TL-SG105PP-M2 is an unmanaged switch with 5 Gigabit ports that requires no configuration and provides 4 PoE (Power over Ethernet) ports. It can automatically detect and supply power with all IEEE 802.3af/at/bt compliant Powered Devices (PDs) at port 1-4. In this situation, the electrical power is transmitted along with data in one single cable allowing you to expand your network to where there are no power lines or outlets, where you wish to fix devices such as APs, IP Cameras or IP Phones, etc. The 2.5G ports support automatic negotiation to 10Mbps/100Mbps/1Gbps/2.5Gbps according to the type of connected device and provide sufficient bandwidth to unlock the highest performance of 2.5G/Multi-Gigabit devices, including NAS, a personal workstation, 8K video stream, and 2.5G Wi-Fi 6 AP
