Read this first
Before you go to the checkout guide, be sure to read this
section.
Important Notes:
v
Only certified trained personnel should service the
computer.
v
Read the entire FRU service procedures before
replacing any FRUs.
v
Use new nylon-coated screws when you replace
FRUs.
v
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 could be overwritten.
v
Replace FRUs only for the correct model. When you
replace a FRU, make sure that the model of the
machine and FRU part number are correct by referring
to the FRU parts list.
v
A FRU should not be replaced because of a single,
unreproducible failure.
Single failure can occur for a
variety of reasons that have nothing to do with a
hardware defect, such as: cosmic radiation, electrostatic
discharge, or software error. FRU replacement should
be considered only when a recurring problem exists. In
this case, clear the error log and run the test again. Do
not replace FRUs if log errors do not reappear.
v
Be careful not to replace a non-defective FRU.
