You don't have all the prints then. I have prints outlineing your two +:
Module Utilization:
Slot 9: M930 /Stack
Slot 8: G231
Slot 7: G110
Slot 6: G231
Slot 5: G110
Slot 4: M930 / Stack
Slot 3: M7261
Slot 2: M7260
Slot 1: Bf11 / M9970 / Km11A / KM11B
(16k)
I have 3 different print sets as the company I got all this equipment from
was an inital beta test site for the 11/05.
