Diagnosing Power Problems with the LED Indicators
The Power and RPU LED indicators work in combination to indicate power status as
follows.
Table A-2. Power/RPU LED Indicators
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 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, the
internal power supply may be defective.
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.
