why am I seeing three ethernet ports for PXI

[sumanth22]

The PXI has only two ethernet ports but on NI_MAX it is showing me that it has three ports? I have attached the screenshot of the screen. 

Please help!

FYI

both Host computer and PXI has ethercat drivers.

Did you use any Ethernet PXI card? If not, can you format and re-install the PXI?

Thanks for the response..

No.. I do not have any external ethernet modules connected expect ethercat.. I tried reinstalling the PXI it didn't work.. Please let me know if you have any other suggestions?

I unplugged the Ethernet cable from port 2 (port where ethercat is connected) and did format and reinstall 2 times.. then it is working fine now... thanks for the response..
