This manual presents complete and concise step-by-step procedures for the disassembly of the chassis assemblies and the removal of all boards included in the 2005 SXRD chassis. As it is with any
chassis disassembly or assembly process, care must be taken to remove chassis components without damaging the boards, wiring, or the chassis itself.
The procedures in this manual guide you through effective and efficient disassembly and reassembly
processes for all areas in the 2005 SXRD chassis.
How to use this manual:
1) The manual can be sequentially followed from Chapter 1 through Chapter 7 for removal of
the major chassis assemblies and the individual boards.
Chapter 8 illustrates the Screen Frame Assembly Removal
Chapter 9 is a quick reference for wire routing throughout the chassis.
2) The chapters in the manual are also designed as stand alone procedures. Therefore,
you can go directly to any specific chapter and proceed to remove that particular assemble or
board. If the procedures in a previous chapter are necessary it is noted in steps 1 or 2 of the
stand-alone procedure.
