N3048EP-ON Use Case
Enterprise Campus Edge Aggregation with High-Density PoE+
In a 1,200-user corporate campus, IT deploys the Dell Networking N3048EP-ON at each floor’s wiring closet to power 48 PoE+ IP phones, Wi-Fi 6 access points and security sensors. Leveraging its 740W PoE budget, L3 routing, QoS and stackable architecture, the solution delivers seamless VLAN segmentation, sub-second failover and centralized Open Networking OS management. Benefit: consolidated infrastructure, predictable performance under peak loads and simplified campus expansion without forklift upgrades.
Smart Retail Branch Networking with PoE-Powered POS and CCTV
A national retailer standardizes on the N3048EP-ON in 250 branch locations to power PoE+ POS terminals, digital signage and HD surveillance cameras over a single Cat6 cable. Dual 10GbE SFP+ uplinks aggregate traffic to the regional data center while L3 ACLs isolate point-of-sale VLANs from guest Wi-Fi. Benefit: reduced hardware footprint, secure multi-tenant segmentation and plug-and-play deployment that cuts branch rollout time by 40%.
High-Performance Top-of-Rack Switch in SMB Data Center
A mid-market service provider uses the N3048EP-ON as a Top-of-Rack switch to interconnect 40 virtualized application servers via 1GbE and two 10GbE SFP+ uplinks to the core spine. Its stacking capability ensures linear scaling to 384 ports with a single management plane, and built-in L3 routing accelerates east-west VM traffic. Benefit: low-latency switching, simplified VLAN routing at the rack level and a compact footprint that maximizes data-center rack density.
