The problem is the multiadapter bridge hardware on a system bus.
Complete the following steps:
- Is the location information for this failing component available
in the problem view you are working with of the serviceable event
user interface of an operating system, service processor, or management console?
- No: Record the bus number value, BBBB, in word 7 of the reference code and continue with the next step.
- Yes: Use this location information and continue with the next step.
- The failing component is the FRU that contains the multiadapter bridge. Use the following table to identify the name of the FRU that is indicated by the location in the user interface you are working with, or by using the bus number you obtained previously in this procedure to replace the FRU.
