To be fast enough it will either have to be fuses or it will have to be expensive.

Changing your surge suppressor is a good idea, but I think PoE devices ought to include short circuit protection anyway. ------ Original Message ------ From: "Chuck McCown" <[email protected]> To: [email protected] Sent: 3/25/2017 9:28:51 AM Subject: Re: [AFMUG] Fw: Netonix If an impulse comes along and the surge suppressor clamps to ground, you run the risk of smoking the Netonix POE transformer. It will not protect itself against shorts. From: Josh Baird Sent: Saturday, March 25, 2017 7:23 AM To: [email protected] Subject: Re: [AFMUG] Fw: Netonix What exactly is the reason? We always run through your surge protectors before connecting to Netonix.

We accidentally hooked up an AF24 through a Cambium surge suppressor, and it fragged the port on the Netonix. We were swapping from something else that had been on the cable, and completely forgot that it was going through that surge suppressor. Hard lesson learned. bp <part15sbs{at}gmail{dot}com> On 3/24/2017 1:27 PM, Chuck McCown wrote: OK, had an exchange with Netonix today. It is just as Matt Hoppes said. You short out their POE and it will blow the Ethernet transformer. I really presumed they had circuitry like Forrest that could detect and shut down in an over current situation. They do have poly fuses which are slow to react and may protect it from a very brief short, but longer shorts will indeed harm the port feeding the transformer. So, Netonix is not active POE. I would say that on passive POE a plain surge suppressor should not be used. I am working some “non plain” surge suppressors now.... ;-) Stay tuned to this bat channel and a big thanks to Matt for forcing me to learn something new. It was painful, but I can do painful things when I have to.
