4.5 Fault Repair and Troubleshooting
If a fault occurs during system operation, always acquire the dump if possible (by trying to acquire
the dump actually).
If the dump can be acquired, issue the difficulty through the appropriate route to request the
detailed analysis.
For troubleshooting, basically execute the POST and T&D program to check whether a hardware
error occurs or not. Then any error indication appears on the display.
Figure 4.1 shows the flow of the troubleshooting based on the POST and T&D program.
