? [Multi-scenario and Large-scale Application]: This series of unmanaged switches are fast ethernet switches designed for high-forwarding network environments such as schools, families, SMEs and mini-monitoring. ? [4KV Lighting Protection]: The gigabit ethernet switch designed with lightning protection, it can withstand 4000 volts or more lightning, and prevent circuit failure. Built-in protection circuit. When a short circuit or overload occurs, the port will automatically fuse to protect the safe operation of the switch and other ports. ? [Metal Case and Fanless Design]: The metal body of computer networking switches have excellent resistance to falling, and most accidental falls will not affect the functional use of the switch. The fanless design does not generate noise and also has good heat dissipation performance. The normal operating temperature range of network hub is - 10 to 55 ?, which is safe and worry-free. ? [VLAN Mode]: When the VLAN button is on, port 1 to port 8 are isolated from each other and communicate with port 9 and port 10 (uplink ports) only, which improve the network processing capacity and enhances the security of the LAN. ? [Plug and Play]: The ethernet hub is simple setup with no software to install or configuration needed. Each port supports MDI/MDIX auto-flip and duplex/rate auto-negotiation. And with no configuration necessary making it's perfect for home/small office and small-medium businesses. ? [10 Ports Gigabit Network Switch]: The ethernet splitter has 8*1000M Ethernet port with auto-negotiation function + 2*1000M Uplink ports with Auto MDI/MDIX, all ports support wire-speed forwarding and the data rate is up to 1000Mbps (Note: It's not PoE Switch).
