SG300-28SFP Use Case
Data Center Access Aggregation with 1GbE and Fiber Uplinks
In a mid-sized enterprise data center, network engineers deploy the SG300-28SFP-26 (24×10/100/1000 RJ-45 + 2 combo mini-GBIC) as the top-of-rack access switch. They connect multiple server racks over copper and use the dual SFP ports for high-speed fiber uplinks to the core. Benefit: streamlined aggregation, 1 GbE port density, redundant fiber backhaul, simplified VLAN segmentation, and true gigabit throughput for virtualization and storage traffic.
Campus Building Distribution Over Fiber Backbone
A university IT team uses the SG300-28SFP-26 to distribute network services across a multi-building campus. They wire 20 labs and lecture halls via copper RJ-45 ports and leverage the two combo SFP ports for 1 Gbps fiber links between distant buildings. Benefit: extended reach up to 20 km, high-performance throughput, granular VLAN isolation per department, centralized management, and future-proof scalability.
IP Surveillance Backbone with Long-Distance Fiber Connectivity
A security integrator implements the SG300-28SFP-26 to support 4K IP cameras across an industrial complex. Local camera clusters connect via copper ports, while the mini-GBIC SFP ports link remote camera sites over single-mode fiber. Benefit: reliable PoE-ready infrastructure (with external injectors), minimal latency for video streams, secure VLAN segregation, and uninterrupted 24/7 monitoring over distances exceeding 10 km.
