Case Study

S5850-24S2Q, 24-Port Ethernet L3 Switch, 24 x 10Gb SFP+, with 2 x 40Gb QSFP+, Support MLAG

The S5850-24S2Q is a Layer 3 switch featuring wire-speed 24×10GbE SFP+ and 2×40GbE QSFP+ uplink ports in a compact 1U platform, delivering up to 640 Gbps switching capacity and 480 Mpps forwarding rate.
It includes redundant hot-swappable power supplies and smart fans for enhanced reliability. Supporting advanced Layer 2/3 features such as MLAG, BGP, OSPF, LACP, and MACsec, the switch addresses the scalability, security, and application demands of modern networks. It is ideal for high-bandwidth aggregation in enterprise campus distribution deployments. It also serves as a Top-of-Rack (ToR) switch in data centers, providing 10GbE server access and 40GbE spine uplinks.
