JG311A Use Case
Campus Network Aggregation with JG311A-HP HI 5500-24G-4SFP Switch
In a multi-building university campus, the JG311A-HP HI 5500-24G-4SFP acts as the distribution layer, aggregating 24 Gigabit access switches and uplinking via four 1 Gbps SFP ports or two 10 Gbps expansion slots. This configuration delivers low-latency connectivity for lecture halls, labs, and administrative offices, ensures seamless failover through resilient stacking, and simplifies network segmentation. Benefit: high-density port consolidation with scalable uplink capacity, resulting in optimized bandwidth utilization and reduced operational complexity.
IP Surveillance Backbone for Enterprise Security
In a corporate campus security deployment, the JG311A-HP HI 5500-24G-4SFP aggregates 200+ high-definition IP cameras over 24 Gigabit PoE-capable ports (or non-PoE with powered injectors) and transports video streams via four fiber SFP links to the central monitoring station. Advanced QoS prioritizes video traffic, while link-aggregation and redundant uplinks guarantee zero-frame-loss during peak hours. Benefit: end-to-end video integrity with dedicated bandwidth, enhanced failover resilience, and centralized VLAN management for segmented security zones.
SMB Data Center Core Switch in Virtualized Environments
For small and mid-sized data centers running server virtualization and storage networks, the JG311A-HP HI 5500-24G-4SFP serves as the core switch, interconnecting 24 1 Gbps hypervisor hosts and four 1 Gbps iSCSI storage links. Two expansion slots host 10 Gbps SFP+ modules for uplink to the WAN edge or disaster recovery site. Benefit: robust L2/L3 feature set with IPv4/IPv6 routing, dynamic link-aggregation, and energy-efficient design, delivering high throughput, simplified management, and predictable SLAs.
