•

Be sure all cables are properly aligned and securely connected for all external and internal

components.

• Remove and check all data and power cables for damage. Be sure no cables 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 66)," 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 67)." 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 66)

• General diagnosis flowchart (on page 67)

• Power-on problems flowchart ("Server blade power-on problems flowchart" on page 69)

• POST problems flowchart (on page 71)

• OS boot problems flowchart (on page 73)

• Server fault indications flowchart (on page 75)

The number contained in parentheses in the flowchart boxes corresponds to a table with references to

other detailed documents or troubleshooting instructions.
