Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 44)," 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 45)." 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 44)
• General diagnosis flowchart (on page 45)
• Server power-on problems flowchart ("Power-on problems flowchart" on page 47)
• POST problems flowchart (on page 49)
• OS boot problems flowchart (on page 51)
• Server fault indications flowchart (on page 52)
