The S5850-48B8C is a layer 3 switch with wire-speed 48x 10G/25G SFP28 and 8x 40G/100G QSFP28 (breakout to 4x 10G/25G) ports, delivering 4 Tbps switching capacity and 2976 Mpps forwarding rate. It features redundant hot-swappable power supplies, smart fans, and dual-flash chips for enhanced reliability and performance.
With support for MLAG, BGP EVPN VXLAN, PTP v2, MPLS, LACP, and more, the switch meets the scalability, security, and application needs of modern networks. It is ideal for next-generation core, aggregation, and dynamic data center environments, as well as medium to large campus deployments, with the flexibility of enterprise top-of-rack and service provider environments. Ideal for seamless migration from 10GbE to 25GbE or from 10GbE/40GbE uplinks to 100GbE.

The dual power supplies can be replaced without shutting down the system, and the variable-speed fans with front-to-back airflow automatically adjust fan speed to reduce power draw.
["MLAG delivers device-level link redundancy and load balancing by aggregating links across two switches, enhancing network performance, reliability, and service continuity."]
BC/TC/OC modes can be flexibly configured based on factors such as the scale of the network and the application scenario to meet the time accuracy requirements in different network environments.
EVPN VXLAN provides a scalable solution for interconnecting campuses, data centers, and public clouds, simplifying Layer 2/3 deployments and enhancing network operations.
MPLS enables small and medium-sized operators to create tunnels for their users, which helps build point-to-point connections and achieves intercommunication between user networks.
