Compliance with the 802.3af/at PoE+ standard supports up to 30 W on each PoE port. The total 64 W PoE power budget* for the 4× PoE ports opens up a wide range of applications, such as surveillance for offices, dormitories, and small businesses. It is fully compatible with IP cameras, access points, IP phones, computers, printers, and more.When total power consumption exceeds 64 W, the intelligent power management will cut the lower priority port power. This ensures the high priority port’s power supply and protects the device from power overload. It also automatically detects and provides the required power for your PoE devices while protecting your PoE and non-PoE equipment from being damaged.Administrators can designate the priority of traffic based on QoS, for example, to ensure that voice and video applications remain clear and lag-free.GMP Snooping optimizes multimedia traffic delivery, to ensure a better network experience,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.  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.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.
