The ONV-POE31004PLD is a smart PoE switch independently developed by ONV. It has 5*10/100Base-TX RJ45 ports. Port 1-4 can support IEEE 802.3 af/at PoE standard and single-port PoE power reaches 30W. Port 1-4 can support the PoE watchdog function. When the port communication failure corresponds to the port PoE will automatically restart, and self-recover network communication, reducing manual intervention and maintenance. As a PoE power supply device, it can automatically detect and recognize the power-receiving equipment that meets the standard and supply power through the network cable. It can supply power to PoE terminal equipment such as wireless AP, IP camera, VoIP, and visual intelligent building intercom through a network cable, and meet the network environment that needs a high-density PoE power supply. It is suitable for hotels, campuses, parks, banks, hospitals, factories, and small and medium-sized enterprises to form a cost-effective network. Unmanaged mode, plug, and play, no configuration, easy to use.
