Huawei Network Switch S5720S-28X-LI-24S-AC 16 x Gig SFP ports 4 x 10 Gig SFP+ ports S5720S-28X-LI-24S-AC Overview The S5720S-LI is a next-generation energy-saving gigabit Ethernet switch that provides flexible GE access ports and 10 GE uplink ports. Building on next-generation, high-performance hardware and the Huawei Versatile Routing Platform (VRP), the S5720S-LI supports intelligent stack (iStack), flexible Ethernet networking, and diversified security control. It provides customers with a green, easy-to-manage, easy-to-expand, and cost-effective gigabit to the desktop solution. In addition, Huawei customizes specialized models to meet customer requirements to suit special scenarios. The models with front power sockets can be installed in the 300 mm deep cabinet. They can be maintained through the front panel, saving space in small equipment rooms. The models that use a fan-free design reduce power consumption and noise.
