This SAE-PE890-F PoE switch can prepare a field that power and data can feed from a single point, using Power over Ethernet (PoE) over a single cable. One 8 fast Ethernet ports and one uplink port prepare any 10/100 Mbps link and the rest of 8 ports can supply industry-standard IEEE 802.3af power for every POE standard devices. Regards to using advanced auto-sensing algorithm the SAE-PE890-F gives power only to IEEE802.3af front-end devices, so don't worry about connecting PoE or non-PoE devices to this feeder. Additionally, this good gives up the power when PoE devices are disconnected. Intelligently, SAE-PE890-F can recognized automatically PoE demands of devices, speed, duplex, and cable type using Auto Uplink™. Remarkably, It helps smart CCTV network designers to improve their planning and use the switch intelligently. SAE-PE890-F made by high quality of components were rigorous screened, have superior performance in stability, environmental adaptability. The product planned in a way of better resistance and ability to corrosion and electromagnetic interference. Power input also made a suitable and reliable types of power, to get more powerful suitability to environment.
