Embodiment Construction

[0039] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0040] Firstly, the specific implementation of the test method and device is introduced, and then how to apply the test device to the specific implementation of the test of the switch with PoE function is described.

[0041] figure 1 It is a schematic diagram of the implementation process of the test method of the PoE function switch, as shown in the figure, including the following steps:

[0042] Step 101. Feedback a response signal representing the power of the powered equipment and the power of the powered equipment when receiving the detection pulse of the powered equipment;

[0043] In step 101 , the components that receive pulses for feedback can use chips that comply with the PD regulations in the 802.3af standard. Generally, such chips are used in PDs such as Power over Ethernet VoIP telephones and APs. It can represent itself as a standard P...

Abstract

The invention discloses a testing method and a device of an Ethernet exchanger with the power supply function, comprising that: the transmitted signal of the exchanger is received, the AC signal of the transmitted signal is passed by for carrying out the test on the data exchange function; when the detection pulse of a power device is received, the feedback of the response signal with the characteristics which pertain to the power device and the power of the device is carried out; the DC signal is output in the transmission signal after receiving the response signal by the exchanger; the DC signal is extracted after the isolation of the DC signal of the transmission signal; and whether the power output of the exchanger is normal or not is determined by the test of the DC signal. The usage of the method can allow the testing device to have the simple structure and the cheap cost, compared with the prior proposal which needs the real power device to carry out the test, the method has better operatability.

Description

technical field [0001] The invention relates to a test technology of a switch, in particular to a test method and device for a PoE function switch. Background technique [0002] PoE (Power over Ethernet, Power over Ethernet) is a technology that uses twisted-pair cables (Twisted-PairCable) to transmit electrical energy, defined by IEEE802.3af. In this technology, power and data signals are transmitted on the same bundle of twisted pairs, thereby reducing the wiring complexity and cost of communication equipment. [0003] The PoE standard stipulates that the switch port needs to determine whether the connected device is a PD (Powered Device, powered device), and only allows power supply to PDs, but not to non-PDs; and, after judging that the access device is a PD, it is necessary to further judge the PD The level of the PD determines the output power according to the level of the PD. There are 5 levels of PD specified in the standard. For these 5 levels, PoE switches have c...
