6. Use the following figure to understand how addresses in the bus/board/card format relate to the
bus-bus-bus-bus/card-card/board-board format. You can also use the figure to understand how
addresses in the bus, board, and card format relate to the direct select addresses used in Part
locations and location codes.
Figure 3. Format conversion
Note: When converting from bus/board/card format to bus-bus-bus-bus/card-card/board-board
format, the numbers must be converted from decimal to hexadecimal.
Go to step 10 on page 16 for IOA and device address information.
7. Display the field-replaceable unit (FRU) details for the problem that you are attempting to fix. The
location information in the FRU detail is only available for IOPs, IOAs, and devices.
Is the FRU an IOP, IOA, or device, and is there location information in the Location field of the
display?
Yes: Use the location information and return to the procedure that sent you here. This ends the
procedure.
No: Continue with the next step.
