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.￿
