We switched 2 months ago from geo stationary VSAT to inclined orbit. We have Vertex 4.8m to IS-603. It worked flawlessly for 2 months and then 3 times in last 8 days at 0230 GMT the link dropped. It was always the tracking. The screen on Antennae controller looks as if it is in manual mode, but the auto light was lit.
Does anyone have experience where we should be looking? I doubt it is power as it is on UPS running off batteries . Other servers on same UPS had no issues. Unfortunately i don't have exact what was on screen.
