Table 25. EPUB_PRC_TOD_CLOCK_ERR 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_COOLING_SYSTEM_ERR isolation procedure
One or more processor sensors detected an over temperature condition.
To resolve the over temperature condition, complete the following steps:
1.
Is the room temperature less than 35°C (95°F)?
If
Then
No:
Bring the room temperature to within the allowable operating range. This ends the
procedure.
Yes:
Continue with the next step.
2.
Are the system front and rear doors free of obstructions?
If
Then
No:
The system must be free of obstructions for proper air flow. Remove any obstructions. This
ends the procedure.
Yes:
Continue with the next step.
3.
Perform the service action 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 21. This ends the procedure.
