Diagnosing RPS Indicators
Power and Cooling Problems
If the fan LED 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, and verify that the fans on 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
distributor for assistance.
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 RPS cable),
test them in an alternate environment where you are sure that all the other
components are functioning properly.
