Industrial 28G Layer 2+ Full Gigabit PoE Managed Ethernet switch

The RP428 is an industrial-grade rackmount 28G switch with 24 Giga PoE+ ports, each can output 30W. The 4 Giga combo ports and 4x100M/1G fiber SFP ports can configure max. 8 fiber Giga ports for more field switches with long-distance fiber connections. Standard redundancy mechanisms are designed with enhancement such as ITU-T G.8032 Ethernet Ring Protection Switching (ERPS) and ERPSv2 Plus, RSTP, and enhanced RSTP. Many High-level cybersecurity protocols are implemented such as DHCP Snooping, IP Source Guard, Dynamic ARP Inspection. Rugged design and high EMC immunity make RP428 an ideal solution for industrial Critical Surveillance applications.
