Diagnostic tools overview Diagnostic tools overview Server problems can be caused by the hardware, the software, or a user error. An example of a user error is pressing the wrong key on the keyboard. You can check the hardware by using the diagnostic test programs and the information in this chapter. Notes: 1. Some hardware and software errors are caused by configuration conflicts. For information on handling these situations, see "Resolving configuration conflicts" on page 57. 2. When running the diagnostic test programs, a single problem can cause several error messages to occur. When this happens, work to correct the cause of the first error message. After the cause is corrected, the other error messages probably will not occur the next time that you run the tests. If the hardware is OK and you have not made an error, you might have a software problem. If you suspect that you have a software problem, refer to the information that comes with that software package. The following tools are available to help identify and resolve hardware-related problems: Diagnostic test programs Power-on self-test (POST) POST beep codes Error messages Troubleshooting charts Option Diskettes Descriptions of these tools follow. 158 Netfinity 3000 User's Handbook
