Power and Cooling Problems
If the power indicator does not turn on when the power cord is plugged in,
there may be a problem with the DC power circuit, 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 from the DC
source, and verify that the unit’s cooling fans are unobstructed and running
prior to shutdown. If the problem still cannot be isolated, the internal power
supply may be defective.
13.3 Embedded
Nodes
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 another environment where all the other
components are functioning properly
