Overview
LNK-204 Series PoE Switch is equipped with 4-port 10/100BASE-TX PoE and 2-port 100Base-T uplink. LNK-204 Series PoE switch can automatically detect and supply power with those IEEE 802.3af/at compliant Powered Devices (PDs). With DIP switch Extend mode to support 250 meters long distance transmission (Cat.6 cable). There is no need to worry about the damage of standard POE or Non-POE device, 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.
