Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 61 )," and follow the appropriate diagnostic path. If the other flowcharts
do not provide a troubleshooting solution, follow the diagnostic steps in "General diagnosis flowchart (on
page 62 )." The General diagnosis flowchart is a generic troubleshooting process to be used when the
problem is not server-specific or is not easily categorized into the other flowcharts.
The available flowcharts include:
• Start diagnosis flowchart (on page 61 )
• General diagnosis flowchart (on page 62 )
• Server power-on problems flowchart (" Power-on problems flowchart " on page 64 )
• POST problems flowchart (on page 66 )
• OS boot problems flowchart (on page 68 )
• Server fault indications flowchart (on page 69 )
