That's a good point, I think I've also figured out I can't power anything BUT cambium 450i and 450m with the two cards I have. So I'll need a polarity agnostic card I believe.
I didn't think long enough but I think you're right, each port can be a seperate power supply. So 450m on each power supply then on the third one could carry a mimosa and the 820 On Wed, Dec 12, 2018 at 4:16 PM Mathew Howard <[email protected]> wrote: > I imagine it would probably be fine, since that's max load, and not what > it's typically going to be using, but 120 watts on a 120 watt power supply > is a bit closer than I'd want things to be. > > I assume your using a rack injector, which if I remember correctly, lets > you use any power input on any of the ports (regardless of what card > they're on), so why not use all three power supplies? > > On Wed, Dec 12, 2018 at 2:24 PM Ryan Ray <[email protected]> wrote: > >> Would like to tag on this, I've sent this off to packeflux support as >> well but maybe the crowd can tell me if this is good. >> >> I would like to power the following. >> >> >> >> 1 – PMP450i (5ghz) >> >> 2 – PMP450m (5ghz) >> >> 1 – PTP820S (18ghz) >> >> 1 – Mimosa B24 (24ghz) >> >> >> >> >> I’ve got two “Cambium Sync for 450i / 450m” boards.
