Did you change power supply? Are there high power cards on RB433AH? Use 24V, 1A power adapter, use max 2 high power and 1 normal power card (2xR52H, 1xR52).

Yes, i changed the PS. 3 RF boards freeze at the same time.
I thought Washington noise, but i usted spectrum analizer, and dont see nothing extrañe (i think).
I read about its a problem of r52n. Somebody know IT???
Ideas???
Regards!!
