N1548 Use Case
Campus LAN Aggregation with N1548-Dell Networking N1548, 48×1GbE + 4×10GbE SFP+, Stack, Front-to-Back Airflow, AC
In a university campus deployment, IT teams deploy the N1548-Dell Networking N1548, 48×1GbE + 4×10GbE SFP+ Fixed port switch in stacked pairs to aggregate dozens of wireless access points and classroom switches. Its 10GbE uplinks carry high-bandwidth research traffic to the core, while front-to-back airflow aligns with data-center cooling. Outcome: Simplified VLAN segmentation, 40 Gbps of redundant uplink bandwidth, and predictable thermal performance that meets education’s 24×7 uptime SLAs.
Scalable Branch-Office Networking with N1548-Dell Networking N1548, 48×1GbE + 4×10GbE SFP+, Stack, Front-to-Back Airflow, AC
A national retail chain standardizes on the N1548-Dell Networking N1548 switch for each of its 150 branches. Using stackable modules, network operations teams preconfigure security VLANs, PoE-powered CCTV, and double-redundant 10GbE fiber backhauls. Front-to-back airflow supports cabinet cooling, and AC inputs simplify site power requirements. Outcome: Uniform policy enforcement, zero-touch provisioning across all sites, and 99.9% branch-network availability.
Data-Center Leaf Switch for Virtualized Servers with N1548-Dell Networking N1548, 48×1GbE + 4×10GbE SFP+, Stack, Front-to-Back Airflow, AC
In a virtualized private-cloud, the N1548-Dell Networking N1548 functions as a top-of-rack leaf switch, connecting 48 hypervisor hosts over 1 GbE and uplinking each rack to the spine at 4×10 GbE. Its modular stacking simplifies capacity growth, while IO-to-PSU airflow integrates seamlessly into hot-aisle/cold-aisle designs. Outcome: Consistent sub-millisecond latency, non-stop VM mobility, and 25% lower cooling costs through optimized airflow.
