Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 83)," 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 84)." 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 83)
• General diagnosis flowchart (on page 84)
• Server power-on problems flowchart (on page 86)
• POST problems flowchart (on page 89)
• OS boot problems flowchart (on page 90)
