SG300-52 Use Case
Redundant Fiber Uplink Aggregation for Branch Office Connectivity
In a mid-sized branch office, the Cisco SG300-52-50 10/100/1000 switch aggregates 52 end-user devices – desktops, VoIP phones and local file servers – over Gigabit Ethernet, while its 2 combo mini-GBIC ports provide redundant fiber uplinks to the corporate data center. Outcome: sub-5ms failover, elevated network uptime and simplified management via Cisco’s Web UI and CLI.
Top-of-Rack Virtualization Host Connectivity in SMB Data Center
Deployed as a top-of-rack switch in a small-to-medium data center, the Cisco SG300-52-50 supplies 52 Gigabit links to hypervisor clusters and storage arrays. The dual mini-GBIC ports establish 1Gbps fiber trunks to the core switch, ensuring low-latency connectivity for VDI and database workloads. Outcome: guaranteed 1 Gbps throughput per rack, optimized resource allocation, VLAN isolation and QoS for critical applications.
Campus-Wide VLAN Segmentation for IP Surveillance and Guest Wi-Fi
At an educational campus, the Cisco SG300-52-50 10/100/1000 switch supports up to 255 VLANs across its 52 copper ports to separate IP camera traffic and guest Wi-Fi. High-definition camera streams are uplinked via mini-GBIC fiber modules to the NVR cluster, while the wireless controller connects on a dedicated VLAN. Outcome: robust security boundaries, assured video bandwidth and centralized policy enforcement reducing operational overhead.
