This industrial compact PoE Ethernet switch is designed for heavy-duty applications in harsh environments, offering 6 Gigabit Ethernet (GbE) RJ45 ports with 4 ports supporting IEEE 802.3at/af PoE+ (30W per port), and a total maximum PoE output power budget of 120W. It features two 100/1000Mbps SFP slots for fiber optic connections, enabling extended transmission distances. The fanless design ensures silent operation while maintaining high Mean Time Between Failures (MTBF) for reliability. This switch supports a wide operating temperature range and is equipped with redundant 48VDC power inputs (44~57VDC), making it suitable for use in industrial factory automation, data centers, intelligent transportation systems, and military or utility applications where environmental conditions exceed commercial product specifications. Additionally, the switch offers DIP switch options for configuring broadcast storm protection, SFP mode, and RJ45 settings, and supports both DIN rail and wall mounting for versatile installation.
