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 locate and correct a problem by using the information in this chapter, see Appendix A, "Getting help and technical assistance," on page 55, 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 also appear during startup 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 charts These charts list problem symptoms and actions to correct the problems. See "Troubleshooting tables" on page 43 for more information. v Dynamic System Analysis (DSA) Preboot diagnostic programs The DSA Preboot diagnostic programs are provided on the Dynamic System Analysis Preboot CD. These programs test the major components of the server and collect and analyze system information. See the Problem Determination and Service Guide on the IBM System x Documentation CD 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 detecting any errors. Other beep codes See the Problem Determination and Service Guide on the IBM System x Documentation CD for information about other beep codes. © Copyright IBM Corp. 2007, 2008 35

correct
a
problem
by
using
the
information
in
this
chapter,
see
Appendix
A,
“Getting
help
and
technical
assistance,”
on
page
55,
the

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
also
appear
during
startup
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
charts
These
