Unable to use Ethernet port 1 in ONX CATV units to run an Ethernet test after updating to software version 3.8.6

Knowledge Base - FAQ

I am unable to use Ethernet port 1 in ONX CATV units to run Ethernet tests after updating to 3.8.6, what do I do? 
Changes were made to the Ethernet applications in 3.8.6. You need to use Ethernet Port 2 to run Ethernet Tests, or go to System -> Network -> and select "Network Off" to continue using Ethernet Port 1 for Ethernet Tests.
