8. Replace the components listed in step 7 one at a time, in the order
shown,
restarting the server each time.
9. If the DIMM was disabled, run the Setup utility and enable the
DIMM. See Chapter 6, “Configuration information and instructions,”.
3.5.9 Microprocessor problems
Table 3-10
Microprocessor problems
Follow the suggested actions in the order in which they are listed in the
Action column until the problem is solved.
See Chapter 4, “Parts listing, ” to determine which components are customer
replaceable units (CRU) and which components are field replaceable units
(FRU).
If an action step is preceded by “(Trained service technician only),” that step
must be performed only by a trained service technician.
Symptom
Action
The server does not
function
after
replacing
the
primary
microprocessor or
the
primary
microprocessor
error LED is lit.
1. Correct any errors that are indicated by the light path diagnostics
LEDs (see“Light path diagnostics”).
2. Make sure that the server supports all the microprocessors and that
the
microprocessors match in speed and cache size.
3. Reseat the following components:
a. Microprocessor 1 (see “Removing a microprocessor and heat
sink”)
b.(Trained service technician only) Microprocessor board (see
“Removing the microprocessor-board assembly” and “Replacing the
microprocessor-board assembly”)
4. (Trained service technician only) If there is no indication of which
microprocessor has failed, isolate the error by testing with one
microprocessor at a time.
5. Replace the following components one at a time, in the order shown,
restarting the server each time:
a. (Trained service technician only) Microprocessor 1
b. (Trained service technician only) Microprocessor board
6. (Trained service technician only) If multiple error codes or light path
diagnostics LEDs indicate a microprocessor error, reverse the locations
of two microprocessors to determine whether the error is associated
with a microprocessor or with a microprocessor socket.
(Trained service technician only) If the error is associated with a
microprocessor, replace the microprocessor.
(Trained service technician only) If the error is associated with a
microprocessor socket, replace the microprocessor board.
