Lit blade-error LED Cause Board The system temperature has exceeded a temperature error threshold level. Processor x error The microprocessor has failed. Processor mismatch The processors do not match. BMC fault NMI error The BMC self-test has detected a failure A non-maskable interrupt has occurred. Action 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. 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. 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." 1. Reset and initialize the blade server and I/O board. 2. Replace the I/O board. 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. Chapter 6. Symptom-to-FRU index 87

the
system
error
log
for
information
about
the

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.
