Connection Mode Parameter
The connection mode parameter refers directly to the physical topology in which the SCE 2000 is installed. The connection mode depends on two factors:

•
•Cascade — Indicates a two SCE 2000 topology where the SCE 2000s are connected via the cascade ports.
The connection mode parameter is determined by the physical deployment of the SCE 2000, as follows:

•Single SCE 2000 external switch installation =
•Two SCE 2000 inline installation =
