DATASHEET MANUAL REPORT CAD

NHM-2208P is a high-performance industrial PoE switch that supports eight 10/100/1000Mbps PoE ports and two 1Gbps or 2.5Gbps SFP ports. NHM-2208P is designed to be suitable for areas that require high-speed and reliable network access, such as smart factories, CCTV in smart cities, and wireless LAN network construction. The international standard G.8032 ERPS Ethernet ring protection switching technology is applied, so if a problem occurs in the network, the ring can be quickly switched and the network can be restored to normal, and problems with terminals such as CCTV cameras and wireless LAN APs connected to the PoE port are possible. If there is, only the power to that port can be reset, allowing the problem to be quickly resolved remotely. Additionally, it supports operating temperatures from -40 degrees Celsius to +80 degrees Celsius, providing excellent performance even in harsh environments.
