[but]

So, I've set up many Antminer S9's and curious if I have maybe a couple bad apples?  2 of my miners that arrived power up just fine, have all green lights, but the Ethernet slot does not light up and I cannot acquire an IP.  I've done the troubleshooting 101, reset the miner to default, ensured the network cord works, and the port from my switch is confirmed working. 

There is very limited information pertaining to this problem and curious if anyone has experienced this as well, and possibly found a resolution?  Thanks in advance.
