Overview

24RJ45 PoE Switch

The LNK-DIMC2424MP Series represents an advanced L2+ managed industrial PoE+ switch, engineered to deliver high-density connectivity and intelligent network management for demanding applications. This hardened Ethernet switch integrates 24× 10/100/1000Base-T ports with full IEEE 802.3at PoE+ support, providing up to 30W per port to power a wide range of devices such as IP cameras, wireless access points, and VoIP phones. Complementing the copper interfaces are 4× 1000Base-X SFP fiber optic slots that support both single-mode and multi-mode transceivers, enabling flexible fiber backbone connections and long-distance network extension.

Designed for deployment in harsh environments, this 24RJ45 PoE switch features a robust metal housing with wide operating temperature tolerance and high immunity to vibration and electromagnetic interference. The advanced L2+ management capabilities facilitate VLAN, QoS, port aggregation, and network security configurations, allowing for precise traffic control and optimized performance across distributed network topologies. Ideal for smart city infrastructure, industrial automation networks, and large-scale security surveillance systems, this switch offers a reliable, scalable solution for modern industrial networking requirements where power delivery, data transmission, and environmental durability are equally critical.
