v If the operating system is AIX, perform "Verifying the replacement part using AIX diagnostics" on page 30 v If the operating system is Linux, perform "Running the standalone diagnostics from CD-ROM" on page 25 The failing function codes are listed in numerical sequence. A function may not be physically packaged on the same FRU in different system units. When this condition exists, the FRU part number for each type of system unit is listed. The Failing Function Code list is organized into the following columns: Failing Function Code - The failing function code number from the "SRN tables" on page 110. Machine type/model - This column is used when the failing function is on a FRU which differs by machine type and model. Use the part number for the type of system unit you are servicing. Note: Although the machine cover logo may depict the model number as four digits, the service and parts ordering system requires three-digit numbers. For example, if the cover logo depicts model number xxxx, service and parts documentation may refer to that model as xxx. Part number - This column contains the part number of the FRU that contains the failing function. Use the part number for the type of system unit you are servicing. Failing Function Code 151 151 152 166 210 212 Description and notes - This column contains the description of the FRU and any usage notes. The FRU description may be different in different system units. Use the one for the type of system unit you are servicing.
