Hi,
I have 2 ptp650 on same pole. This pole its on the top of a mountain, so there are zero radio interferences. Because there are the only device on this pole, I have connected directly the 2 PIDU with a 30 cm utp cat6 patch cable.
This is the configuration:
PTP650-----LPU-----Cambium Cable (3 meters)------LPU------Cambium Cable (1 meter)------PIDU----Patch utp cat6 (30 cm)----PIDU-----Cambium Cable (3 meters)------LPU-----PTP650
The LPU model is: C000065L007A
Cambium Cable: WB3175 (REEL OUTDOOR COPPER CLAD CAT5)
Problem: in this configuration, the 2 "main PSU port speed" run at 100 Mbps Full Duplex.
I have substituted all devices (cable, connectors, PIDU, LPU, ptp650) but th eproblem persist.
If I remove the 2 (lower) LPU the port speed became 1000 Mbps Full duplex.
Because in this place there are a lot lightning and i must go to gigabit, I must resolve this problem. Any suggestion?
I see the same problem in differents tower, but right now I thinked that its caused by FM 300 mhz interferece. This situation show me that probably the LPU interfer with gigabit ethernet. How its possible?
Thanks
Pierre
