[K12OSN] Networking a new school for K12LTSP?

[John Lucas]

One other consideration when networking multiple buildings: using fiberoptic 
cabling (instead of copper) between buildings would reduce the chances of 
incurring grounding loops. Unless there is a single ground plane for all 
wiring, when there is a short, it will take the shortest path and that could 
be through your network equipment. The chances of one building having a 
common ground plane are much greater than multiple buildings sharing a common 
ground plane; don't import another building's problems. I have learned this 
from sad experience, profit from my folly. It is way expensive to do the 
backbone correctly the *second* time, instead of the first.
