I'm getting it now. They are trying to figure out how to get the signal in. Probably trying to align the router Mac to the server. The router has 3, 1Gb Ethernet ports and 1, 2.5Gb port. So you will need. Switch coming out that one lan port. I'm pretty sure it's 3BB server vice AIS. Ill know more after it's running. 3BB guy just got back.
