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, Type 7377 server,” on page 125 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.
Message Severity Description Action
A software NMI has occurred
on system %1.
(%1 =
CIM_ComputerSystem.
ElementName)
Error A software NMI has occurred.
1. Check the device driver.
2. Reinstall the device driver.
A Uncorrectable Bus Error
has occurred on system %1.
(%1 =
CIM_ComputerSystem.
ElementName)
Error A bus uncorrectable error has
occurred.
(Sensor = Critical Int CPU)
1. Check the system-event log.
2. Check the microprocessor error
LEDs.
3. Remove the failing
microprocessor from the system
board.
4. Check for a UEFI 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.
5. Make sure that the two
microprocessors are matching
(see “Installing a
microprocessor and heat sink”
on page 223 for information
about microprocessor
requirements).
6. (Trained service technician only)
Replace the system board.
Note: Make sure the technician
refreshes the VPD.
An Over-Temperature
Condition has been detected
on the Processor CPU
n Status.
(n = microprocessor number)
Error An overtemperature condition has
occurred for microprocessor n.
(n = microprocessor number)
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.
