empty IOP card positions between IOPs. SPD busses are numbered from
0004 through 0017 in hexadecimal as they appear in the SRCs (see "Breaking
Down The SRC" on page 280). Empty card positions (between I/O
processors) are not allowed on the system SPD bus. Card gaps may cause
system reference codes (SRC) that provide incorrect FRU information. To
determine if there are any card gaps, select the Display card gap information
function key from the Hardware Service Manager display. If there are gaps,
correct the situation.
