Highlights 8 101001000 Mbps RJ45 ports With four Po E ports transfers data & power on one single cable Working with IEEE 8023af compliant PDs expands home & office network Requires no configuration & installation What This Product Does 8-Port Gigabit Desktop Switch with 4-Port Po E provides the seamless network connection It integrates 1000 Mbps Gigabit Ethernet & 10100 Mbps Fast Ethernet network capabilities How This Product Works 4 of the 8 Auto-Negotiation RJ45 ports (port-1 to port-4) of the switch support Power over Ethernet (Po E) function These Po E ports can automatically detect & supply power with those IEEE 8023af 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 Overload Arrangement TL-SG1008P has the priority function which will help protect the system when the system power is overloaded If all Po E PDs power consumption is > 53W a priority will be arranged among the Po E 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 & 4 are using 154w (maximum power per port is 154W) the system power is 462w in total (Po E max LED is red ) 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 154w & Port 3 will use 10w & no power will be supplied to Port 4 Easy To Use TL-SG1008P is easy to install & use It requires no configuration & installation With desktop design outstanding performance & quality the TP-LINK TL-SG1008P 8-Port Gigabit Desktop Switch with 4-Port Po E is a great selection for expanding your home or office network
