High-Density Branch Office Aggregation with J9728A-Aruba 2920-48G Switch
In a multi-department branch office requiring 48 Gigabit ports and dual 10GbE uplinks, the J9728A-Aruba 2920-48G Switch consolidates desktops, IP phones and printers onto a single, resilient Layer 3 platform. Its static routing and RIP support delivers sub-millisecond failover and 30% higher throughput, while Aruba’s intuitive management reduces configuration time by 40%, ensuring consistent SLA compliance and operational efficiency.
Campus Building Edge with Aruba VSF Stacking on J9728A-2920-48G
A university campus deploys two J9728A-Aruba 2920-48G Switches in a Virtual Switching Framework (VSF) stack to serve 96 classrooms and Wi-Fi access points. This architecture unifies control plane, automates VLAN segmentation for students and faculty, and scales capacity with zero-touch provisioning. The outcome: 50% faster network rollouts, seamless inter-VLAN routing, and simplified maintenance under a single IP-managed domain.
Secure Retail Network Segmentation Using J9728A-Aruba 2920-48G
A retail chain leverages the J9728A-Aruba 2920-48G Switch to isolate POS systems, guest Wi-Fi, and IP surveillance on dedicated VLANs. Advanced ACLs and static routing ensure PCI compliance and end-to-end encryption, minimizing breach surface. The result is a 60% reduction in unauthorized access attempts, centralized policy enforcement via Aruba ClearPass, and consistent customer experience across 200+ locations.
