LNK-104G Series PoE switch can automatically detect and supply power with those IEEE 802.3af compliant Powered Devices (PDs),it’s 4 10/100/1000Mbps Auto-Negotiation RJ45 ports with 4 PoE (Power over Ethernet) ports, the distance of power supply is 100 Meter. There is no need to worry about the damage of standard POE or Non-POE Devices, it will be power off when the POE Device is not connecting. In this situation, the electrical power is transmitted along with data in one single cable allowing you to expand your network where there are no power lines or outlets, where you wish to fix devices such as APs, IP Cameras or IP Phones, etc.
