| The SAPPHIRE SMS-16GE4S is a high-performance, industrial-grade 20-port managed Gigabit Ethernet switch engineered to support resilient and secure network infrastructures in heavy-duty environments. Featuring 16 x 10/100/1000BASE-T RJ45 ports and 4 x 100/1000BASE-X SFP fiber-optic interfaces, this switch provides high-speed connectivity with flexible uplink options, enabling seamless integration into both copper and fiber segments of your network.
Built for challenging industrial environments, the SMS-16GE4S comes in a rugged IP30-rated metal enclosure that offers excellent protection against electromagnetic interference and electrical surges commonly found on factory floors and outdoor cabinets. With redundant power input support (12–48V DC) and wide temperature operation (-10°C to 65°C standard, extended to -40°C to 75°C), it delivers reliable performance where standard commercial switches fail. This switch supports advanced redundant ring technologies including ERPS (Ethernet Ring Protection Switching) and MSTP (Multiple Spanning Tree Protocol), enabling ultrafast network recovery (as low as 50ms) to minimize downtime in critical industrial applications. Its robust Layer-2 and Layer-4 feature set includes VLAN (802.1Q & Q-in-Q), dynamic link aggregation, IGMP snooping, QoS traffic management, broadcast/multicast storm control, and comprehensive ACL capabilities — ensuring optimal performance for voice, video, and data traffic across complex network topologies. Security is reinforced with enhanced features like IPv4/IPv6 access control lists, preventing unauthorized data flows and allowing granular policy enforcement at the network edge. Flexible management is provided through Web GUI, Telnet, and SNMP interfaces, with support for secure remote management protocols such as SSH, SSL, and SNMPv3. The dual-speed SFP interfaces support both 100BASE-FX and 1000BASE-SX/LX SFP modules, enabling administrators to choose the ideal transceiver for specific distance and speed requirements, from short fiber runs to long-haul backbones. Whether deployed in industrial automation, transportation systems, large-scale surveillance, or enterprise network expansions, the SMS-16GE4S combines performance, reliability, and flexibility to ensure seamless, high-availability Ethernet connectivity |
