CSIP Level 1 Troubleshooting: All Troubleshooting Starts Here
- Software failure or corruption: Even if a fix is realized by reloading software, the cause of
the failure or corruption needs to be investigated: Is there a system architecture failure, is
the user doing anything to cause the problem?
- Operator-induced: Is the user expecting more than the system is designed to deliver,
exceeding the capability of the system, or mis-operating it (over-filling the hard drive,
pulling the plug, or other)? A solution can be more user training or a work-around. Inves-
tigate to see if an option ought to be enabled or if there is an enhancement scheduled in
a future release that might solve the problem.
- Environmental: Are there any electrical power, EMI/RFI, or network connectivity difficul-
ties external to the system affecting its performance?
• Verify more easily checked factors first, such as system setup/configuration.
• If you haven’t already, verify that all system voltages are present and within tolerance.
• Conduct tests from Section 6, “Performance Tests” as required to determine if and how the
system is failing.
Developing a
Solution
When think you know what the problem is, decide what changes you need to make to correct
the problem and write down the steps you want to take to make the repair, especially if the
sequence of your actions is important. Even if you don’t think you need to do this for yourself, it
can be useful to others when you properly document the problem and its resolution. You may
benefit from this yourself in the future.
Implementing a
Solution
Implement your solution by performing the corrective actions you developed. Proceed cau-
tiously and systematically. Make only one change at a time, and verify that the change you made
brings about the result you expected before making any other change.
It is not unusual for another problem to surface when you are applying changes to fix what you
thought was the problem. If the change didn’t bring about the result you expected, consider if
