| The SAPPHIRE SMS-4GE4S is a high-performance industrial Gigabit managed Ethernet switch engineered to support critical network infrastructures in severe industrial environments. Featuring 4 Gigabit copper ports and 4 Gigabit SFP fiber uplinks, this switch provides flexible connectivity for machines, servers, controllers, and remote segments over fiber — enabling extended reach and superior bandwidth across demanding installations.
Built with a rugged IP30 metal housing, the SMS-4GE4S offers strong resistance to electromagnetic interference, electrical surges, and other disturbances common in factory floors, transportation hubs, and utility environments. Dual power inputs and wide operating temperature tolerance ensure continuous performance where standard commercial switches fall short. Advanced Layer-2 and Layer-4 features such as VLAN (802.1Q & Q-in-Q), dynamic link aggregation, IGMP/MLD snooping, bandwidth control, and QoS traffic prioritization help optimize traffic flows and safeguard vital data streams. Redundant ring support (ERPS/MSTP) and rapid self-recovery capabilities enhance uptime in critical network topologies by minimizing disruptions in ring or mesh layouts. Security is enforced with support for IPv4/IPv6 protocol handling and secure management options including Web, Telnet, and SNMP interfaces. The SMS-4GE4S also supports secure remote management via SSH and SSL, simplifying configuration and monitoring across distributed networks. Ideal for industrial automation systems, large-scale surveillance networks, smart transportation systems, and building automation, the SMS-4GE4S delivers strong performance, flexibility, and reliability for mission-critical Ethernet infrastructure deployments |
