Addressing servers in a cascade
The addressing format used by the ServSwitch CX units incorporates the various group numbers along with a final specific port number to which a required server is attached. In the diagram given here, a portion of the previous cascade diagram indicates how the routes to particular servers are formed and addressed.
Each cascade level requires two digits, hence the server marked in red requires a unique address with six digits because it is at cascade level 3, compared to the blue server at level 2 with its four digit unique address. A server connected directly to the ServSwitch CX at the top level would simply have a two digit port number.
The group at level 2 is numbered 41 because it is a quad group, connected to ports 1, 2, 3 and 4 on the ServSwitch CX. If it was connected to ports 5, 6, 7 and 8, then the group number would be 42 and the overall address for the red server would be 43 42 02.
