Crs7120 series 16 + 4G network management rack type industrial Ethernet switch adopts high strength IP40 protective shell and industrial grade EMC design. It is a self-developed two-layer Ethernet switch. Provides management functions, which can be managed through web browser, CLI and SNMP. 16 fixed 10 / 100M adaptive Ethernet ports, 4 fixed 1000base modules (supporting single-mode and multi-mode) or 1000BASE-T module (supporting twisted pair transmission) are provided. Based on the industrial installation requirements, we provide 1U standard rack type installation mode. At the same time, it adopts fan free, low power consumption, industrial design, and the working temperature range of - 40 ~ 75 ℃ can meet the requirements of various industrial sites and provide convenient Ethernet communication solutions.
