N1148T-ON Use Case
University Campus Distribution with Dell N1148T-ON
Scenario: A mid-sized university deploys the Dell Networking N1148T-ON, a Layer 2 switch with 48 1GbE RJ45 ports and 4 SFP+ 10GbE uplinks, as a distribution layer to connect classrooms, research labs, VoIP phones, and Wi-Fi access points. VLAN segmentation separates student, faculty, and guest networks while high-speed uplinks aggregate traffic to the core. Outcome: Streamlined network management, high-bandwidth connectivity for data-intensive research, and scalable infrastructure for future device growth.
SMB Data Center Top-of-Rack Aggregation
Scenario: A small enterprise data center uses the Dell Networking N1148T-ON at top-of-rack to aggregate 48 1GbE server connections and four 10GbE SFP+ uplinks to the core. The switch’s non-blocking Layer 2 architecture delivers wire-speed performance for virtualized workloads and high-density storage clusters. Outcome: Optimized east-west traffic, reduced latency, predictable throughput for mission-critical applications, and simplified scaling for additional servers.
Branch Office Secure Multi-VLAN Networking
Scenario: A retail branch office implements the Dell Networking N1148T-ON, offering 48 RJ45 1GbE ports and 4 SFP+ 10GbE uplinks, to serve POS terminals, IP cameras, VoIP phones, and guest Wi-Fi. Robust VLAN segmentation enforces PCI-DSS compliance for payment systems, isolates voice and video traffic, and secures public Internet access. Outcome: Enhanced security posture, reliable voice/video quality, unified switch management, and minimal operational overhead.
