Power Light Does Not Light
Check the following:

Is the system operating normally? If so, the power LED might be defective or the
cable from the control panel to the server board might be loose.
•
Have you securely plugged the server AC power cord into the power supply?
•
Some ATX power supplies have a power switch on the back of the power supply,
next to the fan. If your system has one, is it turned on?
•
Remove all add-in cards and see if the system boots. If successful, add the cards
back in one at a time with a reboot between each addition.

Make sure the memory DIMMs were populated according to the system
requirements.
