Troubleshooting 91
• If a device has latches, be sure they are completely closed and locked.
• Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
• If problems continue to occur, remove and reinstall each device, checking the connectors and sockets
for bent pins or other damage.

Troubleshooting flowcharts
To effectively troubleshoot a problem, HP recommends that you start with the first flowchart in this section,
"Start diagnosis flowchart (on page 91)," 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 92)." 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 91)
• General diagnosis flowchart (on page 92)
• Server power-on problems flowchart (on page 94)
• POST problems flowchart (on page 97)
• OS boot problems flowchart (on page 98)
