One-Click Intelligence, Simplified O&M | E-link China Launches Revolutionary DIP-Configured 8+4 Port Managed Industrial
2026-01-21
Redefining Industrial Network Usability: World's First Smart Switch with DIP One-Click VLAN/Ring/PoE Reset Launches 8-Port 802.3at PoE+, 4 Gigabit SFP Slots, USB-C Zero-Touch Management. Unique Physical Switches Enable One-Click Deployment of Complex Features. In industrial network deployment, cumbersome configuration processes, high technical barriers, and complex operations have long been major obstacles preventing SMEs and field engineers from quickly building intelligent networks. Traditional managed switches require CLI or Web interface configuration, which is unfriendly to non-expert users, while simple unmanaged switches cannot meet advanced needs like VLAN isolation or ring network redundancy. To this contradiction, E-link China officially launches the world's first smart industrial PoE switch with integrated DIP physical switches. This L2+ 8+4 port managed switch makes deploying complex network features as simple as flipping a switch through its innovative 4-in-1 DIP switches, truly achieving "professional features, foolproof operation."                                                       Four Revolutionary Innovations 1. World's First DIP One-Click Configuration System One-Click VLAN Isolation: Flip a switch to divide the 8 copper ports into separate broadcast domains—no login to any management interface required. One-Click Ring Protection: Instantly enable RSTP/MSTP ring protocols to build self-healing network topologies. One-Click PoE Reset: Remotely reset Powered Devices (PDs) to troubleshoot cameras, APs, etc. One-Click 250m Mode: Break the 100-meter limit to support long-distance PoE powering (with high-quality cables). 2. USB-C Zero-Touch Management Revolution Farewell to RS232 Serial Ports: Use a standard USB-C port to connect directly to a computer/phone for advanced configuration. 3-Minute Rapid Deployment: Reduces initial configuration time from 30+ minutes to under 3 minutes. Mobile-Friendly: Manage the device via a phone's OTG port—field maintenance has never been this convenient. 3. Industrial-Grade Intelligent Power Architecture All 8x 10/100/1000BASE-T ports support IEEE 802.3af/at standards. 30W per port, with a maximum total PoE budget of 240W. Smart Power Management: Supports priority-based power delivery, scheduling, and consumption monitoring. 4. Full Gigabit High-Performance Switching 4x 1000BASE-X SFP slots support single-mode/multi-mode modules, with transmission up to 120km. Supports 9K Jumbo Frames, improving video surveillance data throughput efficiency by 35%. IEEE 802.3az Energy Efficient Ethernet reduces idle power consumption by 50%. Key Technical Specifications Switching Capacity: 24Gbps Packet Forwarding Rate: 17.8 Mpps MAC Address Table: 8K entries PoE Standards: IEEE 802.3af/at Fiber Ports: 4x 1000BASE-X SFP (LC) Management: Web/CLI/SNMP/DIP Switches/USB-C Operating Temperature: -40°C to 80°C Protection Rating: IP40 Aluminum Alloy Case Installation: DIN-Rail / Wall Mount Power Input: 48-57VDC, Redundant support (optional)
