Network power switching device

This creation is about a network power exchange device, especially a network power exchange device that uses a light signal display to quickly understand the wattage consumption.

Existing Ethernet switches or power exchanges typically use LEDs to display the status of network devices. In general, most of them only show whether they are connected or not. For users, information content can only be quickly confirmed. Taking the Ethernet-powered switch as an example, it is designed to design one more light to indicate whether it is in power supply or in use.

As shown in FIG. 1, the network switch is provided with a display panel having a connection port 10 and light emitting diodes 11, 12. Each port 10 is shown by two LEDs 11, 12, one in the twisted pair state and the other in the Ethernet state. This message is provided to the user only if the connection 10 is in use, and does not provide information for the entire machine, such as the wattage of the entire machine. However, in use, the Ethernet power supply converter has an upper limit on the wattage of the power supply based on the size of the casing and the power supply cost, for example, a 60 watt, 100 watt power supply. However, in the current Ethernet network power supply standard, the IEEE802.3af protocol of the network communication protocol, and the power supply terminal is exemplified by 15.4 watts per watt, the wireless power needs to be more than 60 watts, and the IEEE802.3at for the network communication protocol, the power supply end Each raft is 30 watts, and four rafts are required to reach 120 watts. Take the example of using a 100 watt power supply. If the setting is to occur in an unmanaged environment, it will reach 90 watts when using 3 machines, and when the fourth device is connected, it may be turned on to 10 watts, so the manager will regard this 100 The Ethylene Ethernet power supply switch is sufficient for use, and the administrator does not know that the device is fully loaded. Therefore, the indicator light only informs the four powered devices that they are activated, but cannot tell the actual load. When any of the power receiving devices exceeds the wattage, resulting in a total wattage exceeding the rated value, for example, 100 watts, the Ethernet switch may be overloaded at any time. When it occurs, if the environment used is an application that needs to be online at any time, unnecessary losses may occur.

Referring to Figure 4, a second embodiment of the network power switching device 13 of the present invention is described as an unmanaged network power switching device. The difference between the second embodiment and the first embodiment is that the packet switch 20 of the second embodiment is not electrically connected to the microprocessor 16, so that the packet switch 20 is not controlled by the microprocessor 16, so the microprocessor 16 is selected. A lower specification microprocessor can be selected to reduce or reduce costs. Therefore, the packet switch 20 directly uses the system DC voltage SV to perform packet exchange with the at least one network power receiving device 30 through the at least one network port 24, and the other components operate in the same manner as the first embodiment, and details are not described herein.
