L2+ Industrial Managed PoE Switch 12-Port 1000T(8-port 802.3at PoE) 4x10G SFP+

Product Overview:

The LNK-GYM4012GP-SFP Industrial Managed Switch delivers high-performance networking with 8×802.3at PoE+ ports (30W/port), 4×10G SFP+ fiber uplinks, and L2+ management capabilities, designed for mission-critical industrial applications.

Key Features & Benefits

✅ High-Power PoE+ & 10G Fiber Connectivity

• 8×802.3at PoE+ Ports (30W each): Power Wi-Fi 6 APs, PTZ cameras, and industrial devices

• 4×10G SFP+ Slots: Enable ultra-fast fiber backhaul (10GBase-SR/LR/ER) for bandwidth-intensive networks

• Auto-Negotiation (10/100/1000M): Simplifies mixed-speed device integration

✅ Advanced Network Management (L2+)

• <20ms Self-Healing Redundancy (ERPS/RSTP/MSTP): Ensures uninterrupted operation in ring/mesh topologies

• VLAN, QoS & ACL Policies: Prioritizes critical traffic (VoIP, video, control data)

• Port Mirroring & Rate Limiting: Enables real-time monitoring & bandwidth control

✅ Industrial-Grade Reliability

• Fanless & Low-Power Design: Silent operation with enhanced durability

• Wide Temp Range (-40°C to 75°C): Operates in harsh outdoor/industrial environments

• 6KV Surge Protection (All Ports): Safeguards against lightning & power surges

✅ Flexible Management & Security

• Web/CLI/SNMP Management: Remote configuration via intuitive interfaces

• Broadcast Storm Suppression: Prevents network congestion in high-traffic deployments

• Lock Port Security: Restricts access to authorized MAC addresses

Product Features:

1. Advanced L2+ Network Management

• 802.1Q VLAN & Port Isolation: Secures network segmentation for OT/IT convergence

• IGMP Snooping v1/v2/v3: Optimizes multicast traffic for video surveillance & industrial streaming

• DHCP Snooping & IP Source Guard: Prevents unauthorized DHCP servers and IP spoofing attacks

• LLDP Discovery: Automatically maps network topology for simplified troubleshooting

2. High-Performance Connectivity

• 12×10/100/1000BASE-T Ports (8×802.3at PoE+): Deliver 30W/port to Wi-Fi 6 APs, PTZ cameras & industrial IoT

• 4×10G SFP+ Fiber Ports: Enable ultra-low-latency backbone links (up to 40km with single-mode)

• Jumbo Frames (9.6KB): Boosts throughput for 4K video & large data transfers

3. Carrier-Grade Reliability

• STP/RSTP (802.1D/W): Ensures <50ms failover in redundant ring/mesh topologies

• PoE+ Management: Monitors power usage & prioritization per port

• ACL & ARP Inspection: Enforces granular security policies against network threats

4. Flexible Administration

• Multi-Management Interfaces: Web, CLI, SNMPv3, SSH/Telnet for remote/on-site control

• Port Mirroring: Facilitates real-time traffic analysis without disruption

• Broadcast Storm Control: Automatically throttles excessive traffic to prevent network congestion

Application Scenarios

1. Smart City Infrastructure

• Powers Wi-Fi 6/6E mesh networks with 30W PoE+ ports for public hotspots

• Provides 10G fiber backhaul for traffic management systems with <50ms RSTP failover

2. Industrial Automation Networks

• Connects Industry 4.0 equipment via EtherNet/IP with QoS prioritization

• Supports deterministic communication (<1ms jitter) for motion control systems

• Delivers 8×30W PoE+ to machine vision cameras and AGV charging stations

3. Transportation Mission-Critical Systems

• Implements EN 50155-compliant networks for railway onboard communications

• Features -40°C to 75°C operation for tunnel surveillance deployments

• Provides IP source guard for cyber-secure signaling networks

4. Energy Sector Deployments

• Meets IEC 61850-3 standards for substation automation

• Enables 9.6KB jumbo frames for PMU data streaming in smart grids

• Supports LLDP for automatic topology discovery in distributed energy resources

5. High-Security Surveillance

• Powers 4K AI cameras with PoE+ budget management

• Facilitates port mirroring for forensic video analysis

• Implements 802.1X authentication for access control in restricted areas

Technical Superiority:

• Protocol-aware switching for industrial automation standards

• Deterministic performance with time-sensitive networking (TSN) readiness

• Conformal coated PCBs resist humidity and corrosive gases

• 5-year MTBF certification for mission-critical deployments
