ThischapterexplainshowtodisassemblethecomputerandreplaceFieldReplaceableUnits
(FRUs).Somereplacementproceduresmaynotrequireyoutoremoveallthesurrounding
FRUstoreplaceonlyoneFRU.ThechartbelowshowstheFRUsintheorderinwhichthey
shouldberemovedinatop-downmanner,irrespectiveoftheirphysicallocations.TheFRUs
showninthetopareaofthechartshouldnormallyberemovedbeforeremovingtheFRUs
showninthebottomarea.ToreplacetheFRUs,firstidentifythesuspectFRUforthesystem
failure.Next,accordingtothischart,determinetheFRUsthatneedtoberemovedbefore
removingthesuspectFRU.AfteryoudeterminethoseFRUs,gototheappropriatesections
