Hello all, I am running into a very weird issue between our Nanobeam M5 400mm 25db feedhorn and a Mikrotik RB750UP. When I try to power up the M5 feedhorn with the POE out ports on the Tik, the feedhorn powers up the first time and stays online until I unplug it. When I plug it in a second time, it no longer powers up and doesn't even attempt to turn on. When I force the POE port on, it says short circuit and does not power up. If I plug in a Loco or M2 nanobeam feedhorn, they power up all day every day as many times as I can plug them in.
So to test further, I plug in a second and third M5 feedhorn and they all power up the first time only and when plugging in for a second time, nothing at all. I've tried 3 Tik's from different batches and they all do the same thing. M5 feedhorn has issues, locos and m2 feedhorns fine. The only thing I can think of is the M5 feedhorn support 1000 Mbps LAN speed but it has always been fine running on these RB750UP before without issue which is very weird. Also, the M5 feedhorns aren't fried when I do this as they power up just fine from a standard ubiquiti POE afterwards. They'll just never power up again from the 750UP. Any ideas? -- Darin Steffl Minnesota WiFi www.mnwifi.com 507-634-WiFi <http://www.facebook.com/minnesotawifi> Like us on Facebook <http://www.facebook.com/minnesotawifi>
