I'm looking for some technical information regarding the 4 pair and 2 pair only ports on the Netonix switches. I'm specifically interested in the WS-6-MINI but also the other examples.
I'm looking into whether a Mimosa G2 PoE port could be connected to a Netonix switch with its PoE off. It outputs 48VDC on a non-standard pins 3,6 +48V and pins 1,2 Return.
What would happen if PoE in the switch was turned off, but some form of PoE was applied to the port externally?
On the 2-pair only ports, are there magnetics for PoE injection on all 4 pairs, and only 2 are used, or just on the 2 pairs that are used? If they are on all 4 pairs but only 4,5 and 7,8 are used, it seems to me the G2 could be connected safely.
On the 4-pair ports, I can't even speculate about how it may or may not work.
Thank you - Chris

Re: WS-6-MINI Magnetics and Undesired PoE In
On the V ports, center taps exist for the magnetics on non-POE pairs but are resistively and capacitively grounded, and are not otherwise terminated.
As far as what happens when external POE is applied- it's magnetically coupled, you shouldn't break anything on a 6-mini (as long as you don't put opposite polarities on a single pair) - this applies to both V and VH ports.
Short answer - I plugged the POE out of one of our VH ports into both ports 2 and 3 of a 6-mini - No smoke so far, it's been 15 minutes or so.

Re: WS-6-MINI Magnetics and Undesired PoE In
With the WS-6-MINI you can power it with UBNT/Netonix/MIMOSA POE bricks that devier power on all 4 pair as Port 1 of the WS-6-MINI uses bridge rectifier to correct polarity pin outs on pairs. IT WILL NOT CORRECT IMPROPER CRIMPS WHERE YOU HAVE POSITIVE AND NEGATIVE ON THE SAME PAIR - POOF
All MIMOSA radios can be powered by our switches as all MIMOSA radios use bridge rectifiers on their POE IN so ignore the Polarity PIN out with MINIOSa radios as well. But once again they will not correct an improperly crimped end that puts both polarity on a single pair.
Meaning White/Orange and Orange wires must have to have the same polarity applied to them
Meaning White/Green and Green wires must have to have the same polarity applied to them
Meaning White/Blue and Blue wires must have to have the same polarity applied to them
Meaning White/Brown and Brown wires must have to have the same polarity applied to them

Re: WS-6-MINI Magnetics and Undesired PoE In
@sirhc, I'm actually asking about running a PoE supply into a PoE out port on the Netonix. @Julian explained exactly what I was looking for.
How are the functioning center taps handled with PoE is turned off? Also resistively and capacitively grounded?
