Network connection port test fixture

Abstract

A network connection port test fixture is used for testing a mainboard to be tested. The network connection port test fixture comprises a first control unit, a first port, a second port, a first loopback circuit, a second loopback circuit, a first switching unit and a second switching unit. The first port and the second port are used for being connected to a third port and a fourth port of the mainboard to be tested. In the first test mode, the first control unit controls the first switching unit to conduct the first port and the second port to the first control unit, outputs a set voltage from one end, and detects whether the set voltage is received at the other end to judge whether the mainboard to be tested is normal or not. In the second test mode, the first control unit controls the first switching unit to conduct the first port and the second port to the first loopback circuit respectively.

Description

technical field [0001] The present invention relates to a network connection port test fixture, in particular to a network connection port test fixture suitable for various test modes. Background technique [0002] Generally speaking, in order to ensure the normal use of the network function and its wiring on the main board, each network port will be connected to other test fixtures in different ways during the process of R&D design and even before production. Perform data transmission and reception to determine whether each network port is operating normally. In detail, the tester must also replace the connection components or test fixtures connected to the network ports according to the different test types. For example, when the motherboard is testing the PTC mode (Pass through control mode; PTC mode or called by pass mode), the network port needs to be connected to the test board for testing, and when testing the NIC mode (network interface controller mode; NIC mode) ,...

AI Technical Summary

Problems solved by technology

[0003] Due to the need to make a variety of different connection test boards for different tests, in addition to greatly increasing the cost of testing, it also increases the time and management of tester replacement Trouble

On the other hand, when testing the PTC mode of the traditional main board, the tester still needs to access the test result report to judge whether the main board is normal or not, and cannot find faults and eliminate problems in time
