The failing item is the tower card in an I/O unit.
- Are you working from the serviceable event view and a card location
is listed with this failing item?
- Yes: Then 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 (see DSA translation).
Search for the bus number in the HMC's or operating system's resource and
configuration interfaces or the System Configuration Listing to determine
which unit contains the failing item. Continue with the next step.
- The failing item is built into the I/O backplane of
the I/O unit. Use the following table to determine the part number for the field replaceable unit (FRU):
