- the network component When using a button, the network component must be connected to voltage and ready for operation in order to switch over by pressing the button.
- a further optical display is necessary, as the user or customer of the network component cannot see which operating mode the network component is in after pressing the button, e.g. whether it is in stealth or router operating mode. This is also omitted with the use of at least one plug or one plug, there or more wire bridges, since these can also function as a visual display relating to the selected operating mode.
- Operating mode selection device e.g. furthermore the advantage that these are not considered
- Hardware must be “permanently installed in the device". If switching between different operating modes is no longer used by the user or customer of the network component in a later operation, a DIP switch that is "permanently installed in the device" must remain there, even if it is no longer required for the entire product life cycle should. This is wasteful and can be avoided with the expedient developments relating to the design of the operating mode selection device in such a way that it has a wire bridge or a plurality of wire bridges, or in such a way that it has a plug or a plurality of plugs, since these e.g. can also be reused with other network components, at least of the same type.

Depending on which digital signal input a signal is switched to or which digital one
- Signal input terminal is temporarily electrically connected directly to the signal source, i.e. the digital state of the one subjected to such a signal
- Signal input connection changes from 0 to 1, the selected switchover to a predetermined operating mode takes place.
- control device 200 as the operating mode selection device, for example, with three signal input connections, basically eight different states for the selection of a respectively predetermined operating mode are achieved and it is thus possible to switch between eight different operating modes individually.
- the following table which can also be taken from FIG. 2, illustrates this.
- This embodiment also opens up the possibility of more extensive coding over time to be extremely dynamic and / or between further
- the several different states described above are used jointly over a predetermined period of time for the respective selection of a predetermined operating mode to which a switch is then made.
- the several different states described above are expediently present at fixed, prescribed time intervals, i.e. at fixed, prescribed time intervals, a different state is set by applying one or more signals to one or more digital signal input terminals. This is because it is easy to see whether coding takes place over time or not. There is thus none in these at fixed, prescribed time intervals and / or in this predetermined period of time
- the device according to the invention and using the method according to the invention can thus e.g. in the case of an (initial) commissioning of one as described above
- Network components query the product-specific firmware housed therein for the status of the digital input. If there is a signal at a digital input, e.g. by means of the wire bridge S2 ‘according to FIG. booted up in stealth operating mode and the network component is thus not visible in the network, in particular the Ethernet network, but protects possible other network components located "behind” the network component in the network, appropriately with a preconfigured profile. This is therefore a simple "Plug & Protect commissioning mode" for the benefit or customer.
- the network component is switched to the preconfigured operating mode or the network component is started up in the preconfigured operating mode, with. If e.g. switched to the router operating mode or in this
- the user or customer can now access the web-based management via a computer as usual and configure the network components individually if necessary.
- the customer then also has the Possibility to individually adapt or deactivate the preconfigured operating mode and / or use the digital signal input connection for other functions.
