(FRUs) in the PC. It may not be necessary to remove all the FRUs in order to replace one.
The chart below provides a guide as to which other FRUs must be removed before a
particular FRU can be removed. The numbers in the chart indicate the relevant section

an FRU that is the potential cause of a computer fault, use the chart to determine the order in
which FRUs need to be removed.
