Epub_Prc_Lvl_Support Isolation Procedure - IBM Power System 8335-GCA Manual

If Then
Yes: Continue with the next step.
No: Go to "Contacting IBM service and support" on page 110. This ends the procedure.
3. Is your system an 8335-GCA, 8335-GTA, or 8335-GTB?
If Then
Yes: Continue with the next step.
No: Go to step 5.
4. For each of the SELs that you identified in step 2 on page 98, 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 the 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 the
removal and replacement procedure.
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.
v If the sensor name is DIMM Func 1, replace DIMM 1. If the sensor name is DIMM Func 2, replace
DIMM 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 98, determine
the sensor name that is associated with each SEL. Replace the following items, one at a time, until the
problem is resolved:
Note: Go to "8348-21C locations" on page 133 to identify the physical location and the removal and
replacement procedure.
v If the sensor name is Membuf Func x, replace the system backplane.
v If the sensor name is DIMM Func 0, replace DIMM 0. If the sensor name is DIMM Func 1, replace
DIMM 1. And so on.
Does the problem persist?
If Then
If you have not already done so, replace the system backplane. If the replacement of the
Yes:
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.
