Power-on problems

If the system does not boot after you have applied power, check the 
following factors that might have caused the boot failure.

The external power cord may be loosely connected.

Check the power cord connection from the power source to the 
power supply module AC input connector on the rear panel. Make 
sure that the power cord is properly connected to the power 
source and to the AC input connector. 

No power comes from the grounded power outlet.

Have an electrician check your power outlet.

Loose or improperly connected internal power cables.

Check the internal cable connections. If you are not confident to 
perform this step, ask a qualified technician to assist you.

Warning! Make sure all power cords are disconnected from 
the electrical outlet before performing this task. 

Note: If you have gone through the preceding actions and the 
system still fails to boot, ask your dealer or a qualified technician 
for assistance.
