Determining a Part Position and Item From the Direct Select Address:
1. Break down the DSA into the bus number, the multi-adapter bridge number
and the multi-adapter bridge function number as shown in the Table 7.
2.
Use the System Configuration List or Hardware Service Manager (HSM) to
determine if the bus is located in the system unit or an I/O tower.
3. Refer to the “Card Position Tables” on page 282. Search for the bus number, the
multi-adapter bridge number and the multi-adapter bridge function number in
the Card Position Table that matches the system unit or the I/O tower type
where the bus is located.
