In a distributed professional services firm, the SG300-28-26 delivers 26 copper Gigabit ports for workstations, two combo mini-GBIC uplinks to the headquarters data center, and hardware-based VLANs to isolate HR, finance and guest traffic. IT teams gain resilient, low-latency connectivity over fiber, simplified network segmentation and single-pane management, resulting in 99.99% uptime and streamlined compliance.
At a manufacturing plant deploying 100+ HD cameras, the SG300-28-26 aggregates each camera’s 10/100/1000 connection on its 26 RJ45 ports, then trunk-aggregates video streams over dual mini-GBIC fiber links to the NVR cluster. The result is non-blocking throughput, deterministic QoS for video, and long-reach resilience—enabling real-time monitoring and rapid forensic retrieval without packet loss.
A regional hotel chain uses the SG300-28-26 to connect 200 VoIP phones and 50 Wi-Fi APs on its copper ports, while leveraging combo mini-GBIC uplinks for redundant links to the core. Advanced QoS policies guarantee crystal-clear voice and prioritized guest Wi-Fi, reducing dropped calls by 95% and improving guest satisfaction scores—backed by centralized switch management and audit-ready security.
