Power and Cooling Problems

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.
