v Otherwise, record the bus number value, BBBB, in word 7 of the SRC, see “Breaking down theSRC” on page 63 (in the Bus PIP overview) for help in determining the bus number. Search for thedecimal bus number in HSM or the System Configuration Listing to determine which frame or I/Otower contains the failing item. From the Hardware Service Manager screen select LogicalHardware Resources —> System Bus resources. Move the cursor to a system bus object andselect Display Detail. Do this for each bus until you find the bus on which you are working. Recordthe frame or tower type.2.
