the bus number value, BBBB, in word 7 of the SRC, see “Breaking down the SRC” on page 63
(located in the Bus PIP Overview topic) for help in determining the bus number. Search for the bus
number in HSM or the System Configuration Listing to determine which frame or I/O tower contains the
failing component. Record the frame or tower type.
2. The failing component is the FRU containing the logical card slot that is controlled by the multi-adapter
bridge. Identify the system model, tower, expansion unit, or machine type that is indicated by the
location in the SAL, or by using the bus number, BBBB. Using the information provided in the table
below, exchange the FRU that is indicated.

The Motor Drive Assembly (MDA) may be the failing item.
1. Use the table below to find the part number you need.
2. Refer to the Models 870 and 890 - MDA (air mover) controller remove and replace procedure.
3. See Type, model, and part number list for the part number.
Note: Before replacing any FRU’s verify that all cables are seated correctly.
