SCALANCE XM-400 products permit the configuration of switched networks at the control level, which not only demands high availability of the network and extensive diagnostic options, but also a high number of ports, high transfer rate, and the support of fiber-optic and copper cables and Power over Ethernet transmission.

Thanks to the scalability of the basic unit and the optionally available Layer 3 switching function, the network can be established specially for the relevant application or expanded at any time.
