Signals Description:
HD_LED_P: Hard Disk Activity LED signal's pull-up to +5V_RUN voltage (510Ω pull-up).
HD_LED_N: Hard Disk Activity LED output signal.
RST_SW_N: Reset Switch GND.
RST_SW_P: Reset switch input signal SYS_RESET#. This signal can be connected to an external momentary pushbutton (contacts normally open). When the
pushbutton is pressed, the pulse of Reset signal will cause the reset of the board.
PWR_SW_P: Power switch input signal, open drain. This signal can be connected to an external momentary pushbutton (contacts normally open). Upon the pressure
of this pushbutton, the pulse of this signal will let the switched voltage rails turn on or off.
PWR_SW_N: Power Switch GND.
FP PWR_P/SLP_N: Power/Sleep messaging LED terminal 1 with 510Ω pull-up resistor to +5V_ALW voltage. Connect it to an extremity of a dual-colour power LED
for power ON/OF, sleep and message waiting signalling. Please refer to Intel
signal meaning.
FP PWR_N/SLP_P: Power/Sleep messaging LED terminal 2 with 510
power LED above mentioned.
Please be aware that the power switch input signal and the reset switch input signal are also managed directly on the carrier board by the two pushbuttons M2 and
M1 (respectively), so it is not mandatory to connect them externally using CN34.

To allow the integration of a COM Express module based system inside a box PC-like, there
is a connector on the carrier board that allows to remote signals for the Power Button (to be
used to put the system in a Soft Off State, or awake from it), for the Reset Button, and the signal
Signal
for optional LED signalling activity on SATA Channel and Power On states.
