Read this first

Before you go to the check procedures, be sure to read

this section.

Important Notes

 Only certified trained personnel should service

the computer.

 Read the entire FRU service procedures before

replacing any FRUs.

 Use new nylon-coated screws when you replace

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 could be overwritten.

 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 refer-

ring to the FRU parts list.

 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 recur-

ring problem exists. In this case, clear the error log

and run the test again. Do not replace FRUs if log

errors do not reappear.

 Be careful not to replace a non-defective FRU.

What to do first

The servicer must include the following in the parts

exchange form or parts return form that is attached to the

returned FRU:

1. Name and phone number of servicer

2. Date of service

3. Date when part failed

4. Date of purchase

5. Failure symptoms, error codes appearing on display,

and beep symptoms

6. Procedure index and page number in which failing

FRU was detected

7. Failing FRU name and part number

8. Machine type, model number and serial number

9. Customer's name and address
