4 of the 8 Auto-Negotiation RJ45 ports (port-1 to port-4) of the switch support Power over Ethernet (PoE) function. These PoE ports can automatically detect and supply power with those IEEE 802.3af compliant Powered Devices (PDs). 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.
TL-SG1008P has the priority* function which will help protect the system when the system power is overloaded. If all PoE PDs power consumption is >= 55W, a priority will be arranged among the PoE ports, then the system will cut off the power of the lowest-priority port.
Port Priority Function
*Priority (port 1=port 2=port 3>port 4): This function will help protect the system if the system power becomes overloaded. For example, Port 1, 2 and 4 are using 15.4W (maximum power per port is 15.4W), the system power is 46.2W in total. If there is an additional PD inserted to Port 3 with 10W then the system will cut off Port 4 to protect the system, this means Port 1, 2 will use 15.4W, and Port3 will use 10W, and no power will be supplied to Port 4.
Easy To Use
TL-SG1008P is easy to install and use. It requires no configuration and installation. With desktop design, outstanding performance and quality, the TP-LINK TL-SG1008P 8-Port Gigabit Desktop Switch with 4-Port PoE is a great selection for expanding your home or office network.
