S5720S-52X-PWR-LI-AC HuaWei 48 Port Gigabit 4 10 Gigabit Optical Port Poe Ethernet Switch
HuaWei S5731S-H48T4S-A 48-port Gigabit electric 4 Gigabit optical three-layer core switch
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 HW 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.
HW S5720S-LI series Ethernet switches are only sold in several countries and regions as part of HW’s channel distribution products.

| Operating temperature |
0°C to 45°C (32°F to 113°F) at an altitude of 0-1800 m (0-5096 ft.) NOTE: When the altitude is 1800-5000 m (5096-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (722 ft.). The operating temperature of the switch is 0°C to 40°C (32°F to 104°F) when it uses GE SFP optical modules with 40 km transmission distances. |
