What to do first
When you do return an FRU, you must include the following information in the
parts exchange form or parts return form that you attach to it:
1. Name and phone number of servicer
2. Date of service
3. Date on which the machine failed
4. Date of purchase
5. Procedure index and page number in which the failing FRU was detected
6. Failing FRU name and part number
7. Machine type, model number, and serial number
8. Customer’s name and address
Note for warranty: During the warranty period, the customer may be
responsible for repair costs if the computer damage was caused by misuse,
accident, modification, unsuitable physical or operating environment, or
improper maintenance by the customer.
Notes:
• Only certified trained personnel can service the computer.
• Before replacing any FRU, read the entire page on removing and replacing
FRUs.
• When you replace FRUs, use new nylon-coated screws.
• Be 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.
• Replace an FRU only with another FRU of the correct model. When you replace
an FRU, make sure that the machine model and the FRU part number are correct
by referring to the FRU parts list.
• An FRU should not be replaced just 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 an FRU only when a problem recurs. If you suspect
that an FRU is defective, clear the error logs and run the test again. If the error
does not recur, do not replace the FRU.
• Be careful not to replace a nondefective FRU.
