[AFMUG] EPMP1000 Heater POE Polarity

[Nate Burke]

I've been running some tests with Cold startup of EPMP1000 w/ sync 
Radios.  Does the Internal heater only function with 4/5-  7/8+?  A cold 
radio (18F) radio will power on but seems stuck in a reboot loop with 
4/5+  7/8-  The same radio powered on and booted within 2 minutes or so 
with 4/5- 7/8+

Power draw with 4/5+ 7/8- was around 4w, and would randomly spike to 
around 15w The power light would stay on, but sync and ethernet lights 
would go on and off, like it was continually rebooting.

Power draw with 4/5- 7/8+ was a solid 15w for about 2 minutes with only 
the power light on, then 4w once booted.

I just presumed that since it would power on with both polarities, the 
heater would work with both polarities as well.  It's looking like that 
might not be the case.
