Abstract
An Ethernet switch has a header device with a crossbar device and a number of downstream interface modules with a first number of a series of ports and a second number of a series of ports, respectively, such that in each case the same one in the series of the first number of ports is connected to a switching control unit coupled to an interface device, and the further ports in the series of the first number of ports are connected to a port in the second number of the series of ports via respective data lines routed in cascade form.

An interface module (2a, 2b, 2c, 2d) comprising:
- a first number of a series (5a, 5b, 5c, 5d) of ports (51a, 52a, 53a, 54a, 51b, 51c, 51d) and
- a second number of a series (6a, 6b, 6c, 6d) of ports (61a, 62a, 63a, 64a), where a first port (51a, 51b, 51c, 51d) in the first number of a series of ports (51a, 52a, 53a, 54a, 51b, 51c, 51d) is connected by means of at least one data line to a switching control unit (3a, 3b, 3c, 3d) connected to an interface device (4a, 4b, 4c, 4d), and where
- the subsequent input ports (52a, 53a, 54a) in the first number of a series (5a, 5b, 5c, 5d) of ports are connected in order by means of at least one respective data line to the ports (61a, 62a, 63a, 64a) in the series of the second number of a series (6a, 6b, 6c, 6d) of ports, starting with a first (61a) in the series of the second number of ports.
An Ethernet switch comprising a header device (1) with a crossbar device (7) and a number of downstream interface modules (2a, 2b, 2c, 2d), particularly a number of downstream interface modules, having a first number of a series (5a, 5b, 5c, 5d) of ports and a second number of a series (6a, 6b, 6c, 6d) of ports, respectively, such that in each case the same one (51a, 51b, 51c, 51d) in the series of the first number (5a, 5b, 5c, 5d) of ports is connected to a switching control unit (3a, 3b, 3c, 3d) coupled to an interface device (4a, 4b, 4c 4d), and the further ports (52a, 53a, 54a) in the series of the first number (5a, 5b, 5c, 5d) of ports are connected to a port in the second number (6a, 6b, 6c, 6d) of the series of ports by means of respective data lines routed in cascade form.
A method for providing a multiplicity of switchable Ethernet terminals (4a, 4b, 4c, 4d), where a crossbar device (7) is connected to a multiplicity of separate multipole data lines (B1, B2, B3, B4) having switching control units (3a, 3b, 3c, 3d), which can be lined up in modular fashion and are associated with respective Ethernet terminals (4a, 4b, 4c, 4d), by means of a respective predefined data line (B1, B2, B3, B4).
