A Troubleshooting
Diagnosing LED Indicators
System Self-Diagnostic Test Failure
If the Power LED indicates a failure of the system power-on-self-test (POST), you can
use a console connection to view the POST results. The POST results may indicate a
failed component or help troubleshoot the problem.
Note a POST failure normally indicates a serious hardware fault that cannot be
rectified or worked around. If you encounter a POST failure, you should contact
your dealer for assistance.
Power Problems
If the power indicator does not turn on when the power adapter is plugged in, you
may have a problem with the power outlet, power cord, or power adapter.
However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet. If you still cannot isolate
the problem, the power adapter may be defective.
