CRS9228 series is 28-port Gigabit/10 Gigabit layer 3 industrial Ethernet switch. It provides Gigabit copper ports and Gigabit SFP slots. 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 a variety of network protocols and industry standards, such as ARP, RIP, OSPF, NAT, ERPS, STP/ RSTP/MSTP, 802.1Q VLAN, QoS function, IGMP Snooping static multicast function, port trunking, port mirror, etc. It has perfect management functions, supporting port configuration, port statistics, 802.1X authentication, network diagnosis, rapid configuration, online upgrade, loop detection, etc. CLI, WEB, Telnet, SSH, SNMP and other access methods can be supported. It can provide users with good experience with friendly design of network management system interface, simple and convenient operation.
This product supports 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.
