I have got an hAP ac (RB962UiGS‑5HacT2HnT), that used to be connected to a Wifi ("Max") WAN. I was using ether5 to power the WAN antenna with PoE-out from the hAP.
I am now using Starlink (local offer for WifiMax has been dropped and FTH is not ready yet ).
Starlink antenna comes with a Starlink router, that I won't use, and a power supply (UTP‑253L) with two cables that, besides data, deliver 57V 17,5A LPS power.
For now, I plugged the first cable to the dish, and the "router" cable into the ether5 (PeO-out capable) of the hAP.
So :
can I plug this cable into the ether1 port (PeO-in capable) without risking to destroy my device ?
will it power the hAP ?
can I plug it into ether2-4 (non PoE ports) without destoying my device ?
Is any adapter necessary / possible ?
is PoE-out related to PeO-in in any way, or are these two different functions ?
You shouldn't hook the power supply directly to any port of the hAP AC device.
AFAIK the starlink power supply is "always on" and uses all pairs.
Maybe - just maybe - the ether1 port of the hAP can bear the "all pairs" voltage, but what if it doesn't. and you fry the device? (any other port won't do for sure)
Starlink has an "ethernet adapter", the exact model depends on the generation, but you can use any of the so-called "dishy" adapters, basically you need an adapter that strips the power from the cable.
Seems UTP‑253L brick belong to gen3 rev4. I used gen2 and that was PoE++ (IEEE 802.3bt) with different pins kind of starlink proprietary probably this one is same (just assumption). Since these lines carry voltage no possibility to use anywhere except starlink router unless open brick and cut powerlines. Use starlink router and take data from router from second port to distribute data over hap.
I checked and the UTP‑253L is the latest version, with it there is no need of an adapter.
One of the two ports carries the 57V (towards the antenna) while the other has what is seemingly a sort of active PoE that can recognize the Starlink router and only provides power in this case, so can be safely be connected to any device (and on any port).
Also notice I initially plugged this cable to ether5 (PoE-out) without any further thinking, and nothing broke (in fact everything worked, Starlink replaced the former Wifi WAN without problem). So I guess this "custom active PoE" works. I won't try ether1 though, seems too risky !
If the reverse engineering in the page linked to is accurate, it seems like very thorough as each pair is checked twice, for 3.2k and short.
The way the "probes" are made seems conservative enough (I know that using conservative in something even loosely related to Mr. Elon Musk is in itself a gamble ), no way that something can be powered by mistake, still I wouldn't want something continuously probing a port that has circuitry that is designed for different probes , in this the "normal" ports seem to me like a much better choice.
Switched from ether5 to ether2 for the starlink cable, and everything went fine (and I could use ether5 PoE-out to power my other device). So for the record, these Starlink cables are harmless for at least PoE-out and no PoE ports. I didn't try ether1 (PoE-in) port...
