【Product Description】
28-port Gigabit Ethernet switch, with black iron shell design, built-in DC 12V power supply, light and convenient, with LED indicator on the panel, which can dynamically display the connection and operation of the device, providing a simple fault detection method for easy maintenance and management; This series of switches provides advanced network management functions: redundant ring network, VLAN, cluster, QOS, speed control, port mirroring, fault alarm, and firmware online upgrade.
The adaptive port can be automatically adapted in 10M, 100M, 1000M networks, and can automatically adapt to full-duplex or half-duplex mode; MAC address self-learning function to ensure error-free data transmission; store-and-forward mode to prevent damaged packets from being on the network Flooding in the middle; flow control function, which can prevent the influence of a large amount of instantaneous data on the network; the port supports MDI / MDIX automatic flip function, and all ports are non-blocking wire-speed transmission.
Mainly located in the core or aggregation layer of user networks such as industrial parks, buildings, factories and mines, government agencies, and residential broadband; it can be widely used in Ethernet access scenarios such as small and medium-sized enterprises, Internet cafes, hotels, and schools.
