6.2 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 your 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 loss or surging at the power outlet, and verify that the fans on the
unit are unobstructed and running prior to shutdown.
6.3 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.
