Netonix is a fantastic product. Give me a few weeks and we will have a fix for this.

We had AC Power supply failing. We had a defective Arfiber 5x powered by Netonix 24V. This took down the whole 24V chain of this Netonix switch and causes the switch to reboot. We had some fuse blows at sites this did not happen before using normal poe power supplies. This happened without lightning event. Chris says this is poor grounding. We see Netonix changed something to resist better with „poor grounding“. So we might use separate Switches for backhauls or just go back and connect backhauls with poe injectors directly to the tower router. I do not like when a single bad cable is able to take down the whole site. We’ll see what Mikrotik does. They will do some announcements end of this month. I see their new POE devices are gigabit and power 24 or 48 if you feed them with the appropriate voltage. If they do a capable tower router with poe we might need no switch at all … Von: Af [mailto:[email protected]] Im Auftrag von David Coudron Gesendet: Samstag, 25.

We will be building out 10 new towers in the next few months, and will be making the change to Netonix switches (we had previously used a different type of switch). I the past we had put Transtector surge protectors on the tower top and in the cabinet on the ground. From what you are saying in thread, we should not plan on surge protectors in the cabinet, but what is the recommended change for the tower top, if any?

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.
