Solved 3.3 volt LED not lighting up on brand new board

[Lupo]

Hello, I just got my first duet wifi, I managed to go through the initial networking setup without issues. Although when I connect it to the 12 V supply the board doesn't work and needs to be plugged in through usb.

Is there a jumper in the I_5V_EN position?

Is the 7.5A fuse intact?

I completely overlooked the jumper, it's now working, thank you very much
