Only certified trained personnel should
service the computer.
Read the FRU Removal and Replacement procedures before replacing any FRUs.
Be extremely careful during write operations such as copying, saving, or formatting.
Drives in the computer that you are servicing might have been rearranged, or the drive startup sequence might have been altered.
If you select an incorrect drive, data or programs might be overwritten.
Replace FRUs only for the correct model.
When you replace a FRU, make sure the model of the machine and FRU part number are correct by referring to the FRU parts list.
A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur from a variety of reasons that have nothing to do with a hardware defect, such as:
cosmic radiation, electrostatic discharge, or software errors.
FRU replacement should be considered only when a recurring problem exists. If this is suspected, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear.
Be careful not to replace a nondefective FRU.
