[K12OSN] OT building to building ethernet wiring

[Jim Hays]

Cat 5 in conduit is not fine, unless you like buying new switches on 
each end every time there is a thunderstorm.  You simply can't run 
copper between buildings unless you are quite sure that the cables are 
properly grounded and the equipment on each end is as well.  You will 
actually save money (and innumerable headaches) by running fiber (or 
using wireless).

To paraphrase what someone else wrote earlier, "Do NOT run copper 
between buildings!!".
