Description:	Equipped with a high performance switching engine, the 20-Port All-Gigabit Managed Switch performs optimally. It has low transmission delay, large buffer and is highly reliable. It also has a strong switching capability and optimizes transmission performance when accessing Ultra HD videos. With its full metal design and fanless design, the device has great heat dissipation and is low power consumption, working in environments ranging from ā€“10Ā°C to 55Ā°C (+14Ā°F to +131Ā°F). With protection against overvoltage, EMC and overcurrent from power input terminals, the switch effectively resists interference from static electricity, lightning, and pulses. It also has powerful network management functions, supporting IGMP Snooping, Link Aggregation, QoS, LLDP, STP/RSTP, Web. Link Aggregation Combines multiple physical links into one virtual channel for dynamic redundancy and load balancing, ensuring that the connection remains stable.
