■ T est and diagnose hardware functionality
■ Locate hardware failures
■ I solate hardware and software faults
The diagnostics tests included with your system can help you eliminate the
hardware as a potential cause when you experience a server malfunction or when
debugging problems. For information about installing the diagnostics tests by means
