1. The Device Number (first digit) of the SRN indicates where the
FRU for the first SRA number is located. The FRUs for the
other SRA numbers may be located in other devices. When the
SRN is displayed, the locations of the FRUs are also displayed.
If needed, run the diagnostics to locate the device containing
the FRU.
The rightmost digit of the SRA identifies the FRU location.
When the rightmost digit is a 0, either the FRU location could
not be determined or the FRU is always in the same location. If
needed, see page 2-20.
Use the Removal Procedure referenced in the data for your SRA
number and exchange the FRU.
