6 Troubleshooting If you are having problems with your system, please try the following initial steps: Simplify the System – Remove modules one at a time from your system to see if there is a specific module that is causing a problem. Perform you troubleshooting with the least number of modules in the system possible. Swap Components – Try replacing parts in the system one at a time with similar parts to determine if a part is faulty or if a type of part is configured incorrectly.
