I need help in understanding a product failure.
I have now had two customers with similar failures in my POE fuse product. The
fuses are blowing.
So far it is limited to the fuses on pins 4/5.
One customer is using:
UBNT 5AC Prism Gen 2 radio, Mikrotik 411 boards, using both poes and netonix
The Prism Gen 2 uses "standard" UBNT passive 24v POE. +4,5 -7,8. I've
seen netonix switches claiming as much as 12 watts draw from one when
running. I wouldn't be surprised if their startup draw may be a bit higher.

No, that is not true, it adds an additional ground on 3&6. So to obtain a
gigabit connection you have + on 4&5 and - on 3&6, 7&8. All of the present
day UBNT gear is like this since they added gigabit Ethernet. When we
upgrade we add a jumper to 3&6 to get it to negotiate at gigabit, but they

This is the part that confuses me. If powering with a Netonix, there is no
setting for 'add a ground on 3&6', yet somehow it works and maintains a
gigabit connection when powering these devices. Perhaps they found that
they could ground 3&6 on legacy devices as well and it would still work
fine?
If that's right, would that mean 0.5amp on 4&5 and 0.25amp on 3&6,7&8 ?
Is it a 0.5amp fuse?

I started graphing the epmp satellites visible and tracked. Visible is
always above 7 with an average of 12.44. However the tracked dips down to

polarity... As long as there's a pair with negative and a pair with
positive, they'll turn on. I don't see that ubnt adding a second negative
pair will really affect anything, unless netonix did that as well.

Any polarity or any pinout? Pretty sure the Ubnt AirMax NanoBeam 25dbi
units will do gigabit but only do the old fashion 24v 45+ 78-. Reverse
polarity seems awfully sketch to me.

I have always used exeltech but I am really curious as to what other options
may be out there too.
I also need to be always online. I build a transfer switch that cuts in
commercial power if the inverter fails.
That was pretty easy.

.375 amp per wire. So .750 amp per pair.
At least that is what I think I finally settled on.

So if the variable width font you are using already includes the proper
amount of space after a period, about 1.5 "spaces", when you add an extra
space after a period are you really putting 2.5 "spaces" after the period.

Stop worrying about typeface/font. Just remember:

If you fall for the "single space between sentences" rouse, you will
need to rely on context to differentiate a sentence ending, vs. the

Spacing is pretty important. Tell me what this means:

I think we can all agree that when you read something, the way it displays to
you should have more space after a period at the end of a sentence then between

That's what I thought, until somebody told me otherwise... I think I tested

that they will work with the Cambium pinout though. I remember testing a
few different modules, but the only ones I remember for sure were the old

The new ePMP gigabit interfaces will work both polarities. You can
actually use the old PMP100 power supplies with no issues that I have had
