POST error messages POST error messages can appear when a problem is detected during startup. For a complete list of POST messages, see "POST error codes" on page 90. Diagnostic programs and error messages The system diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major components of the server. The IBM Enhanced Diagnostics programs isolate problems from the server hardware and software. The programs run independently of the operating system and must be run either from a CD or diskette. If you want to run the diagnostic programs from a diskette, you must attach an external USB diskette drive to the server. Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing complex problems 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. Error codes that might be displayed are listed at "Diagnostic error codes" on page 80. 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 201 is for memory. ttt is the three-digit failure code for the exact test failure. (These codes are for trained service personnel.) iii is the three-digit device ID. (These codes are for trained service personnel.) date is the date that the diagnostic test was run and the error recorded. cc are the check digits that are used to verify the validity of the information. text message is the diagnostic message that indicates the reason for the problem. 20 326m Type 7969: Hardware Maintenance Manual and Troubleshooting Guide

POST
error
messages
POST
error
messages
can
appear
when
a
problem
is
detected
during
startup.
For
a
complete
list
of
POST
messages,
see
“POST
error
codes”
on
page
90.
Diagnostic
programs
and
error
messages
The
system
diagnostic
programs
are
stored
on
the
IBM
Enhanced
Diagnostics
CD.
These
programs
are
the
primary
method
of
testing
the
major
components
of
the
server.
The
IBM
Enhanced
Diagnostics
programs
isolate
problems
from
the
server
hardware
and
software.
The
programs
run
independently
of
the
operating
system
and
must
be
run
either
from
a
CD
or
diskette
.
If
you
want
to
run
the
diagnostic
programs
from
a
diskette,
you
must
attach
an
external
USB
diskette
drive
to
the
server.
Diagnostic
error
messages
indicate
that
a
problem
exists;
they
are
not
intended
to
be
used
to
identify
a
failing
part.
Troubleshooting
and
servicing
complex
problems
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.
Error
codes
that
might
be
displayed
are
listed
at
“Diagnostic
error
codes”
on
page
80.
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
201
is
for
memory.
ttt
is
the
three-digit
failure
code
for
the
exact
test
failure.
(These
codes
are
for
trained
service
personnel.)
iii
is
the
three-digit
device
ID.
(These
codes
are
for
trained
service
personnel.)
date
is
the
date
that
the
diagnostic
test
was
run
and
the
error
recorded.
cc
are
the
check
digits
that
are
used
to
verify
the
validity
of
the
information.
text
message
is
the
diagnostic
message
that
indicates
the
reason
for
the
problem.
