Steve, does the 3am Ubnt fat girl look like this?

with Cambium Sync is muy bueno.

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.

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

I presume that means the POE power supply. So try

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).

Wash out the jacks extra good too.
If they have not had too large of a

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?
