Dear All I am facing a strange issue with one of my RB433.
It foes down randomly, dont know the reason why, cheked and changed everything.....the wires, connectors, poe injector, power supply, still cant figure out the problem....even tried to upgrade system packages.. but the problem remains same.

It works very fine for few days or sometimes a month or so and then all of a sudden starts hanging, i cant connect to it on any of the interfaces and so finally has to reboot manually to start using it again.

Please can anyone throw some light on this issue..

Check the grounding of 433. Also check the system voltage when it starts to hang
