Connection unit for patch cables of power-over-ethernet networks with an embedded switch controlled by a central control system

摘要

The connection unit is intended for connecting terminals (T) to networks (LAN) that provide electric energy (E) to the terminals (T) connected thereto. The connection unit (AE) is configured for generating electric energy for the connection unit (AE) from the energy (E) provided, and has a switching element (SE) for separating the supply of energy for the terminals (T), wherein the switching element (SE) is controlled via the network (LAN). It is advantageous that the energy supply of the terminals (T) can be separated or switched on via the network (LAN) by means of the switching elements (SE), for example as a function of the presence or the location of users of terminals (T). Since the separations of the energy supply to the terminals may be carried out over longer periods of time, such as during the night, the energy consumption of the terminals (T) or of the networks (LAN) providing the electric energy to the terminals (T) can be reduced significantly.
