The Cisco CBS350-24S-4G 24-Port SFP Gigabit Managed Network Switch is a powerful, enterprise-level Layer 3 switch crafted for organizations requiring secure, high-speed and dependable fiber connectivity. Equipped with 24 dedicated SFP Gigabit ports, this switch is perfect for fiber-intensive environments like campus networks, data centers, and densely packed wiring closets. Additionally, four extra Gigabit combo uplink ports (SFP/RJ45) allow for versatile backbone integration and smooth network expansion, accommodating both fiber and copper connections as your infrastructure grows. With an impressive 56 Gbps switching capacity and a forwarding rate of 41.66 Mpps, the CBS350-24S-4G guarantees non-blocking, wire-speed performance for critical applications and large data transfers. Features such as advanced Layer 2 and Layer 3 capabilities—including VLANs, static routing, link aggregation, and Quality of Service (QoS)—allow for detailed traffic management and secure network segmentation. The user-friendly web-based management interface and Cisco Business Dashboard facilitate the configuration, monitoring, and troubleshooting processes, making network management manageable for both IT experts and business users. The energy-efficient design, rack-mountable structure and Cisco’s limited lifetime warranty position this switch as a future-ready investment for any expanding business.
