How to use the parts lists and diagrams
The figures in this chapter show the major subassemblies in the product and their component parts. A parts
list table follows each exploded view assembly diagram. Each table lists the item number, the associated
part number, and the description of each part. If a part is not listed in the table, then it is not a field
replacement unit (FRU).
CAUTION: Be sure to order the correct part. When looking for part numbers for electrical components, pay
careful attention to the voltage that is listed in the description column. Doing so will ensure that the part
number selected is for the correct all-in-one model.
NOTE: In this manual, the abbreviation “PCA” stands for “printed circuit-board assembly.” Components
described as a PCA might consist of a single circuit board or a circuit board plus other parts, such as cables
and sensors.
