No, I would rather them fail open than closed.  At least you have a chance to 
keep service rolling that way.

I think it’s bad for the GDTs also if they just sit there conducting until you 
roll a truck.  Depending on the amount of power they are dissipating.  Like 1 
amp with an arc voltage of 10 volts would be 10 watts.  If on the other hand 
the POE shuts down and keeps cycling trying to come back up, the arc will go 
out and the GDT will reset to a non conducting state.

 

I read somewhere there are special GDTs with a mechanical shorting clip that 
kicks in if the GDT gets too hot.  I don’t think Chuck uses those though.

Well, you could short it out and see what happens...

 

Most PoE bricks (like the kind that come with Cambium SMs, Ubiquiti, etc.) seem 
to be able to hand brief shorts just fine without damaging anything... on a lot 
of them the power light will blink if they're shorted. I don't know about the 
higher powered kind of stuff like would come with licensed radios, since I 
generally try to be a bit more careful with that sort of thing. I'm pretty sure 
anything that's 802.3at/af will be fine.

  I assume you are referring to the fact that the Netonix POE will supply 
enough voltage and/or current to keep the GDT arc alive once a lightning strike 
has triggered it.  While the Packetflux soft fuse will trip, interrupt the arc, 
and then reset itself.

   

  So my question is about other types of POE, like those used for licensed 
radios.  Either a regular brick type POE, or something like the Cambium/Ceragon 
outdoor DC powered POE.  Should we avoid using the Cat6/GDT surge suppressors 
with those and instead use a GigE-HV model?

  No.  No surge suppressor will work with Netonix.  

  Once they fire they short out the line and Netonix poe circuit will croak.

   

  That is why we created the ethernet fuse products.  

   

  Netonix really needs to take a chapter from the Packetflux book of how to 
design POE.

      Damn it Mathew! 

       

      I really can't quantify the surge cards have or have not helped.  I can 
say, though, where we have them it's definitely not hurting.  I'd really prefer 
to have one card to make it simpler as well.

        I started using the CAT6 for pretty much everything, unless it's a site 
where I've had problems with lightning damage in the past. It's just simpler to 
not have to worry about which one to use with which radio, and they're a bit 
cheaper, so that's nice too.

Surge suppressors that use solid state components exacerbate this problem.

created the CAT6 100% Gas Discharge Tube line of products to prevent these 
errors on Cambium.

           

          They fire a bit slower than a solid state surge suppressor but are 
very robust.  As popular as they are, I presume people are starting to use them 
on everything.  Personally I would use the GIGE line everywhere I could as it 
does offer better protection.
