Diagnostic flowcharts Troubleshooting flowcharts To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section, "Start diagnosis flowchart (on page 24)," 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 25)." 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 24) • General diagnosis flowchart (on page 25) • Power-on problems o Server power-on problems flowchart (on page 26) o p-Class server blade power-on problems flowchart (on page 28) o c-Class server blade power-on problems flowchart (on page 28) • POST problems flowchart (on page 29) o Server and p-Class server blade POST problems flowchart (on page 30) o c-Class server blade POST problems flowchart • Operating system boot problems flowchart • Server fault indications flowchart (on page 32) o Server and p-Class server blade fault indications flowchart o c-Class server blade fault indications flowchart Troubleshooting flowchart reference websites Each flowchart contains references to external websites.
