Troubleshooting flowcharts To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section, "Start diagnosis flowchart (on page 55)," 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 55)." 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 55) • General diagnosis flowchart (on page 55) • Server power-on problems flowchart ("Power-on problems flowchart" on page 57) • POST problems flowchart (on page 59) Troubleshooting 54
