sbRIO-9642 connect with PC by Ethernet

I am using sbRIO-9642 connecting PC by Ethernet

I can find my device in the MAX as following:

It is always shown as "No configured".

And I used command window to show all the devices connected with my PC as following:

I can't find the device with MAC address: 00:80:2f:13:84:76

How to solve this BIG problem, it's a bit annoying!

Thanks a lot
