1. Are you working from the serviceable event view and a card location is listed with this failing item, or do you already know the unit or feature type where the failure is?
   • Yes: The listed card location is where the error is located. Continue with the next step.
   • No: Record the bus number value, BBBB, in word 7 of the reference code. Word 7 of the reference code allows you to determine the correct bus number, bus type, multiadapter bridge number, multiadapter bridge function number, and logical card number from the Direct Select Address (DSA). See DSA translation. Continue with the next step.
2. Use the following table to determine the part number for the field replaceable unit (FRU).

   CCIN or FFC	Type and model	Part number	Description	Location code
   	5796, 7314-G30	See System parts.	I/O backplane	Un-P1
   	5802, 5877	See System parts.	I/O backplane	Un-P1
   	5803, 5873	See System parts.	I/O backplane	Un-P1, Un-P2

   If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.

This ends the procedure.
