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 as explained in the
previous section. 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 fan on the
right side of the unit (F5D5141-24) is 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 (e.g., the power cord or
network cabling) appear to be malfunctioning, test them in an
alternate environment where you are sure that all the other
components are functioning properly.
