The header frame is configured for mating with at least one circuit card. A plurality of cable connectors are received in the header opening. Each cable connector has cables extending therefrom and each cable connector has a header holding signal contacts at a mating end of the header and configured for mating with a corresponding card connector of the corresponding circuit card. Cable connector mounts are coupled to the end walls and extend into the header opening. The cable connector mounts engage corresponding cable connectors to secure the cable connectors in the header opening.
