AC450 RMC HALT WITH OB ERROR
We are facing some AC450 faults for one of our customers, where controllers are going to 0B Fault intermittently.
It is a 4 CPU 14 slot rack, running with AC450 RMC.
Attached are 2 halt codes from 2 CPUS, taking during the fault, along with the system messages from all 4 cpus.
Can you help us giving some insights on the root cause please.
Matter a bit urgent, as it has already come 5-6 times in different CPUs. We have taken some corrective actions, however the root cause is yet to be determined.
Answers
Out of office, unable to verify but 0B could be PROM Checksum Error.
=> replace memory/CPU board
A post mortem analyze should tell which address (=memory module) where the corruption was found.
Please contact regional ABB service for assistance with analyze & spare parts.
