Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in
this section,
“Start diagnosis flowchart” (page 77) and follow the appropriate diagnostic path. If
the other flowcharts do not provide a troubleshooting solution, follow the diagnostic steps in
“General diagnosis flowchart” (page 77) . 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” (page 77)
• “General diagnosis flowchart” (page 77)
• “Server power-on problems flowchart” (page 79)
• “POST problems flowchart” (page 81)
• “OS boot problems flowchart” (page 82)
• “Server fault indications flowchart” (page 84)
