SG250-50 Use Case
Enterprise-Grade Network Segmentation for SMB Offices
In a 50-employee law firm handling sensitive client data, the SG250-50 enables creation of up to 200 VLANs and Layer 3 static routes to isolate finance, HR and guest networks. By reducing broadcast traffic by 40% and enforcing granular ACL policies, it delivers enhanced security, predictable performance and compliance with data-protection regulations.
Unified Communications Optimization for VoIP & Video Conferencing
In a mid-sized call center managing 200 concurrent VoIP calls and video conferences, the SG250-50 applies IEEE 802.1p QoS and traffic prioritization to guarantee sub-30 ms latency and jitter under 5 ms. The result is crystal-clear voice quality, uninterrupted video streams and a 25% reduction in dropped calls.
High-Density Wi-Fi Backhaul Aggregation in Educational Campuses
On a university floor supporting 300+ students, the SG250-50 aggregates 48 gigabit connections from access points and two 10 Gbps SFP+ uplinks to the core network. This configuration boosts wireless throughput by 50%, eliminates congestion during peak lecture hours and ensures reliable connectivity for e-learning and IoT deployments.
