Sam, it is two or three desk top computers in a rear building, and a server/switch in the main building. The distance is 110 feet. It's working fine and has been for 10 years.
I was originally concerned about the maximum number of splices (66 block connections) that would work.
The buildings are powered by all new electrical service, installed by me.
There are 4, 3" rigid conduits in concrete between the buildings.
I appreciate all the advice about questions that may come up in the future, but for right now, I just wanted to hear from guys who have had success in using a total of 4 interconnections on a 100 Base T network.
