Diagnostic error messages indicate that a problem exists. They are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel. Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears. Chapter 6, "Symptom-to-FRU index," on page 101 contains the error codes that might appear in the detailed test log and summary log when the diagnostic programs are run. The error code format is as follows: fff-ttt-iii-date-cc-text message where: fff is the three-digit function code that indicates the function being tested when the error occurred. For example, function code 089 is for the microprocessor. ttt is the three-digit failure code that indicates the exact test failure that was encountered. (These codes are for trained service personnel; see "Diagnostic error codes" on page 103). iii is the three-digit device ID. (These codes are for trained service personnel; see "Diagnostic error codes" on page 103). date is the date that the diagnostic test was run and the error recorded. cc is the check value that is used to verify the validity of the information. text message is the diagnostic message that indicates the reason for the problem.

Diagnostic
error
messages
indicate
that
a
problem
exists.
They
are
not
intended
to
be
used
to
identify
a
failing
part.
Troubleshooting
and
servicing
of
complex
problems
that
are
indicated
by
error
messages
should
be
performed
by
trained
service
personnel.
Sometimes
the
first
error
to
occur
causes
additional
errors.
In
this
case,
the
server
displays
more
than
one
error
message.
Always
follow
the
suggested
action
instructions
for
the
first
error
message
that
appears.
Chapter
6,
“Symptom-to-FRU
index,”
on
page
101
contains
the
error
codes
that
might
appear
in
the
detailed
test
log
and
summary
log
when
the
diagnostic
programs
are
run.
The
error
code
format
is
as
follows:
fff-ttt-iii-date-cc-text
message
where:
fff
is
the
three-digit
function
code
that
indicates
the
function
being
tested
when
the
error
occurred.
For
example,
function
code
089
is
for
the
microprocessor.
ttt
is
the
three-digit
failure
code
that
indicates
the
exact
test
failure
that
was
encountered.
(These
codes
are
for
trained
service
personnel;
see
“Diagnostic
error
codes”
on
page
103).
iii
is
the
three-digit
device
ID.
(These
codes
are
for
trained
service
personnel;
see
“Diagnostic
error
codes”
on
page
103).
date
is
the
date
that
the
diagnostic
test
was
run
and
the
error
recorded.
cc
is
the
check
value
that
is
used
to
verify
the
validity
of
the
information.
text
message
is
the
diagnostic
message
that
indicates
the
reason
for
the
problem.
