The JetNet 3705 equips with 4 PoE ports, with each port delivering power up to 15.4 watts in maximum, and one 10/100Base TX Up-link port transfering 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, security sensors, controllers and card readers.
The JetNet3705 provides standard industrial terminal block for the power and relay alarm contact output to alarm any port break or power failure. For the user’s convenience, it also provides a DC jack for the traditional AC/DC power adapter. The JetNet3705 PoE ports provide PoE auto detection of the link partner to deliver the exact power to the PD. If the link partner is not a PD or the link cable is short, or the device is broken, it will executes a series of standard procedures to avoid sending out a huge power to damage the linked device.
To successfully deliver reliable power, JetNet 3705 builds in strong protection againest abnormal working conditions including 2KV power surge protection from the power input and over-voltage protection to keep PoE output voltage in between DC 44 ~ 57V, 350mA over-load current and 450 mA short current protection. The JetNet3705 PoE function is fully in compliant with IEEE 802.3af standard, therefore all PoE protection measures are put into practice in the JetNet3705 series.
