false start with KC868 A16 v3

[PhVdP]

Hi,

I received the KC868-A16v3; wired as documentation, powered it on, flashered it with latest firmware, changed the USB cable                     ... but it's not working : only a red led is lighting, no ethernet connection setting (green light on the board, orange light on the router). I've tried with another usb cable, pressing buttons reset/rebootable during power it on... Still impossible to connect. I've tried with Putty and serial communication with the USD cable; without success...

Any idea is welcome.
