4 Port Fast Ethernet Unmanaged POE Switch Intelligent PoE Management. When the power supply exceeds the limit, PoE ports intelligently manage the power supply, which extends the switch lifetime. Up to 300 m Long Range PoE Transmission. The distance between IPCs and switch can reach maximum 300 meters. 4/8-Core Adaptive Power Supply with Less Power Loss. 8-core power supply reduces the power loss on cables. 6KV Surge Protection to Improve Reliability in Harsh Environment. The built-in surge protection device protects the switch from the sudden lightning surge in harsh environment. Design for Video Transmission. VIP port ensures important data transmission when network congestion occurs.
