FS S5850-48B8C is a high-performance Layer 3 switch for modern data centers and high-bandwidth campus networks. It suits data center leaf deployments, campus core/aggregation layers, and service provider edges. It offers 48x 10G/25G SFP28 ports and 8x 40G/100G QSFP28 uplinks (breakout to 4x 10G/25G), delivering up to 4 Tbps switching capacity and 2976 Mpps forwarding performance, providing a solid foundation for high-density connectivity and high-speed interconnection.
The switch supports stacking/MLAG, BGP, EVPN-VXLAN, MPLS, PTPv2, and LACP, enabling scalable Layer 2/3 architectures. Redundant hot-swappable power supplies, smart fans, and dual-flash chips enhance reliability and performance. Flexible port speeds allow smooth migration from 10GbE to 25GbE access and uplinks from 10/40GbE to 100GbE, providing ample bandwidth for future expansion.
