4.1 General
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
according to the section numbers shown in the boxes. Then start removal and replacement.
