The JetNet 3705 is equipped with 4 PoE injector switch ports, delivers up to 15.4 watts in each port, and one 10/100Base TX Up-link port forwarding data to the remote end. The JetNet 3705 conforms to IEEE 802.3af Power over Ethernet (PoE) standard. The Power over Ethernet technology can power up PoE enabled powered devices in full capability, e.g. IP surveillance camera, wireless Access Point, VoIP phone set, POS system, industrial sensors, controllers and security card reader. By connecting an external DC 48V power supply, JetNet 3705 is able to perform power and data transmission to send/ receive over the same UTP/STP cable in each of the four PoE ports. To meet the requirements of operating under harsh environment, JetNet 3705 uses a robust aluminum case, offers IP31 protection, and supports alarm relay output. The JetNet 3705 provides standard industrial terminal block for the power and alarm relay contact output to alarm any port malfunction or power failure. For the user's convenience, it also provides a DC jack for the traditional AC/DC power adapter. Korenix JetNet 3705 is an Industrial 4-port PoE injector Switch with one 10/100TX Up-link port. The PoE port provides 10/100Mbps Ethernet speed and is conformed to IEEE802.3af PSE standard with 15.4W full power forwarding ability. To meet requirements of Industrial application, JetNet 3705 equipped 2 power inputs and provides real-time relay alarm mechanism for the power or port event alert. To operate correctly in a harsh environment, JetNet 3705 adopts aluminum case with excellent heat radiation, and the self-diagnostic LED display including power, port link and PoE power status on the top of the switch for real time monitoring. The JetNet 3705 is compliant with IEEE802.3af standard plus over current and short current protections to avoid damaging other powered device.
