Introduction JHA-MIGS28P is a high performance, cost-effective high-end managed industrial PoE switch. The switch provides 8 10/100/1000Base-T(X) PoE/PoE+ port and 2 1000Base-X SFP slot. Each port has a PoE function, especially for difficult to provide AC power and wiring costs demanding application scenarios, automatically adapt to IEEE 802.3af/at standard. The use of a Ring technology (network fault recovery <20ms) the user can easily set the redundant ring network to increase network reliability, it also support WEB, CLI, Telnet/serial console, Windows utility, and SNMP management of a variety of ways, rich QoS features for data traffic control and management, support ring protocol, RSTP and STP Ethernet redundancy support port-based VLAN, IEEE 802.1Q VLAN and GVRP protocol. The product also industrial design, and can be widely used in automotive PIS, CCTV, video surveillance systems, train control system, but also applies to any vibration shock, EMC compatibility requirements of harsh industrial applications, can meet a variety of industrial site requirements to achieve higher reliability.
