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 power supply unit.
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 power supply unit 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.
