 1 is the cathode and pin 2 is the anode of the LED. The LED symbol is shown on the board.
