temperature error
The system temperature has exceeded a
threshold level.
1. Check to see if a blower on the
BladeCenter unit has failed. If it has,
replace the blower.
2. Make sure the room temperature is not too
high. (See “Features and specifications” on
page 4 for temperature information.)
3. Check the management module for
ThermTrip errors and replace
microprocessors as needed.
Processor x error The microprocessor has failed.
1. Make sure that the microprocessor
indicated by the lit LED is installed
correctly. (See “Installing an additional
microprocessor” on page 46 for installation
instructions).
2. Replace the microprocessor.
Processor
mismatch
The processors do not match. Make sure that all microprocessors have
the same cache size and type and the same
clock speed. Internal and external clock
frequencies must be identical; also see
“Error symptoms.”
BMC fault The BMC self-test has detected a failure
1. Reset and initialize the blade server and
I/O board.
2. Replace the I/O board.
NMI error A non-maskable interrupt has occurred.
1. Replace the blade server cover, reinsert
the blade server in the BladeCenter unit,
and then restart the blade server.
2. Check the system error log for information
about the error.
3. Replace the processor board and the I/O
board. See “Processor board” on page 72
and “I/O board” on page 74 for instructions.
Error symptoms
You can use the error symptom table to find solutions to problems that have definite
symptoms.
If you cannot find the problem in the error symptom charts, go to “Starting the
diagnostic programs” on page 26 to test the server.
If you have just added new software or a new option and your server is not
working, do the following before using the error symptom charts:
v Remove the software or device that you just added.
v
Run the diagnostic tests to determine if your server is running correctly.
v Reinstall the new software or new device.
In the following table, if the entry in the FRU/action column is a suggested action,
perform that action; if it is the name of a component, reseat the component and
replace it if necessary. The most likely cause of the symptom is listed first.
