Auto Power-on Select
JP25 is used to select the method of powering on the system. If you want the system to
power-on whenever AC power comes in, set JP25 pins 2 and 3 to On. If you want to use the
power button, set pins 1 and 2 to On.
When using the JP25 “Power On” feature to power the system back on after a power failure
occurs, the system may not power on if the power lost is resumed within 5 seconds (power
flicker).
JP11, JP14, JP15, JP27, JP28 and JP29 are used to select the power of the USB ports. Select-
ing +5V_standby will allow you to use a USB device to wake up the system.
