Ubuntu installation on VEP1400

Hello,

I´m just trying to install ubuntu on a Dell VEP 1405 (SD-WAN 600) device. But the NIC won´t recognized. I can use the wlan adapter, but I get no link on the copper or fibre interfaces.  

With the eda Diag-Tool the leds light and I have a link on the interfaces.

I tried also RedHat as an alternative.

Has anybody installed Linux on the VEP1405 ?

Regards,

Alexander
