If we stop this CPU and again restart it then it will show REDF only for some time(2-3 hours), after that it will flash all led again. What should be the problem, and how can we troubleshoot it??? During diagnostic we found following messege, Defective: memory test error in internal memory No relevance for user(Z1):0040 Sir please help us.
