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.
✅ 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:
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
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
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
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
