v Check the operator information panel system-error LED; if it is flashing, check the light path diagnostics LEDs (see "Light path diagnostics" on page 101). v Check for the following correct responses: - A single beep. - Readable instructions on the main menu. DID YOU RECEIVE THE CORRECT RESPONSES? 005 No. Find the failure symptom in "Problem isolation tables"; if necessary, see "Solving undetermined problems" on page 156. 006 Yes. Run the diagnostic programs (see "Running the on-board diagnostic programs" on page 111). v If you receive an error, see "Diagnostic error codes" on page 112. v If the diagnostics programs were completed successfully and you still suspect a problem, see "Solving undetermined problems" on page 156. If the server does not turn on, see "Problem isolation tables." Important: If the server has a baseboard management controller, clear the BMC log and system-event log after you resolve all conditions. This will turn off the information LED and LOG LED, if all conditions are resolved. (Trained service technicians only) Checkpoint codes Checkpoint codes give the check that was taking place at the time the system stopped; they do not provide error codes or suggested replacement parts. The checkpoint display will indicate where the server has stopped without waiting for the video to initialize at each startup during problem isolation. There are two types of checkpoint codes: CPLD hardware checkpoint codes, and BIOS checkpoint codes. The BIOS checkpoint codes might change when the BIOS code is updated. The checkpoint display for the System x3850 is located on the I/O board. Checkpoint codes can be found at http://w3.pc.ibm.com/helpcenter/infotips/techinfo/ MIGR-58350.html. Problem isolation tables Use the problem isolation tables to find solutions to problems that have definite symptoms. If you cannot find the problem in the error symptom charts, go to "Running the on-board diagnostic programs" on page 111 to test the server. If you have just added new software or a new option and the server is not working, use the following procedures before using the problem isolation tables: 1. Check the light path diagnostics LEDs on the operator information panel (see "Light path diagnostics" on page 101). 2. Remove the software or device that you just added. 3. Run the diagnostic tests to determine whether the server is running correctly. 4. Reinstall the new software or new device. 88 IBM System x3850 Type 8864: Problem Determination and Service Guide

v
Check
the
operator
information
panel
system-error
LED;
if
it
is
flashing,
check
the
light
path
diagnostics
LEDs
(see
“Light
path
diagnostics”
on
page
101).
v
Check
for
the
following
correct
responses:
–
A
single
beep.
–
Readable
instructions
on
the
main
menu.
DID
YOU
RECEIVE
THE
CORRECT
RESPONSES?
±005²
No.
Find
the
failure
symptom
in
“Problem
isolation
tables”;
if
necessary,
see
“Solving
undetermined
problems”
on
page
156.
±006²
Yes.
Run
the
diagnostic
programs
(see
“Running
the
on-board
diagnostic
programs”
on
page
111).
v
If
you
receive
an
error,
see
“Diagnostic
error
codes”
on
page
112.
v
If
the
diagnostics
programs
were
completed
successfully
and
you
still
suspect
a
problem,
see
“Solving
undetermined
problems”
on
page
156.
If
the
server
does
not
turn
on,
see
“Problem
isolation
tables.”
Important:
If
the
server
has
a
baseboard
management
controller,
clear
the
BMC
log
and
system-event
log
after
you
resolve
all
conditions.
This
will
turn
off
the
information
LED
and
LOG
LED,
if
all
conditions
are
resolved.
(Trained
service
technicians

Checkpoint
codes
Checkpoint
codes
give
the
check
that
was
taking
place
at
the
time
the
system
stopped;
they
do
not
provide
error
codes
or
suggested
replacement
parts.
The
checkpoint
display
will
indicate
where
the
server
has
stopped
without
waiting
for
the
video
to
initialize
at
each
startup
during
problem
isolation.
There
are
two
types
of
checkpoint
codes:
CPLD
hardware
checkpoint
codes,
and
BIOS
checkpoint
codes.
The
BIOS
checkpoint
codes
might
change
when
the
BIOS
code
is
updated.
The
checkpoint
display
for
the
System
x3850
is
located
on
the
I/O
board.
Checkpoint
codes
can
be
found
at
MIGR-58350.html.
Problem
isolation
tables
Use
the
problem
isolation
tables
to
find
solutions
to
problems
that
have
definite
symptoms.
If
you
cannot
find
the
problem
in
the
error
symptom
charts,
go
to
“Running
the
on-board
diagnostic
programs”
on
page
111
to
test
the
server.
If
you
have
just
added
new
software
or
a
new
option
and
the
server
is
not
working,
use
the
following
procedures
before
using
the
problem
isolation
tables:
1.
Check
the
light
path
diagnostics
LEDs
on
the
operator
information
panel
(see
“Light
path
diagnostics”
on
page
101).
2.
Remove
the
software
or
device
that
you
just
added.
3.
Run
the
diagnostic
tests
to
determine
whether
the
server
is
running
correctly.
4.
Reinstall
the
new
software
or
new
device.
