Epub_Prc_Power_Error Isolation Procedure - IBM Power System 8335-GCA Manual

If Then
Yes: Continue with the next step.
No: Continue with step 5.
4. For each of the SELs that you identified in step 2 on page 102, determine the sensor name that is
associated with each SEL. Replace the following items, one at a time, until the problem is resolved:
Note: If your system is an 8335-GCA or 8335-GTA, go to "8335-GCA and 8335-GTA locations" on
page 111 to identify the physical location and removal and replacement procedure. If your system is
an 8335-GTB, go to "8335-GTB locations" on page 121 to identify the physical location and removal
and replacement procedure.
v If the sensor name is CPU Func 1 or CPU Core Func x, where x is 1 - 12, replace system processor
CPU 1.
v If the sensor name is CPU Func 2 or CPU Core Func x, where x is 13 - 24, replace system processor
CPU 2.
v If the sensor name is Mem Buf Func 1, replace memory riser 1. If the sensor name is Mem Buf Func
2, replace memory riser 2. And so on.
Does the problem persist?
If Then
Yes: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
No: This ends the procedure.
5. The system is an 8348-21C. For each of the SELs that you identified in step 2 on page 102, are any of
the sensor names CPU Func or CPU Core Func x, where x is 1 - 12?
Note: Go to "8348-21C locations" on page 133 to identify the physical location and removal and
replacement procedure.
If Then
Yes: Replace the system processor. Then, continue with the next step.
No: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
6. Does the problem persist?
If Then
Yes: Replace the system backplane. If the replacement of the system backplane does not resolve
the problem, go to "Contacting IBM service and support" on page 110. This ends the
procedure.
No: This ends the procedure.

EPUB_PRC_POWER_ERROR isolation procedure

A power problem occurred.
Perform the service action indicated for any system event logs that are related to power and occurred
prior to the problem that you are working on. Go to "Identifying a service action by using system event
logs" on page 27. This ends the procedure.
