mAP-2n POE to mAP-2n when powered from USB?
Hi Folks, Getting ready for a camping trip this weekend, and I'm not sure if I'm losing my mind, or just being forgetful, but I can't seem to get one mAP-2n to power the other over PoE, when it is powered from USB? Works fine when I power the first one from 12V DC, but not when I power it from USB. Is that standard? I'm *SURE* the last time I used this little setup (Granted, it was back in April), that I was powering it all from USB.. The PoE out light comes up on the first device when powered from USB, but the second one never powers on. The second ONLY powers on when I power the first from DC. If that's the way it has to be, that's cool, I'll just shove them under the seat of the bike, hard wired into the battery, rather than in my tank bag powered from 20Ah LiPo like I was planning ;) -- Damien Gardner Jnr VK2TDG.

Hi Damien, That would be expected behaviour - USB power is just 5v and minimum PoE voltage is 9v :-j Cheers! Mike. thunder.

Ahhhhh, I figured there would be a DC-DC converter in there to give a constant 48v ;) All good, ended up making a powerpole->dc jack cable, and now they're running happily off the 130AH battery in the trailer. https://fbcdn-photos-c-a.akamaihd.net/hphotos-ak-xpa1/v/t1.0-0/s480x480/12011237_10153303680877763_6990662557605781348_n.jpg?oh=ad4b01803b6bc51fef5920576c043365&oe=56A12CB6&__gda__=1450222409_de63ee9dc7a9fe7683cc768ed53eb778 *grin* does your camper trailer run MPLS?
