Dell PowerSwitch S5248F-ON 48x25G + 4x100G Switch

The Dell PowerSwitch S5248F-ON is a high-density, open-networking top-of-rack switch designed for modern disaggregated data center architectures. Built on a merchant silicon platform, it delivers 48 ports of 25GbE SFP28 connectivity combined with 4 ports of 100GbE QSFP28 uplinks and 2 ports of 100GbE QSFP28 dedicated for stacking or additional uplinks, providing a full 2.0 Tbps of non-blocking switching capacity. The S5248F-ON supports the Open Network Install Environment (ONIE) standard, enabling operators to load their preferred network operating system — including Dell EMC SmartFabric OS10, Cumulus Linux, SONiC, and other ONIE-compatible NOS options — aligning with a software-disaggregated infrastructure strategy.

The switch is purpose-built for spine-leaf and Clos fabric topologies where 25G server access and 100G uplink density are critical. Its forwarding architecture supports Layer 2 and Layer 3 protocols including BGP, OSPF, IS-IS, ECMP, and VXLAN with BGP-EVPN for scalable overlay networking. Hardware-based VXLAN routing and bridging capabilities make it well suited for multi-tenant cloud environments and large-scale virtualized workloads. The platform also supports robust Quality of Service (QoS) features, precision time protocol (PTP/IEEE 1588), and extensive telemetry capabilities including streaming telemetry for real-time network visibility.

As a 1U form-factor switch with front-to-rear and rear-to-front airflow options and redundant hot-swappable power supplies, the S5248F-ON is optimized for high-availability deployment in enterprise core data centers, colocation facilities, and hyperscale-adjacent environments. Its open, standards-based design reduces vendor lock-in and enables integration with modern automation frameworks such as Ansible, Puppet, Chef, and REST APIs, making it a natural fit for DevOps-driven network operations and zero-touch provisioning workflows.

Ideal for

• 25G server access layer in spine-leaf data center fabrics requiring high port density and low-latency east-west traffic forwarding
• Disaggregated open-networking deployments where operators run third-party or open-source NOS such as SONiC or Cumulus Linux on white-box-compatible hardware
• Multi-tenant cloud and virtualized environments leveraging VXLAN with BGP-EVPN for scalable Layer 2 overlay and network segmentation across distributed racks
• High-performance computing and AI/ML cluster interconnects demanding consistent low-latency, non-blocking 25G server-to-server bandwidth with 100G uplinks to aggregation or spine layers
• Automated, software-defined data center operations utilizing zero-touch provisioning, streaming telemetry, and REST API or Ansible-based configuration management for rapid rack deployment
• Colocation and edge data center environments requiring a compact 1U footprint, redundant power supply options, and flexible airflow configurations to meet varied facility constraints
