About the Dell PowerSwitch S5248F-ON
The Dell EMC PowerSwitch S5248F-ON is a high-density 1U top-of-rack switch providing 48 ports of 25GbE (SFP28) server connectivity and 8 ports of 100GbE (QSFP28) uplinks, delivering a total switching capacity of 2.56Tbps. It is based on the Broadcom Tomahawk 2 merchant silicon ASIC and is designed for leaf-layer deployment in spine-leaf data center fabric architectures, making it one of the most widely deployed ToR switches in enterprise data centers running VMware NSX, open-source SDN, or traditional VXLAN/EVPN fabrics.
The S5248F-ON ships with Dell's SmartFabric OS10 (based on Debian Linux), which supports full open networking principles including native Linux shell access, Python scripting, Ansible and Terraform automation modules, and REST/gRPC APIs. This makes it equally usable by network engineers preferring CLI-based provisioning and DevOps teams automating infrastructure as code. It also supports SONiC (Software for Open Networking in the Cloud) for organizations standardizing on the open-source Microsoft-originated NOS.
In hyperconverged and VMware NSX deployments, the S5248F-ON is SmartFabric-ready, enabling zero-touch provisioning where the switch fabric self-configures based on server connectivity detected—dramatically reducing deployment time for VxRail and PowerEdge MX environments. Its 2-port 100GbE management plane and out-of-band management port ensure the control plane remains isolated from data plane traffic.
Ideal for
- Leaf switch in enterprise spine-leaf VXLAN/EVPN fabric
- Top-of-rack 25GbE server connectivity for PowerEdge hosts
- VMware NSX underlay fabric switch with SmartFabric automation
- HCI (VxRail or Nutanix) cluster ToR switch
- 25GbE iSCSI or NVMe/TCP storage network switch
- Open networking / SONiC standardization in cloud-style data centers
