Thank you for viewing. This is the TP-Link 8-Port Switching Hub TL-SG108. I purchased it at the end of last year and set it up, but I only used it once and then stored it away. I will send the main unit and the AC adapter. 10/100/1000Mbps, Gigabit, compact and robust metal casing, no configuration required. [Energy Saving] By introducing Green Ethernet technology, it is possible to save up to 84% of power consumption compared to existing models. [High Reliability] Achieves reliable data transfer based on IEEE 802.3X. [Metal Casing] Ideal for desktop installation or wall mounting. Please refer to the official website for details. https://www.tp-link.com/jp/home-networking/soho-switch/tl-sg108/
