The official source of Retail Store Solutions Field Replacement Unit (FRU) part numbers is the Hardware Service Guide. These guides provide detailed information about problem determination, servicing and the list of official Field Replacement Unit part numbers for the machine in question.
When you know the marketing 'Feature Code', an alternate source of information to help identify FRU part numbers is the Retail Store Solutions Pictorial Guide to Features. This is an unofficial publication provided 'as-is' and should be considered a supporting document to the Hardware Service Guide. If you are in any doubt to the accurateness of part number information contained in these guides, you should defer to the Hardware Service Guide or contact Techline.
