The S5320-EI series enhanced gigabit Ethernet switches (S5320-EI for short) are next-generation energy-saving switches developed by Huawei to meet the demand for high- bandwidth access and Ethernet multi-service aggregation. Based on the cutting-edge hardware and Huawei Versatile Routing Platform (VRP) software, the S5320-EI provides a large switching capacity and high-density GE ports to implement 10 Gbit/s upstream transmissions. The S5320-EI is for use in various network scenarios. For example, it can function as an edge device on the MAN, an access or aggregation switch on a campus network, a gigabit access switch in an Internet data center (IDC), or a desktop switch to provide 1000 Mbit/s access for terminals. The S5320-EI is easy to install and maintain, reducing workloads for network planning, construction, and maintenance. The S5320-EI uses advanced reliability, security, and energy conservation technologies, helping enterprise customers build a next generation IT network.
