Pixhawk LED Definitions?

mlapaglia,
Yeah I have looked high and low for those and can’t find them either. The moderator didn’t read your post carefully. You are not talking about the main LED, which is confusing enough, but are asking what are the 5 LEDs at the other end of the face of the Pixhawk. They are explained nowhere. There are 2 LEDs under FMU and 3 under IO. Pwr means power and is supposed to be green and on all the time under both categories. Both categories have B/E and I can not find any information on what the hell B/E means, what the lights should do, anything! On mine if I am under USB power and plug in a battery the B/E under FMU glows amber but seems dim. Both B/E seem to only be Amber and flash when I start the Pixhawk. Finally the third on below IO is Act which I think means activity and is Blue. I flashes all the time. Just a steady flash.

Moderator, Please note we are talking about the “other” LEDs on the face. By the way the content of the video you referred to is almost all the connectors and doesn’t explain the “Main” LED very well. It needs redone.

My problem with wanting to know about the “other LEDs” stems from my Pixhawk not loading the firmware and my Safety Switch flashing 4 times which means “IO not armed” — And? What do I do? How do I arm it? Help. Help. HELP, Please.
