4 2.4 epmp access points with about 20 feet of cable on top of a firetower. they are all gps.
did i not just read somewhere here the gps 2.4 epmp access points were 48v? ----- Original Message ----- From: Josh Luthman To: CBB - Jay Fuller Cc: Josh Baird ; AFMUG Sent: Thursday, June 21, 2018 2:47 PM Subject: Re: [AFMUG] ePMP voltages again - specifically 2ghz What exactly are you powering? Epmp comes with a 24v poe and if you've got say 100 feetish? you're at 23 volts..that's minimum boot for warm weather. If it loses power in cold (20F?) it won't come back on until it warms up.

You could always throw a small PoE switch (Netonix or whatever) that can do both 24V and 48V. I realize this may not be the most convenient thing for you to do.. I'm just saying - a lot of our problems with ePMP went away when we switched to 48V.

The 5 GHz is just fine but the 2 GHz is saying current too low. Both ports are getting 23 volts and the cables are <10 feet (from the Powerbox Pro). Does anyone know if the 2ghz requires more voltage possibly? Spec sheet does say 23 volts min but it's weird one powers (5 ghz) and the other doesn't.
