For flexible use with both the thin and thick cables, each port is equipped with a BNC and AUI connector. To select a connector, no switch setting needs be made. The repeater automatically knows which connector of the port is used. The dual interfaces of each port allow reconfiguration of the connected segments. For any port, the thick cable can be removed and the thin cable connected, or vice versa, anytime without first turning off the repeater's power.
Users press the reset button instead to re-initialize the repeater.
