Chapter 5. Solving problems This chapter provides basic troubleshooting information to help you solve some common problems that might occur while you are setting up the server. If you cannot diagnose and correct problems using the information in this chapter, see Appendix A, "Getting help and technical assistance," on page 77, the Problem Determination and Service Guide on the IBM System x Documentation CD, and the "Server Support" flowchart in the front of this document. Diagnostic tools overview The following tools are available to help you diagnose and solve hardware-related problems: v POST beep codes The power-on self-test beep codes indicate the detection of a problem. - One beep indicates successful completion of POST, with no errors. - More than one beep indicates that POST detected a problem. Error messages are displayed also if POST detects a hardware-configuration problem. See "POST beep codes" and the Problem Determination and Service Guide on the IBM System x Documentation CD for more information. v Troubleshooting tables These tables list problem symptoms and actions to correct the problems. See "Troubleshooting tables" on page 61 for more information. v Diagnostic programs and error messages The system diagnostic programs are provided in ROM. These programs test the major components of the server. See the Problem Determination and Service Guide on the IBM System x Documentation CD for more information. v Light path diagnostics Use light path diagnostics to diagnose system errors quickly. See "Light path diagnostics" on page 73 for more information. POST beep codes POST emits one beep to signal successful completion. If POST detects a problem during startup, other beep codes might occur. Use the following beep code descriptions to help diagnose and solve problems that are detected during startup. Note: See the Problem Determination and Service Guide on the IBM System x Documentation CD for more information about the POST beep codes. One beep POST was completed successfully without finding any errors. Repeating long beeps A memory error has occurred. Make sure that all DIMMs are correctly installed. One long beep and two short beeps A video error has occurred, and the BIOS cannot initialize the monitor screen to display additional information. © Copyright IBM Corp. 2007 57

This
chapter
provides
basic
troubleshooting
information
to
help
you
solve
some
common
problems
that
might
occur
while
you
are
setting
up
the
server.
If
you
cannot
diagnose
and
correct
problems
using
the
information
in
this
chapter,
see
Appendix
A,
“Getting
help
and
technical
assistance,”
on
page
77,
the
Problem
Determination
and
Service
Guide
on
the
IBM
System
x
Documentation
CD,
and
the
“Server
Support”
flowchart
in
the
front
of
this
document.
Diagnostic
tools
overview
The
following
tools
are
available
to
help
you
diagnose
and
solve
hardware-related
problems:
v
POST
beep
codes
The
power-on
self-test
beep
codes
indicate
the
detection
of
a
problem.
One
beep
indicates
successful
completion
of
POST,
with
no
errors.
More
than
one
beep
indicates
that
POST
detected
a
problem.
Error
messages
are
displayed
also
if
POST
detects
a
hardware-configuration
problem.
See
“POST
beep
codes”
and
the
Problem
Determination
and
Service
Guide
on
the
IBM
System
x
Documentation
CD
for
more
information.
v
Troubleshooting
tables
These
tables

v
Diagnostic
programs
and
error
messages
The
system
diagnostic
programs

POST
beep
codes
POST

successful
completion.
If
POST
detects
a
problem
during
startup,
other
beep
codes
might
occur.
Use
the
following
beep
code
descriptions
to
help
diagnose
and
solve
problems
that
are
detected
during
startup.
Note:
See
the
Problem
Determination
and
Service
Guide
on
the
IBM
System
x
Documentation
CD
for
more
information
about
the

beep
codes.
One
beep
POST
was
completed
successfully
without
finding
any
errors.
Repeating
long
beeps
A
memory
error
has
occurred.
Make
sure
that
all
DIMMs
are
correctly
installed.
One
long
beep
and
two
