| The SAPPHIRE SML-24GE4C is a robust and high-performance industrial Layer-2 managed Ethernet switch engineered for mission-critical network deployments in harsh environments. Equipped with 24 x 10/100/1000BASE-T RJ45 ports and 4 x 100/1000 SFP/RJ45 combo uplinks, this switch delivers flexible and scalable connectivity with both copper and fiber options, allowing seamless integration between local devices and long-distance uplinks. It supports comprehensive managed features such as VLAN segmentation (802.1Q), STP/RSTP/MSTP, ERPS redundant ring protocols, QoS traffic prioritization, and ACL security policies — empowering administrators with full control over traffic flows, security, and network topology optimization.
Built to withstand industrial rigors, the SML-24GE4C features a rugged IP40 aluminum enclosure, ensuring high immunity against electromagnetic interference and electrical surges common in factory floors and curbside traffic control cabinets. The switch accepts a wide input voltage range (AC and 48–57 VDC) for versatile power deployment and supports a wide operating temperature range from -40 °C to +80 °C, making it suitable for environments where temperature extremes are standard. Each unit undergoes a 100% burn-in test at 80 °C to guarantee quality and reliability in continuous operation. One of the key strengths of the SML-24GE4C is its redundant ring technology with rapid self-recovery capability, which significantly enhances network uptime in ring topologies. With advanced ERPS (Ethernet Ring Protection Switching) and Spanning Tree variations, the switch minimizes link downtime and helps maintain stable operations even during link failures — boosting resilience for critical services. The SML-24GE4C is ideal for industrial automation applications, intelligent transportation systems (ITS), video surveillance infrastructures, and tolling systems where high reliability, swift recovery, and secure traffic management are essential. Its flexible management options — including Web, CLI, and SNMP support — simplify configuration and monitoring within enterprise networks. With its combination of rugged design, feature-rich L2 management, and network resilience capabilities, this switch stands out as a dependable choice for modern industrial networks. |
