Power over Ethernet4 of the 8 Auto-tuning-RJ45 ports (port 1 to 4) of the switches support Power over Ethernet (PoE). This PoE ports PoE-compatible network devices automatically recognize and IEEE 802.3af powered devices (PDs) with electricity. The electrical current is transported together with the data via a single cable. In this way, you can expand your network easily and without any problem there, where no power cables or power outlets are present, but PoE-enabled devices such as access points, IP cameras or IP phones are to be operated.Behavior in case of overloadThe TL-SF1008P has a priority * function, which helps to protect the system when the system performance overstrained. As soon as the entire power consumption of the PoE-powered devices is greater than or equal to 57W, among the priorities assigned to PoE ports. The system will then decide on the power distribution and switches the power supply on port with the lowest priority.Port Priority FunctionPort Priority: This function is there to protect the system when the PoE power overstrained. Use the ports 1, 2 and 4, respectively, the maximum power output of 15.4 W per port, the total capacity is 46.2 W. There is also a additional powered device with 12 W on Port 3 is connected to the system, in order to avoid damage to the device port 4. This means that on port 1 and 2 respectively 15.4 W and on port 3 12W can be used. On Port 4 is not released.Easy to useThe TL-SF1008P, thanks to Plug&Play, easy to install. It does not require any configuration. With its compact desktop design and its performance performance is TP-LINKs TL-SF1008P a great choice for expansion of your home or office network.This text is machine translated.
