PWR LED
POE Header
If compute modules is awake RUN_PG will be high so the button doesn't do anything
If the compute module is asleep then RUN_PG will be at 0v and so pull global enable low
Activity LED
40Way GPIO Header
A button bwteen pins 13-14 can be used to wake up compute module from power down
