We are building a new site with ePMP2000 APs. Cable run is 175Ft, shelter to radio on tower. We have tried Cambium's 33A surge suppressors at top and bottom, Transector ALPU-Fit (what we usually use with ePMP 1000), and no surge. All cables have been throughly tested with a Fluke meter to indicate that all 8 wires + shield are intact.
What we are seeing is that the switch will show the port bounce about 10 times at 1gig before settling in at 100M-F. One of the 4 radios will bounce about 10 times 100M-F, then stay or drop to 10M-F.
If we remove the surge protectors, all 4 radios will link at 1gig.
The only thing that I can think of is a ground plane difference, but it's an FM site, with copper strap from the tower coming in to where we ground our cabinet and surges at.
Anybody have thoughts?
