DATASHEET MANUAL REPORT CAD

The NSH-403P PoE Switch is a Layer 2 product that conforms to the IEEE 802.3af or IEEE 802.3at Power over Ethernet (PoE) standard. Data communication as well as power is provided via Ethernet cable to devices (PD) such as CCTV, WLAN APs and IP telephones that conform to the IEEE 802.3af / at standard. NST's PoE switches automatically detect the load on the connected device (PD) and dynamically supply the power required by that device.


The NSH-403P supports IEEE 802.3af international standard PoE, and its simple and cost-effective features enable flexible and efficient network configuration. The NSH-403GP provides four 10 / 100Mbps ports, including one uplink port and three PoE ports. NSH-403P is a high reliability product designed with safety and reliability first. The reset IC also provides a 100% chance of automatic recovery after a power failure and an electrical failure. NSH-403P is a product suitable for network CCTV and wireless LAN network configuration.
