The method for activating a service on a principal device being connected, via a port connector comprising a set of pins, to a device suitable to provide an Ethernet service to the principal device, the set of pins having a first subset and a second subset of pins, wherein the first and the second subset of pins have no pins in common. The method comprises the steps of sensing always in an initial state for a Fast Ethernet service at the first subset pins and for a second service at the second subset of pins; detecting which of the Fast Ethernet service and the second service is signaled on the first and the second subset of pins; in case the second service is detected, then selecting the second subset of pins and activating the second service on the principal device; and in case the Fast Ethernet service is detected, then disabling the second service, selecting the first subset and second subset of pins and activating the Fast Ethernet service; and further, if a Gigabit Ethernet service is possible, enabling the Gigabit Ethernet service instead of the fast Ethernet service. |
