3.3 System
A number of signals for system control and for SMBus communication are provided through a 2x12 pin
connector (FCI 98424-G52-24LF, mating connector FCI 90311-024LF). This connector combines signals
for power button, reset, keyboard, speaker, and several LEDs such as harddisk LED, and suspend LED,
and three additional LEDs which are driven by GPIOs. Of these three GPIO-LEDs, LED1 and LED2 are
already provided with a series resistor. SMBus capable devices can also be connected.
