Is this a CPE or tower application? If you are looking for separate DC power supply to feed a POE injector, why are you even messing with POE, when the RB4011 has a DC input? Which BTW can accept 48V if this is a tower application.

I’m interested in powering mikrotik RB4011 so I guess a 1A might cover it, but like to be able to give more power with 24v.

We're doing that for Ubnt/MT radios using 4$ 100mbit offbrand injectors and it's nice way to have something small and DC, with some redundancy, for cheap.

Also not sure why you want a separate wall wart and a round DC power plug rather than injector and power supply in one with an AC cord. There’s also the question of whether you’re looking for passive or 802.3af with signature detection and a status light. But you’d think between Tycon and POE Texas you could find whatever you want.

Why do the manufacturer solutions not work? For PS, do you need plastic-case "consumer" PSU or is a semi-open-frame OK?

Also looking for good PS too, 24v around 1.8A would be nice, again with the round DC male end on about 6’ cord from a wall wart is fine. For some reason can’t seem to find a good vendor of either of those items, that are known good over time and decent price. -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
