AI Technical Summary

Technical Problem

Existing Ethernet blade switches suffer from problems such as insufficient heat dissipation, signal crosstalk and transmission loss, inadequate interface modular design, poor adaptability, and lack of unified management during high-speed data transmission, resulting in performance degradation and limited scalability.

Method used

It adopts a high-density modular architecture and a layered heat dissipation system with multiple airflow channels. The interface modular design layout is optimized, with modular interfaces arranged horizontally along the front end of the switching blade. Combined with the BMC module, hardware resource management is carried out to achieve signal isolation and quick replacement or upgrade of interface types.

Benefits of technology

It improves the heat dissipation efficiency of Ethernet blade switches, reduces signal crosstalk, enhances interface adaptability and scalability, provides efficient internal interconnect communication, and reduces maintenance costs.
