1. If you are working from the Service Action Log and a card position is listed
with this failing item 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 tower contains the failing item.
