system error 902

[woonsteel]

All,
I just bought a spare "Motherboard" A20B-0008-0410 after replacing the spare to the original together with all the original "Daughter Boards, it doesn't seems to function. Then i put back the original "Motherboard" and system error 902 appeared on my Fanuc 6MB monitor. Previously my original "Motherboard" is in working condition but now both spare and original "Motherboards" becomes faulty, any suggestions?What is system error 902 stand for? Anything to do with the Rom board or can i do any resetting?

alarm 902 is a bubble board error. Either your mother board or your bubble board failed. Call me.
