Power and Cooling Problems
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. If you still cannot isolate the problem, the internal power supply
may be defective.
Installation
Verify that all system components have been properly installed. If one or
more components appear to be malfunctioning (such as the power cord or
network cabling), test them in an alternate environment where you are sure
that all the other components are functioning properly.
