Using DIP switch, the working mode of DES-Fl 016P-E can be changed. Network interface:lOBASE-T or lO0BASE-TX,1000 BASE-T Ethernet RJ-45 port• IEEE802.3ab 1000 BASE-T• IEEE802.3z 1000 BASE-X• IEEE802.3x Flow Control• IEEE 802.3af/at standard• LINK/ACT, POE1. Extend Mode: 1-8 ports support 250 meters long distance power supply (should be use catSe or cat6 cable)2. VLAN Mode: Isolating ports 1-16 to each other can effectively suppress network storms and improve network performance.3. QoS Mode: Customize application priority to improve network sensitivity. For example, video priority, monitoring transmission is moresmooth4. Power Mode: Automatically detect the power receiving port, find the dead device, power off and restart the devices
