Loose connections
Action:

have bent pins or damaged connectors.
• If a fixed cable tray is available for the server, be sure the cords and cables
connected to the server are correctly routed through the tray.
• Be sure each device is properly seated.
• 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.
Diagnostic steps
To effectively troubleshoot a problem, HP recommends that you start with the
first flowchart in this section, "Start diagnosis flowchart (on page 84
)," 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 86
)." 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 84
)
• General diagnosis flowchart (on page 86
)
• Power-on problems flowchart (on page 88
