Industrial 4-Port UPoE (60W) + 2 SFP Gigabit Switch with Redundant Power
Overview
LNK-GYH204GP-SFP is an industrial-grade Ethernet switch featuring 4 UPoE ports (60W per port), 2
Gigabit SFP uplinks, and 1 RJ45 port. With a rugged design, redundant power input, and -40°C~80°C
wide operating temperature, it ensures reliable high-power PoE supply for IP cameras, wireless APs,
and IoT devices in demanding environments such as transportation, mining, and energy.
Features
High Power PoE++: 4 Gigabit UPoE ports, each delivering up to 60W, total 240W output
Flexible Uplinks: 2 Gigabit SFP slots + 1 RJ45 uplink for seamless network expansion
Industrial Durability: Wide temp range (-40°C to 80°C), fanless metal housing
Reliable Power: Redundant DC inputs ensure continuous operation
Easy Deployment: DIN-Rail or wall-mount installation for versatile use
