DC IN allows you to supply 12V via the Pins rather than over the USB C. This could be useful if you have a 12V /3A PSU but its not got a USB C plug, or you do not have a USB C hub with pass through or if you are using it inside something else and its easier to power it direct, than the USB C
See the image below for polarity.
RST_SW (and PWR_SW below it) are RESET and POWER SWitches like on many PC’s. You can see what makes the two pairs up as connections highlighted in the image.
If you short the RST_SW connection while its running the Blade will reset.
If you short PWR_SW when the blade is running it will make it do whatever is set in the power options, that could be power off, hibernate, suspect or do nothing.
If the Blade has power but is not actually running (say after a shutdown/ suspect or hibernate) command then shorting PWR_SW should make it start up.
