Problems solved by technology

However, in actual use, the terminal equipment connected to the hub is very different, and the power supply provided by the hub may not be suitable for the terminal equipment, or the two pairs of pins 4 / 5 and 7 / 8 of the interface have been defined for other purposes, such as 100M industrial The 4 / 5 and 7 / 8 groups of wires connected to the Ethernet switch have been used for other purposes, so the above-mentioned invention cannot at least adapt to a 100M Ethernet switch, and there are great limitations

Embodiment Construction

[0022] see figure 1 , figure 2 , the switch includes a network communication management module 1, a switch interface 2, an overload protection circuit and a redundancy management circuit 3. The network communication management module 1 includes a network transformer 11 , a signal transceiver controller 12 , a switching engine 13 and an address table 14 . The switch interface 2 of the present invention adopts the RJ45 interface. The primary side of the network transformer 11 is connected to the pins 1 / 2 and 3 / 6 of the RJ45 interface 2 for receiving the Manchester code signal (Manchester Code) from the RJ45 interface 2, and the secondary side is connected to the signal transceiver controller 12, and the transceiver controller 12 It is connected with the switching engine 13, and the switching engine 13 is connected with the address table 14. The switch receives the Ethernet frame from a port, and sends it to the Ethernet signal transceiver controller 12 through the Ethernet n...

Abstract

This invention provides an ethernet exchanger and its method to realize the redundance supply. The exchanger comprises exchanger interface and network communication management module, wherein the network management module comprises network transformer, signal receiving and sending controller and exchange engineer and address. The exchanger comprises voltage modulation circuit of bus supply, wherein the network transformer is connected with voltage modulation circuit. The direct power output is connected with voltage modulation circuit or exchanger interface lead leg.

Description

technical field [0001] The invention belongs to the field of network communication and industrial control, and in particular relates to an Ethernet switch for realizing redundant power supply and a method for realizing redundant power supply. Background technique [0002] Both Ethernet switches and hubs play the role of "hubs" in network data transmission. With the development of hub products, from traditional hubs to intelligent hubs, and then to switching hubs, the boundaries between hubs and switches have become blurred. Switches or hubs in the known technology can only realize the forwarding of Ethernet communication signals usually, but cannot supply power to terminal equipment, so it is more suitable for the connection of automated office equipment (such as computers); but for IP phones, network cameras, Especially for equipment such as transmitters and actuators on industrial sites, additional power supplies are required, which not only brings inconvenience to cable ...
