The GS-4210-48T4S 48-Port Managed Gigabit Switch provides 48 10/100/1000BASE-T Gigabit Ethernet RJ45 ports and 4 additional 100/1000BASE-X SFP slots. Boasting a high-performance switching architecture that is capable of providing the non-blocking switch fabric and wire-speed throughput as high as 104Gbps, which greatly simplifies the task of upgrading the LAN for increased bandwidth demands.
The Switch can be programmed for advanced management functions such as dynamic port link aggregation, which allows the operation of a high-speed trunk to be combined with multiple ports in achieving a 16Gbps fat pipe and supporting a fail-over feature as well.
