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 the problem using the information in this chapter, see Appendix A, "Getting help and technical assistance," on page 93, the Problem Determination and Service Guide on the IBM System x3400 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 x3400 Documentation CD for more information. v ServerGuide problems This chart lists problem symptoms and steps to correct problems that occur when you are using the ServerGuide Setup and Installation CD. For more information, see "ServerGuide problems" on page 79. v Troubleshooting tables These tables list problem symptoms and steps to correct the problems. See "Troubleshooting tables" on page 79 for more information. v Diagnostic programs and error messages The diagnostic programs are the primary method of testing the major components of the server. These programs are on the IBM Enhanced Diagnostics CD that comes with the server. See the Problem Determination and Service Guide on the IBM System x3400 Documentation CD for more information. v System-board error LEDs An LED on the system board might be lit to help isolate an error that is indicated by the system-error LED on the front of the server. For more information, see "System-board LEDs" on page 91. POST beep codes POST emits one beep to signal a 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 x3400 Documentation CD for more information about the POST beep codes. One beep POST was completed successfully without finding any errors. © Copyright IBM Corp. 2008 67

lit
to
help
isolate
an
error
that
is
indicated
by
the
system-error
LED
on
the
front
of
the
server.
For
