Table A-1. Troubleshooting Chart

Symptom

Action

outlet.

Fan LED is Flashing Red

as possible.

 

 

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.
