【Introduction】
28-Port Managed Gigabit Ethernet Switch, black iron shell design, built-in DC 12V Power supply, light and simple, with LED indicator on the panel, can dynamically display the connection and operation of equipment, provide simple fault detection methods, and facilitate maintenance and management; this series of switches provide advanced network management functions: redundant ring network, VLAN, cluster, QoS, speed control, port image, fault alarm and firmware online upgrade.
The adaptive port can automatically adapt to the 10m, 100m and 1000m networks, and can automatically adapt to the full duplex or half duplex mode; the MAC address self-learning function ensures error free data transmission; the store and forward mode prevents the damaged packets from flooding in the network; the flow control function can prevent the impact of a large amount of instantaneous data on the network; the port supports MDI/ Mdix auto flip function, non-blocking line speed transmission of all ports.
It is mainly located in the core or convergence layer of user networks such as industrial parks, buildings, factories and mines, government agencies, community broadband, etc.; it can be widely used in Ethernet access scenarios such as small and medium-sized enterprises, Internet cafes, hotels, schools, etc.
【Application Environment】
