Important notes:

vOnly certified trained personnel should service the computer.

vBefore replacing any FRU, read the entire page on removing and replacing FRUs.

vWhen you replace FRUs, use new nylon-coated screws.

vBe extremely careful during such write operations as copying, saving, or formatting. Drives in the computer that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten.

vReplace a FRU only with another FRU of the correct model. When you replace a FRU, make sure that the model of the machine and the FRU part number are correct by referring to the FRU parts list.

vA FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. If you suspect that a FRU is defective, clear the error log and run the test again. If the error does not recur, do not replace the FRU.

vBe careful not to replace a nondefective FRU.
