EPUB_PRC_COOLING_SYSTEM_ERR isolation procedure

One or more processor sensors detected an over temperature condition.
About this task
To resolve the over temperature condition, complete the following steps:
Procedure
1. Is the room temperature less than 35°C (95°F)?
If
No:
Yes:
2. Are the system front and rear doors free of obstructions?
If
No:
Yes:
3. Perform the service action that is indicated for any system event logs that are related to fans and
occurred prior to the problem that you are working on. Go to "Identifying a service action by using
system event logs" on page 18. This ends the procedure.
Then
Bring the room temperature to within the allowable operating range. This ends the
procedure.
Continue with the next step.
Then
The system must be free of obstructions for proper air flow. Remove any obstructions.
This ends the procedure.
Continue with the next step.
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
"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,
replace system processor CPU 1. If replacing
system processor CPU 1 does not resolve the
problem, replace system processor CPU 2. Go to
"9006-22P locations" on page 91 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
