[Electrical] Re: Need help with surge/lightning damage

All of my switches have SFP modules so I could do fiber directly. Will have to look into that for sure as it would remove the issue completely.

Fiber is a great way to harden your system to lightning.

In regards to what Jack_in_VA See Profile posted surge protection does not absorb and dissipate transient energy, it diverts it. That is why proper grounding and bonding is so critical. Ohms law and AC impedance conspire to create large voltage difference over of few feet of ordinary conductors during surge events. This difference in potential is what lets out the magic smoke of your expensive electronics.

Depends which issue we're talking about. It will not prevent stuff from getting blown; my equipment got fried with a 6' network cable...

True, I'm talking about the issue of EM inducting into the long runs and needing the entrance protectors on each end of the circuit. If I switch to fiber, that issue goes away completely.
