Table 21. EPUB_PRC_FSI_PATH service actions (continued)
System
Service action
8001-22C or 8005-22N
Replace the following items, one at a time, in the order
that is shown until the problem is resolved:
1.
System processor CPU 1
2.
System processor CPU 2
3.
System backplane
Go to “8001-22C or 8005-22N locations” on page 87 to
identify the physical location and removal and
replacement procedure. If the replacement of the system
processors and the system backplane does not resolve the
problem, go to “Contacting IBM service and support” on
page 71. This ends the procedure.
EPUB_PRC_PROC_AB_BUS isolation procedure
A diagnostic function detected an external processor interface problem.
Use the following table to determine the service action:
Table 22. EPUB_PRC_PROC_AB_BUS service actions
System
Service action
8001-12C or 8005-12N
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 “8001-12C or 8005-12N locations” on page
73 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 71. This
ends the procedure.
8001-22C or 8005-22N
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 “8001-22C or 8005-22N locations” on page
87 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 71. This
ends the procedure.
EPUB_PRC_PROC_XYZ_BUS isolation procedure
A diagnostic function detected an internal processor interface problem.
Use the following table to determine the service action:
