CRS7228P series are 28-port Gigabit layer 2 managed industrial Ethernet switch. It provides Gigabit PoE ports and Gigabit SFP slots, 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.It adopts 1U rack mounting, abundant numbers of interfaces and Gigabit bandwidth to meet the application requirements of large-scale industrial network.
Network management system supports various network protocols and industrial standards, such as STP/RSTP/MSTP, 802.1Q VLAN, QoS, IGMP Static Multicast, Port Trunking, Port Mirroring, etc. It 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.
This series support optional dual AC/DC power supply. The input power supply is 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, ALARM 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. It can be widely used in smart grid, rail transit, smart city, safety city, new energy, intelligent manufacturing and other industrial fields.
