Hi,
As far as I know You need to put sup720 in the middle slots, that is 5&6 for 6509, becouse it makes the switched fabic (256 gbps and 100 mpps )bus availabe for all modules. There are three kinds of modules:
- non switched fabric enables modules, they are using only standard bus (32 gbps) to communicate,
- 1rst Generataion Switched fabric, one connection to bus and one to switched fabric bus,
- 2nd Generation Switched fabric, two connections to switched fabric bus.
Supervisor is connected to both standard bus and switched fabric bus. Communication between non-fabric enabled modules and 2nd generation is only available through the supervisor engine.
Read this, it should clearify the doubts:
