What's flashing inside a NUC?

ROCK running on a Cirrus7 (NUC NUC8i7BEH inside) and working great indeed :slight_smile:

just… what’s flashing, now and then, inside it? :no_mouth:
can see it through both USB ports on power switch’s side


Maybe you are referring the the Ethernet port led?

I thought too it may be ethernet LEDs, even though those flashes I see are very bright
will try placing a mirror in front of ethernet port’s side to check if that’s it
