System, device and method for testing power over Ethernet (POE) function

Abstract

The invention discloses a system, a device and a method for testing a power over Ethernet (POE) function. The system comprises tested power sourcing equipment (PSE) ports and a power over Ethernet (POE) function test device, wherein the tested PSE ports connect Ethernet line pairs carrying data signals and electric signals with corresponding ports of the POE function test device respectively; and the POE function test device has ports and transformers, is used for connecting all the Ethernet line pairs which are led in through the ports with corresponding transformers respectively, and separates the electric signals and the data signals through the transformers. The system, the device and the method are compatible with test on the POE function of the Ethernet PSE having different power supply schemes and also compatible with test on POE function of the Ethernet PSE of gigabytes and megabytes, and have the advantages of low cost and simple operation.

Description

technical field [0001] The invention relates to the field of Ethernet equipment testing, in particular to a system, device and method for testing Ethernet equipment with Ethernet power supply function. Background technique [0002] The traditional Ethernet device interface only provides data signal transmission function, while related network devices require local power supply in addition to data connection, which brings some inconvenience to integrated wiring. [0003] With the rapid development of communication technology, Ethernet devices with Power Over Ethernet (POE, Power Over Ethernet) function can provide high-quality information transmission for terminal devices such as Ephone and WLANAP to comply with 802.3af and 802.3at standards The remote power supply eliminates the trouble of additional sockets and wiring, not only realizes power supply to Ethernet equipment, but also reduces the complexity and cost of wiring of communication equipment. [0004] For example, a...

AI Technical Summary

Problems solved by technology

[0005] In order to facilitate the POE function test of PSE equipment, different POE test devices have appeared on the market, but there are still some shortcomings, one of which is compatibility issues: IEEE802.3af and IEEE802.3at standards provide two power supply methods, That is, the PSE device uses the data twisted pair 1, 2 and 3, 6 to supply power, or uses the idle twisted pair 4, 5 and 7, 8 to supply power to the powered equipment

[0008] How to be compatible with the above different power supply methods and / or different Ethernets, and use the same equipment to complete the POE function detection of the above various PSE power supply equipment has not been resolved.
