The Longshine Switch LCS-GS8116-B is a 16-port Gigabit Ethernet network switch designed for use in retail and commercial networks. This unmanaged switch model features 16 RJ45 ports with 10/100/1000 Mbps, auto-negotiation, and auto MDI/MDI-X crossover functionality, allowing for seamless integration into existing network infrastructures without complex configuration. The compact metal housing measures 280 mm in width, 105 mm in depth, and 44 mm in height, weighing approximately 1.2 kg, making it ideal for space-restricted environments. The switch supports IEEE 802.3, 802.3u, and 802.3ab standards and provides reliable data transfer speeds of up to 1000 Mbps per port while maintaining backward compatibility with Fast Ethernet and Ethernet devices. Power consumption is optimized for efficiency, typically consuming less than 15 W under full load conditions. The robust metal construction ensures effective heat dissipation and electromagnetic shielding for stable operation in demanding commercial environments. Each port features individual LED status indicators for link/activity and speed for quick visual monitoring of the network connection. The store-and-forward switching architecture with a non-blocking switching capacity of 32 Gbps ensures minimal latency and reliable data transmission. With industry-tested components, the switch delivers consistent performance at operating temperatures from 0 °C to 40 °C and relative humidity of 10% to 90% non-condensing. The fanless design allows for quiet operation, making the device ideal for point-of-sale systems, office networks, and small to medium business applications where reliable connectivity and minimal maintenance are critical requirements.
