The system diagnostic programs are provided in ROM. These programs test the major components of your server. See "Diagnostic programs and error messages" on page 14. v Light path diagnostics Use light path diagnostics to diagnose system errors quickly. See "Light path diagnostics" on page 17 for more information. POST error logs When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test, or POST. If POST finishes without detecting any problems, a single beep sounds, and the first screen of your operating system or application program appears. If POST detects a problem, more than one beep sounds, and an error message appears on your screen. See "Beep symptoms" on page 74 and "POST error codes" on page 77 for more information. Notes: 1. If you have a power-on password or administrator password set, you must type the password and press Enter, when prompted, before POST will continue. 2. A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will not occur the next time you run the test. The POST error log contains the three most recent error codes and messages that the system generated during POST. The system-error log or base-board management controller (BMC) log contains all messages issued during POST and all system status messages from the service processor. You can view the contents of the system-error log and BMC log from the Configuration/Setup Utility program or from the diagnostic programs. Viewing error logs from the Configuration/Setup Utility program To view error logs from the Configuration/Setup Utility program, start the Configuration/Setup Utility program; then, select Error Logs from the main menu. See Chapter 2, "Configuring the server," on page 9 for more information. Viewing error logs from diagnostic programs To view error logs from diagnostic programs, complete the following steps: 1. Start the diagnostic programs. 2. Select Hardware Info from the top of the diagnostic programs screen. 3. Select System Error Log or BMC Log from the list that appears; then, follow the instructions on the screen. See "Starting the diagnostic programs" on page 15 for more information. ServerGuide error symptoms Look for the symptom in the left column of the chart. Probable solutions to the problem are in the right column. Chapter 3. Diagnostics 13

The
system
diagnostic
programs
are
provided
in
ROM.
These
programs
test
the
major
components
of
your
server.
See
“Diagnostic
programs
and
error
messages”
on
page
14.
v
Light
path
diagnostics
Use
light
path
diagnostics
to
diagnose
system
errors
quickly.
See
“Light
path
diagnostics”
on
page
17
for
more
information.
POST
error
logs
When
you
turn
on
the
server,
it
performs
a
series
of
tests
to
check
the
operation
of
server
components
and
some
of
the
options
installed
in
the
server.
This
series
of
tests
is
called
the
power-on
self-test,
or
POST.
If
POST
finishes
without
detecting
any
problems,
a
single
beep
sounds,
and
the
first
screen
of
your
operating
system
or
application
program
appears.
If
POST
detects
a
problem,
more
than
one
beep
sounds,
and
an
error
message
appears
on
your
screen.
See
“Beep
symptoms”
on
page
74
and
“POST
error
codes”
on
page
77
for
more
information.
Notes:
1.
If
you
have
a
power-on
password
or
administrator
password
set,
you
must
type
the
password
and
press
Enter,
when
prompted,
before
POST
will
continue.
2.
A
single
problem
might
cause
several
error
messages.
When
this
occurs,
work
to
correct
the
cause
of
the
first
error
message.
After
you
correct
the
cause
of
the
first
error
message,
the
other
error
messages
usually
will
not
occur
the
next
time
you
run
the
test.
The
POST
error
log
contains
the
three
most
recent
error
codes
and
messages
that
the
system
generated
during
POST.
The
system-error
log
or
base-board
management
controller
(BMC)
log
contains
all
messages
issued
during
POST
and
all
system
status
messages
from
the
service
processor.
You
can
view
the
contents
of
the
system-error
log
and
BMC
log
from
the
Configuration/Setup
Utility
program
or
from
the
diagnostic
programs.
Viewing
error
logs
from
the
Configuration/Setup
Utility
program
To
view
error
logs
from
the
Configuration/Setup
Utility
program,
start
the
Configuration/Setup
Utility
program;
then,
select
