If you use shielded cable, it offers RF shielding without being grounded. If
you ground one end it offers RF and electrostatic shielding (good for mic
cables etc). If you ground both ends it offers RF, electrostatic and magnetic
shielding (cancels out power line interference).
But grounding the shield also can set up a ground loop which can cause
problems.
Surge suppressors don’t use the shield to do what they do. They do have (mine
anyhow) has shielded jacks so that if you use shielded plugs the shielded will
be bonded to the ground lug.
Some folks thinks this is necessary, others don’t even run shielded cables.

If we skip the SS, Would grounding the shielded cat5 de needed?

I would never use any kind of surge suppressor on a Netonix product that is
making POE.
It is the POE that blows.
But that is why I made the POE fuse products. We sell a small quantity each
month. Zero feedback as to whether they are doing the job.
We have had people claim the fuse was defective when in fact they blew it. It
is not a circuit breaker nor is it a poly fuse. It is an old fashioned one
time use fuse for each of the 4 circuits on an ethernet cable.

So Chuck, whats your take?
No SS if no fuse available?

They are wonderful switches. And they will fix blown ports for $20. I am
surprised they have not adopted Forrest’s method of avoiding this issue.

I dont understand how netonix has such widespread use with the constand
issues i read about. are they just that cheap? low heat production? what is it?

We switched to packetflux rack injectors and planet switches because the
netonix had such a high failure rate.
Knock on wood it’s been a rock solid solution.
But if you are using the netonix you need both the fuse card and grounding
card from mcowentech.

So we have had lots of issues with blow radios recently during storms.
I do know that we are possibly causing them because we are using McCowns
SS with Netonix switches.
So our long term plant is to fuse them, but in the meantime, should we
connect the radios directly to the Netonix switches?
Should we ground the shielded cable shield or would the grounding of the
radio would suffice?
