Process Overview
The troubleshooting process consists of four steps: collecting fault information, determining the fault scope, analyzing the fault cause, and rectifying the fault. Figure 1-1 shows the troubleshooting process.
- Collecting fault information
Fault information is critical to troubleshooting. System maintenance personnel should collect fault information as much as possible.
- Determining the fault scope
Troubleshooting personnel determine the fault scope based on the collected fault details.
- Locating the fault cause
Fault locating refers to a process for finding the root cause of a fault from multiple possible causes. By using certain methods or measures to analyze and compare the possible causes of the fault, the system maintenance personnel finally find the real cause of the fault after excluding impossible causes.
- Rectifying the fault
Fault rectification is a process for rectifying a fault based on different causes of the fault.
- Recording the troubleshooting process
Record key information about the troubleshooting process, and provide preventive measures and workarounds to avoid similar faults.
