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. From: Gino A.

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. From: Gino A.

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

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. -Sean On Thu, Sep 26, 2019 at 8:45 AM Gino A.

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?
