Power and Cooling Problems

If the Power LED does not turn on when the power cord is
plugged in, you may have a problem with the power outlet or
power cord as explained in the troubleshooting chart. 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 side of the unit are unobstructed
and running prior to shutdown. If you still cannot isolate the
problem, then the internal power supply may be defective. In this
case, contact your SMC dealer or reseller for assistance.
