TNC-PS4306N4 POE Powered Switch supports the IEEE802.3af/at power over Ethernet standard with a power distance of 100 meters and only powers 802.3af/at terminal devices, so there is no need to worry about compromising proprietary standards for POE or non-POE devices. In addition, the POE device stops supplying power when it is not connected. These devices, which are far from the power outlet, are suitable for hanging on the wall or on the ceiling, and the POE eliminates the need to connect the power outlets for these devices, making the connection to equipment that is difficult to connect to AC power more flexible and with minimal installation costs. This series POE Powered switches are ideal selection for small business networks that want to use the economic deployment of wireless access points (AP) and IP-based network surveillance cameras .
