The IGS-6325-20T4C4X is a high-performance industrial Layer 3 managed Ethernet switch engineered for demanding environments such as data centers, service providers, telecom, and industrial automation. It delivers 20 10/100/1000BASE-T copper ports alongside 4 gigabit TP/SFP combo slots and 4 10G SFP+ uplink ports, enabling flexible high-speed connectivity and long-distance fiber transmission up to 10 kilometers. Designed with advanced redundancy and fault tolerance, this switch features dual 100-240V AC or 36-60V DC power inputs with active-active redundant power failure protection and polarity reverse protection for maximum uptime. Housed in a rugged IP30 metal case with an extended operating temperature range of -40°C to 75°C, it withstands harsh industrial conditions and offers comprehensive EFT and ESD protection. The device supports rich Layer 3 IP routing protocols including OSPFv2, static routing, and per VLAN routing, alongside Layer 2 features such as VLAN Q-in-Q, private VLAN edge, spanning tree protocols, link aggregation, and Ethernet Ring Protection Switching (ERPS) for enhanced network resiliency. With extensive security measures including IEEE 802.1X authentication, ACLs, DHCP snooping, dynamic ARP inspection, and IP source guard, it protects against unauthorized access and network attacks. Management is seamless through dual-stack IPv4/IPv6 support, CLI, web interface, SNMP, and secure SSH/SSL. Integrated digital input/output ports facilitate sensor alarms and network alerts via email and SNMP traps, making the IGS-6325-20T4C4X a robust solution for mission-critical industrial networks requiring high bandwidth, reliability, and security.
