Hi KenB i am looking at the slot configuratation and i cannot see any problems as the book states that the ivp8 if installed must be in a higher slot than the station card and cannot be placed into slot 18. I need some serious assistance in determining what is the maximum port availability for this system with the cards that have been placed into the system.

This is what i gathered

Base cabinet:
slot 11- 8 digital stations
slot 12- 4 co lines
slot 13- 4 single line stations
slot 14- 4 dtmf recievers

Expansion Cabinet:
slot 15- kcdu 2 co lines and 4 digital stations
slot 16- pdku2 8 digital stations (this card is causing the ivp to shut down)
slot 17- ivp8 strategy dk
slot 18- nothing
