Troubleshooting Basics
When your system does not function properly (or as you expect it to operate), the first thing that you must
do is identify and isolate the problem. When you have accomplished this, you can effectively begin to
resolve the problem.
The first step is to isolate each system component and ensure that each component functions properly
when it is run independently. You may have to dismantle your system and put it back together piece by
piece to detect the problem. If you have additional units available, you may want to exchange them with
existing components in your system to help identify the source of the problem.
Determine if the problem is mechanical, electrical, or software-related. Can you repeat or re-create the
problem? Random events may appear to be related, but they are not necessarily contributing factors to
your problem. You may be experiencing more than one problem. You must isolate and solve one problem
at a time.
Log (document) all testing and problem isolation procedures. You may need to review and consult these
notes later. This will also prevent you from duplicating your testing efforts.
Once you isolate the problem, refer to the problem solutions contained in this chapter. If the problem
persists, contact your local technical support resource (see

below).
