This is an unmanaged eight-port RJ-45 Ethernet 10/100/1000 Mbps switch. RJ45 auto-adaptive ports, each port has MDI/MDIX automatic cross-detection function. The use of store and forward technology, combined with dynamic memory allocation, ensures that the bandwidth is effectively allocated to each port. Using green Ethernet technology (IEEE802.3az), the energy consumption at both ends of the network connection can be reduced when the switch is in an idle state. Now you have a cost-effective solution to your network upgrade needs. With our certification test program, we can guarantee your product will work right the first time.
