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 metres. 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.
