The problem is the multi-adapter bridge hardware on a system bus.

Perform the following:

1. 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 Hardware Management Console (HMC)?
   • 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.

2. The failing component is the FRU containing the multi-adapter 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 exchange the FRU.

This ends procedure.
