ir8070 connectivity

[Guest]

Hi Guys and Girls,

Ethernet adapter is intergrated into the main controller in the IR8070, however, my customer wants me to install an addtional ir connectivity kit.
i installed an addtional Ethernet adapter through the expansion bus a1.
for testing purposes i can only test the intergrated network connection.
The second connection, i have difficulties testing the connection.

need some inputs, i will appreciate that.

thanks
