ADVANCED FEATURES:

High-Performance Switching Fabric:

The S5448F-ON is engineered with a robust Broadcom Trident 3 chipset, delivering 16 Tbps full-duplex switching capacity and line-rate forwarding on all ports. It ensures low latency (<1.135 µs) even under heavy multi-service workloads, making it ideal for high-performance leaf-spine, server-aggregation, and virtualized environments. The switch supports VXLAN, EVPN, and advanced L2/L3 routing, providing scalable, flexible, and automated network architectures that can evolve with enterprise and cloud data center demands.

Open Networking Flexibility:

With ONIE support, operators can perform zero-touch installation of Dell SmartFabric OS10 or SONiC, allowing complete network operating system flexibility. This enables organizations to adopt software-defined networking (SDN), implement automation workflows, and integrate multi-vendor environments. Programmable interfaces and REST APIs allow DevOps teams to implement network-as-code, while dual-image support ensures safe, non-disruptive upgrades.

High Availability & Resiliency:

Dual hot-swappable AC or DC power supplies combined with 6 hot-swappable, variable-speed fan modules provide N+1 redundancy for maximum uptime. Airflow can be configured front-to-back or back-to-front, offering deployment versatility across diverse data center designs. Hardware health monitoring ensures predictive replacement of components, while non-disruptive maintenance features minimize downtime during upgrades.

Automation, Programmability & Cloud Integration:

The switch supports a wide range of automation tools, including Python SDK, Ansible, Puppet, Chef, and REST APIs, allowing rapid provisioning and centralized management. Zero-Touch Provisioning (ZTP) enables bulk deployment of multiple switches with minimal manual intervention. It integrates seamlessly with cloud orchestration platforms like OpenStack, VMware NSX, and Kubernetes CNI, supporting agile and cloud-ready network operations.

Advanced Security & Compliance:

Security is comprehensive and multi-layered. The S5448F-ON supports 802.1X authentication, RADIUS/TACACS+, L2/L3/L4 ACLs, DHCP snooping, IP Source Guard, private VLANs, VRF-lite, and DoS protection. Secure management is provided via SSH, HTTPS, and role-based access control, while regulatory compliance with RoHS, WEEE, REACH, and ENERGY STAR ensures enterprise-grade safety and environmental standards.

Enhanced Monitoring & Telemetry:

Real-time telemetry, SNMP, sFlow, RMON, Syslog, and environmental sensors provide deep insight into network health. Administrators can proactively monitor port utilization, errors, and traffic patterns, predict failures, and optimize network performance. This visibility enables preventive maintenance and operational efficiency across campus and data center environments.

Scalability & Future-Ready Architecture:

Designed for modern and evolving enterprise networks, the S5448F-ON can scale seamlessly from traditional 10/25GbE networks to high-density 100GbE uplinks. Its flexible uplink design, VXLAN/EVPN support, and virtualization-ready architecture ensure that it can accommodate growing bandwidth demands and multi-tenant cloud deployments without disruption.

Energy Efficiency & Operational Optimization:

Intelligent power and fan management dynamically optimize consumption based on port activity, reducing operational costs. Advanced traffic shaping, congestion management, and deep packet buffering ensure predictable performance even under heavy east-west traffic in high-density deployments.
