PixelPro GXi Series ZN1-V4FN3/FN4 Installation Guide APPENDIX (B): POWER OVER ETHERNET The Power over Ethernet (PoE) is designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet (PoE) standard. The IEEE 802.3af allows for two power options for Category 5 cables. The IEEE 802.3af-2003 standard allows up to 15.4 W of power to device. However, 12.95W is the available power, as some power gets lost in the cable. The updated IEEE 802.3at-2009 (PoE+) standard allows up to 25.5W (Max 34.2 W) of power to device. PoE has advantages over conventional power in such places where AC powers cannot be reached or is expensive to wire. Power Comparison The PoE Property supported by the device is 802.3af. Property Available Power Max. Power by PSE Max. Current Supported Cable 802.3af 12.95 W 15.40 W 350 mA Category 3 or higher 802.3at 25.50 W 34.20 W 600 mA Category 5 or higher i Note For proper activation of PoE, the Category 5 cable must be shorter than 100m and conform the PoE standard. i Note With non-Power Sourcing Equipment (non-PSE) When it is connected with non PSE, the power adaptor should be connected. With power adaptor Connecting both PSE and power adaptor does not do any harm to the product. Disconnecting PSE or power adaptor from device does not reboot the device as long as either one is connected to the device. 06-2014-B 27
