The Power and RPU LEDs work in combination to indicate power status as follows.

If the power indicator does not turn on when the power cord is plugged in, you may 
have a problem with the power outlet, power cord, or internal power supply. 
However, if the unit powers off after running for a while, check for loose power 
connections, power losses or surges at the power outlet, and verify that the fans on 
the unit are unobstructed and running prior to shutdown. If you still cannot isolate the 
problem, then the internal power supply may be defective.
