removeandreplacetheFRU.Makesuretoobservethefollowinggeneralrules:
1. Donotattempttoserviceanycomputerunlessyouhavebeentrainedand
certified.Anuntrainedpersonrunstheriskofdamagingparts.
2. BeforereplacinganyFRU,review“FRUreplacementnotices”onpage 25.
3. BeginbyremovinganyFRUsthathavetoberemovedbeforethefailingFRU.
AnyofsuchFRUsarelistedatthetopofthepage.Removethemintheorder
inwhichtheyarelisted.
4. FollowthecorrectsequenceinthestepstoremovetheFRU,asgiveninthe
figuresbythenumbersinsquarecallouts.
5. WhenturningascrewtoreplaceanFRU,turnitinthedirectionasgivenby
thearrowinthefigure.
6. WhenremovingtheFRU,moveitinthedirectionasgivenbythearrowinthe
figure.
7. ToputthenewFRUinplace,reversetheremovalproceduresandfollowany
ofthenotesthatpertaintoreplacement.Forinformationaboutconnecting
andarranginginternalcables,see“Locations”onpage 44.
8. WhenreplacinganFRU,usethecorrectscrewasshownintheprocedures.
Attention:AfterreplacinganFRU,donotturnonthecomputeruntilyouhave

arelooseinsidethecomputer.Verifythisbyshakingthecomputergentlyand
listeningforrattlingsounds.Metallicpartsormetalflakescancauseelectrical
shortcircuits.
Attention:Themainboardissensitiveto,andcanbedamagedby,electrostatic
