EPUB_PRC_PROC_XYZ_BUS isolation procedure

A diagnostic function detected an internal processor interface problem.
About this task
Use the following table to determine the service action:
54 Power Systems: Problem analysis, system parts, and locations for the 5104-22C, 9006-12P, 9006-22C, and
9006-22P
Service action
Replace the system backplane. If replacing the
system backplane does not resolve the problem,
replace system processor CPU 1. If replacing
system processor CPU 1 does not resolve the
problem, replace system processor CPU 2. Go to
"5104-22C or 9006-22C locations" on page 63 to
identify the physical location and removal and
replacement procedure.
If replacing the system backplane and both system
processors does not resolve the problem, go to
"Contacting IBM service and support" on page
61. This ends the procedure.
Replace the system backplane. If replacing the
system backplane does not resolve the problem,
replace system processor CPU 1. If replacing
system processor CPU 1 does not resolve the
problem, replace system processor CPU 2. Go to
"9006-12P locations" on page 75 to identify the
physical location and removal and replacement
procedure.
If replacing the system backplane and both system
processors does not resolve the problem, go to
"Contacting IBM service and support" on page
61. This ends the procedure.
Replace the system backplane. If replacing the
system backplane does not resolve the problem,

physical location and removal and replacement
procedure.
If replacing the system backplane and both system
processors does not resolve the problem, go to
