[AFMUG] ePMP sync AP hardware variants?

[Kurt Fankhauser]

Are there different hardware versions of the ePMP AP with sync floating
around out there? I received a 5ghz ePMP AP w/ Sync (according to the box)
from attending the EPMP road show a year ago. This unit did not have a sma
connector under the cover and looked like a normal connectorized SM with 2
RJ-45 ports. Although the box stated on the outside it was a SYNC ap. Is
this a unit that will only accept sync over power or what is this thing
exactly?
