I am new to this part of Radio Reference. When I tried to zoom in, it only goes one step and not much improvement. I probably should have copied to pictures and used ACDSee to magnify the image. I did not see anything in the posts about the cables. Probably missed it as it was late and I tried to read without my glasses.
It may be a transceiver for wireless internet, that might explain the ref/green leds. I have wireless and they use Motorola Canopy. The transceiver is mounted to a pole to clear trees (it is 5GHz). Its output is Ethernet. Inside is the end of the cable and a wall wart with an injector
module. They did not put any leds on the transceiver to show the status as it is duplex, both leds would be on. Mine is now a medium rectangular off white box. Probably has a panel antenna inside.
That is one heavy ground lead. Do you have thunder storms with lightening in high quantity?
I would do a search for Wireless Internet equipment, there are a few. Actually I have as it is in the license free band and would make some of the long run of cables that get high induced voltage. One strike nearby (bright blue light and an immediate very loud crack) a pop came from the computer and no Ethernet port. And, the cable has two manufactured for the purpose lightening suppressors for Ethernet lines. The problem is, the pole is 125 feet from the house. The two grounds are not connected and the house one is not tied to the ground for the power coming in to the house. I should not have read the book Motorola has on meeting all of the government agencies specifications. It shows diagrams on how to install the grounding system. It is too bad that some sub-contractors do not go "by the book" and make a lightening magnet.
I am going to do grounding properly at the house I buy in SC. Might even put a halo in the attic.
