FSPSP55

An error has been detected on a bus between two FRUs. The endpoint FRUs have been called out. However, the source of the error could be the bus path between the FRUs.

Refer to System FRU locations for information on FRU and removal when performing FSPSP55.
Select the system that you are servicing and then perform the indicated FSPSP55 procedure.
