1. [8-Port Gigabit Ethernet Switch] Features 8 x 10/100/1000 Mbps RJ45 ports, eliminating the need for dedicated uplink ports – any port can function as an uplink. Each port operates independently, so a failure won't affect others. Equipped with a high-speed network IC for faster and more efficient network performance. 2. [Plug and Play] Simple setup with no software installation or configuration required. Each port supports MDI/MDIX auto-negotiation and duplexing for effortless connectivity. IEEE 802.3X flow control ensures reliable data transfer. 3. [4KV Surge Protection] This Ethernet switch is designed with surge protection to withstand over 4KV of lightning, preventing circuit damage. Built-in protection circuits automatically secure ports against short circuits or overloads for safe and reliable operation. 4. [Portable Design] Compact size (only 5x2x0.8 inches) makes this Gigabit Ethernet splitter easy to carry for travel, business trips, or as a backup. Ideal for schools, homes, small to medium-sized businesses, micro-surveillance, laptops, game consoles, printers, and more. 5. [Energy Saving] This network switch can save up to 70% of power consumption by automatically adjusting power based on link status and cable length, reducing energy waste and overall heat generation. The fanless design ensures silent operation.
