Chapter 6. Solving problems
Server problems can be caused by hardware, software, or a user error. An
example of a user error is pressing the wrong key on the keyboard. You can check
server hardware by using the diagnostic programs and other information in this
chapter.
Diagnostic tools overview
The following tools are available to help identify and resolve hardware-related
problems:
EEPROM-based diagnostics
Power-on self-test (POST)
POST beep codes
Error messages
Troubleshooting charts
System error log
Option diskettes
Diagnostic programs
The Diagnostics Utility program contains several server diagnostic programs.
These diagnostic programs are stored on electrically erasable programmable
read-only memory (EEPROM). These programs are the primary method of testing
the major components of your server and some external devices.
Also, if you cannot determine whether a problem is caused by the hardware or by
the software, you can run the diagnostic programs to confirm that the hardware is
working properly.
Note:
When you run the diagnostic programs, a single problem might cause
several error messages. When this occurs, work to correct the cause of the
first error message. After the cause of the first error message is corrected,
the other error messages might not occur the next time that you run the
test.
