Step 3. At this point you will have a good idea about which area of the system requires further analysis.
For example, if the symptom was “system will not power-up” then the initial troubleshooting
procedure may have indicated a problem with the DC power supply not coming up after the power
switch was turned on.
Step 4. You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been
identified and need to be replaced. You must now perform the specific remove-and-replace
verification steps.
NOTE If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed
unless all identified failed FRUs are replaced.
Step 5. There may be specific recovery procedures you need to perform to finish the repair. For example, if
the display panel is replaced, you will need to restore customer-specific information.
