INDUSTRIAL GIGABIT MANAGED SWITCH SERIES

All models integrate 6kV lightning immunity, PSE short-circuit protection and EMC Class 4 surge/ESD resistance. The rugged fan less metal housing supports stable operation from –40°C to 85°C, delivering long-term reliability in harsh industrial environ- ments. This design minimizes downtime and maintenance requirements, making the switch ideal for industrial, outdoor, and mission-critical deployments.

The switch offers flexible segmentation through 802.1Q, MAC-based, and IP-based VLANs. It features a high-performance QoS engine with 8 queues using 802.1P, DSCP, and SP/WRR/WFQ scheduling. L2–L4 ACLs enable granular packet control, and full multicast support with IGMP v1/v2/v3, MLD Snooping, fast-leave, querier functionality, and IPv4/IPv6 multicast ensures smooth HD video and optimized bandwidth utilization. These capabilities provide deterministic performance for voice, video, and data traffic across enterprise and service-provider networks.

The system supports IEEE 802.1x, Radius, and Tacacs+ authentication for strong access control. Additional protection includes VLAN port isolation, DHCP Snooping, ARP guard, IP–MAC–Port binding, IP source guard, DoS protection, and loop detection. Access policies can be enforced by port, IP address, or MAC address to maintain strict network security. This multi-layered se- curity architecture protects against unauthorized access and internal or external network threats.

The switch supports STP, RSTP, and MSTP for stable loop-free operation and multi-path redundancy. Additional mechanisms such as loop guard, root guard, TC guard, BPDU guard, BPDU filter, and alarm relay outputs for power failures, port disconnec- tions, and abnormalities ensure uninterrupted operation with strong anti-interference capability. This comprehensive redund- ancy framework ensures continuous service availability in complex and highly dynamic network topologies.
