Overview of 20-Port Gigabit PoE Managed Industrial Ethernet Switch

                  CK7220MP series are 20-Port Full-gigabit Managed Industrial Ethernet switches. This series provide 1000M PoE port and 1000M SFP optical port, and the PoE power supply conforms to the protocol standard of IEEE802.3af/at. It adopt DIN-Rail or wall mounting, which can meet the requirements of different scenes.
                  Network management system supports various network protocols and industrial standards, such as STP/RSTP, 802.1Q VLAN, QoS, IGMP Static Multicast, Port Trunking, Port Mirroring, etc. This series also possesses complete management functions, including Port Configuration, Port Statistics, Access Control, Network Diagnosis, Rapid Configuration, Online Upgrading and so on, and supports CLI, WEB, Telnet, SNMP and other access methods. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.
                  CK7220MP series support two independent power supply circuits which can ensure the normal operation of the device when one power supply fails. When power supply or port has link failure, ALM indicator will be bright and send out alarm, meanwhile, alarm device connected to the relay will send out alarm for rapid scene troubleshooting. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. CK7220M series can be widely used in smart grid, rail transit, smart city, safety city, new energy, intelligent manufacturing and other industrial fields.
