3. Using the minimum confi guration for troubleshooting: Remove all unnecessary
components (starting with add-on cards fi rst), and use the minimum confi guration (but
with a CPU and a memory module installed) to identify the trouble areas. Refer to the
steps listed in Section A above for proper troubleshooting procedures.
4. Identifying bad components by isolating them: If necessary, remove a component in
question from the chassis, and test it in isolation to make sure that it works properly.
Replace a bad component with a good one.
5. Check and change one component at a time instead of changing several items at the
same time. This will help isolate and identify the problem.
6. To fi nd out if a component is good, swap this component with a new one to see if the
system will work properly. If so, then the old component is bad. You can also install the
component in question in another system. If the new system works, the component is
good and the old system has problems.
