ADVANCED FEATURES:

High-Power PoE+ Delivery:

The Dell PowerSwitch N3248P-ON delivers a total PoE+ budget of 740W, providing reliable power to all 48 access ports simultaneously. This enables deployment of power-hungry devices such as IP phones, wireless access points, high-definition security cameras, video conferencing systems, and IoT endpoints without requiring additional PoE injectors. Its intelligent power management ensures that connected devices receive consistent and stable power even during peak network activity, reducing downtime and maintenance costs.

High-Bandwidth Connectivity:

Equipped with 48 × 1GbE RJ45 PoE+ ports and 4 × 10GbE SFP uplinks, the N3248P-ON supports a wide range of access and aggregation scenarios. This versatile port configuration allows for easy network expansion and high-speed uplinks to distribution or core layers. Additionally, the switch supports full-duplex communication at line rate, ensuring predictable performance for latency-sensitive applications like video streaming, cloud computing, and real-time analytics.

Open Networking and Programmability:

Built for open networking, the N3248P-ON is compatible with ONIE (Open Network Install Environment), allowing administrators to deploy third-party network operating systems such as Dell SmartFabric OS10, SONiC, and Cumulus Linux. This flexibility enables network teams to implement automation frameworks and programmability using REST APIs, Python SDKs, Ansible, Puppet, and Chef. Zero-Touch Provisioning (ZTP) further simplifies large-scale deployments, reducing manual configuration efforts and enabling network-as-code operations for consistent, repeatable configurations across campus networks.

Intelligent Traffic Management and QoS:

The switch features advanced traffic management capabilities, including deep packet buffers, eight egress queues per port, Weighted Random Early Detection (WRED), CoS-based scheduling, and Priority Flow Control (IEEE 802.1Qbb). These mechanisms ensure predictable performance and minimal latency for critical applications such as VoIP, video conferencing, cloud-based collaboration tools, and real-time analytics. Dynamic congestion management allows administrators to prioritize high-priority traffic while maintaining overall network efficiency.

Enhanced Security and Threat Prevention:

Comprehensive security features protect both the network and connected endpoints. The N3248P-ON supports Layer 2/3/4 ACLs, MAC-based dynamic and static port security, DHCP snooping, ARP inspection, IP Source Guard, and hardware-assisted DoS prevention. Secure boot and firmware integrity verification ensure that only trusted software runs on the device. Multi-tenant environments are supported with VRF-lite and Private VLANs, enabling network segmentation and traffic isolation for enterprise and campus deployments.

High Availability and Redundancy:

The N3248P-ON is designed for mission-critical deployments. Hot-swappable N+1 redundant fans and a modular 740W PoE+ PSU ensure continuous operation, even during maintenance or upgrades. Configurable airflow (Front-to-Back or Back-to-Front) provides flexibility for data center cooling optimization. Built-in health monitoring and predictive diagnostics allow administrators to proactively identify potential issues before they impact network performance, ensuring high reliability in demanding environments.

Advanced Monitoring, Analytics, and Telemetry:

The switch offers integrated monitoring and telemetry capabilities, including SNMPv1/v2c/v3, sFlow, RMON, Syslog, and streaming event logging. These tools provide real-time insight into traffic patterns, port utilization, power consumption, fan and temperature status, and environmental metrics. When combined with Dell SmartFabric OS10 automation features, administrators can implement predictive maintenance, optimize resource allocation, and maintain consistent performance across large-scale campus deployments.

Future-Ready Campus Networking:

Designed for modern enterprise and campus networks, the N3248P-ON supports converged networks, multi-tenant deployments, and high-bandwidth edge applications. With a combination of high-density 1GbE access, 10GbE uplinks, and a robust PoE+ budget, the switch is ideal for supporting next-generation applications such as AI/ML-enabled IoT devices, cloud services, high-definition video surveillance, unified communications, and smart campus infrastructure. Its open networking and programmable architecture ensure seamless integration into evolving campus topologies and long-term network scalability.

Energy-Efficient Design:

Optimized for reduced energy consumption, the switch incorporates energy-efficient PoE allocation and hot-swappable fans to ensure effective cooling while minimizing power usage. Dynamic power management helps lower operational costs and supports sustainable IT initiatives, making it suitable for environmentally-conscious enterprise environments.
