v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 4, “Parts listing, System x3200 M3 Types 7327 and 7328,” on page 133 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
An SM BIOS Uncorrectable CPU
complex error for Processor CPU
nStatus has asserted.
(n = microprocessor number)
Error An SMBIOS uncorrectable
CPU complex error has
asserted.
1. Check for a server firmware
update.
Important: Some cluster
solutions require specific code
levels or coordinated code
updates. If the device is part
of a cluster solution, verify that
the latest level of code is
supported for the cluster
solution before you update the
code.
2. Make sure that the installed
microprocessor is compatible
with each other (see “Installing
a microprocessor and fan
sink” on page 211 for
information about
microprocessor requirements).
3. (Trained service technician
only) Reseat microprocessor
n.
4. (Trained service technician
only) Replace microprocessor
n.
(n = microprocessor number)
Sensor CPU nOverTemp has
transitioned to critical from a less
severe state.
(n = microprocessor number)
Error A sensor has changed to
Critical state from a less
severe state.
1. Make sure that the fans are
operating, that there are no
obstructions to the airflow, that
the air baffle is in place and
correctly installed, and that the
server cover is installed and
completely closed.
2. Make sure that the heat sink
for microprocessor n is
installed correctly.
3. (Trained service technician
only) Replace microprocessor
n .
