Power Cord Not Plugged In
If the power supply cable is not plugged into the chassis power
connector, the system cannot boot up, even though chassis
front panel LEDs and the fan may be operational. Verify that the
power connections are good.
Processor Issues
Boot failure situations are also caused by the following:
Incompatible processor - ensure the selected processor model
is correct for your server board. If the processor is compatible,
try removing and reinstalling the processor to ensure it is
installed correctly.
Processor overheat-the system does not boot or shuts down
shortly after booting.
Ensure that the cooling fans are correctly installed and
running.
Ensure that the correct thermal interface material or the
thermal grease is applied to the processor.
Ensure that the power supply fan is running.
