Information is obtained from a module received in a slot in a chassis. The information includes a number of ports in one or more module connectors which route at least one communication channel associated with a communication interfaces on the module. A determination is made as to the number of ports the slot has a capability to route the at least one communication channel to one or more backplanes in the chassis and to another module received in another slot in the chassis. A given number of ports in the one or more module connectors are enabled to forward data from the communication interface on the module and through the at least one communication channel to the other module based on the determination.
