What they offer is a PoE switch that is compatible with the non-standard
PoE types we use in this business. If you were installing a switch
anyway, then it saves you from having a separate switch and midspan PoE.
.....that said I've never used one. I can't comment on quality.

That is why I build the POE fuse product. It does blow fast
enough to protect the switch.

Chuck,
We have had really good luck with putting PTC fuses in front of
the POE power on the Mimosa radios in order to avoid blowing the
fuses in the rectifier shelf when the gas tubes in the Mimosa
short the POE. I’m thinking maybe you want to look at putting
some of those on the SS for the power coming from the Netonix?
Let the gas tubes (or whatever surge suppressor you are using)
short all the lines together and let the PTC fuse cut the power
briefly? Might be a little tricky to get the values right but
might be able to save the POE from blowing.
Or talk Netonix into including them internally so that they
survive a POE short circuit.
For those of you scratching your head… we routinely power Mimosa
B5’s using Packetflux DC injectors from the -48V rectifier. The
surge suppression in the B5’s will short the power supply during a
surge event long enough to blow the 2 or 5A telecom fuse. All
the equipment lives but we have to go replace the fuse - which we
don’t want to do since it causes an outage until we get there.
The PTC fuse inline avoids the fuse blowing.

Netonix ports will blow if they are shorted.

Should only be 24v. Even if it doubled, should be OK on the
radio and surge card.
What's the Netonix problem?

Kinda the reverse of the Netonix problem.

I replaced the POE, AP, and surge card on Tuesday. That's what
fixed it for sure.
The AP is sitting here in the lab and doing gigabit for 3 days
now, happily. The POE and surge card are in the trash.
I'm wondering if it's possible the POE fried all of those surge
cards on Saturday/Sunday/Monday/Tuesday. If that's possible?

Well there was no lightning or anything, beautiful weather.
After several cards I have to imagine it's the POE or the AP.
We replaced those two at the same time.
Does it make sense the POE was doing something weird to fry
them or more sense the AP was pulling too many amps? AP seems
perfectly fine in the office for 36 hours, so I'm inclined to
believe it's the POE.

How long does it need to be cold for it to be self reset?
The one I took down this morning looks perfectly clean and I
can't get pins 7/8 through it. At this point I'm thinking
the (AC) POE is the cause of all our issues (Cambium, so that
pair is positive 24v and data).

That will remove any water. Need to make sure there is no
corrosion.
Wash out the jacks extra good too.
If they have not had too large of a surge, they are totally
self resetting.

There's a cause and I'm pretty confident it's not the cards
themselves.
This weekend an AP started having eth link issues. Look at
it and the card/rj45 is full of water. Replaced the line.
Problem returns about 12 hours later.
I plug in my continuity tester and pin 7 blinks quickly and
fades away. Headed up the tower now for a new AP and already
did a new Poe (no power until AP replaced).
Is it possible the Poe/AP are damaging the surge card? We've
gone through 5-6 cards since Saturday, and I thought it was
all water related. It stopped raining on Sunday after card
3 + new line.
Any other ideas? Can I wait a minute and reuse the dry
cards, are they self resetting (I tried power cycling the
POE for 5 seconds with no change) after a length of time?
