This ends the procedure.
MASBUS
MASBUS: multi-adapter bridge card location.
The multi-adapter bridge detected a problem with a physical card location that it
controls. The problem is either in the bus between the multi-adapter bridge and
the card slot or with the card slot. The card location may or may not have an
installed card.
1. If you are working from the Service Action Log and a card position is listed
with this failing component, then that is where the error is located, continue
with the next step in this procedure. Otherwise, record the bus number value,
BBBB, in word 7 of the SRC, see “Breaking Down The SRC” on page 280 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 item. Record the frame or tower type.
2. The failing component is the FRU containing the logical card slot controlled by
the Multi-adapter bridge. Identify the tower type indicated by the location in
the SAL or where the bus number, BBBB, is and exchange the FRU indicated in
the table below using the information provided in the table.
