PHY mode autonomous switching signal test system

Abstract

The invention relates to a PHY mode autonomous switching signal test system. The system comprises: an MDIO control module which is used for switching the working mode of a network PHY of a to-be-tested board card into an electrical port mode or an optical port mode; a PHY chip module which is used for constructing an electrical port test channel and an optical port test channel and performing signal test on the to-be-tested board; a network signal acquisition module which is used for verifying the electric port test channel to obtain an electric port test result; an oscilloscope test module which is used for performing verification through the optical port test channel to obtain an optical port test result; and a computer operation terminal which is used for collecting an electric port test result / port test result. The beneficial effects of the invention are that the MDIO control module is used for controlling an optical port test and an electrical port test, and the connectivity of the electrical port test channel and the optical port test channel is judged, thereby achieving the testing of a to-be-tested board card, achieving the autonomous switching of the optical port test andthe electrical port test, and improving the testing speed and testing convenience.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a signal test system for autonomous switching of PHY modes. Background technique [0002] With the development of cloud computing and big data technology, the demand for server system resources increases accordingly. Processor suppliers realize the overall upgrade of system resources by improving the computing power of the processor and upgrading the multi-processor platform, which greatly improves the data capacity of the entire system. Processing capacity, the ever-increasing demand for business computing chip circuits is constantly squeezing the board space of network chip circuits. In the current server motherboard card, two MACs are usually integrated inside the BMC, one of which is connected to the external Ethernet switch board through the PHY to facilitate communication with other modules connected to the Ethernet switch board, and the other is used as the on-board d...
