The Switch Your 25GbE Servers Are Waiting For
You upgraded your servers to 25GbE NICs six months ago. The NICs are installed. The SFP28 transceivers are in a drawer. The servers are still plugged into 10GbE because the switch budget was cut in the same meeting that approved the NICs. The Dell PowerSwitch S5248F-ON is the missing piece: a 48-port 25GbE switch with 8x 100GbE uplinks, running Dell OS10 Enterprise Edition, at a price point that fits in the same budget cycle as the NICs.

The OS10 Difference — Why It Matters for Automation
Dell OS10 is built on an unmodified Debian Linux kernel. Unlike proprietary switch OSes that lock you into a CLI or a limited REST API, OS10 allows you to install standard Linux packages directly on the switch. Run Python scripts on the switch CPU. Install Ansible, Salt, or Puppet agents natively. Pipe switch telemetry into your existing monitoring stack without an intermediate collector. For network teams that have adopted infrastructure-as-code for server management, OS10 brings the same paradigm to the switch — no separate network automation platform required.
S5248F-ON in a 3-Tier Data Center Architecture
| Layer | Role | Recommended Switch | Ports Used |
|---|---|---|---|
| Server Access / ToR | Connects 25GbE servers to fabric | S5248F-ON (this switch) | 48x 25GbE to servers, 8x 100GbE to spine |
| Spine / Leaf-Spine | Interconnects ToR switches | Dell S5232F-ON (32х 100ГбЕ) | 32х 100ГбЕ, connecting up to 16 S5248F-ON ToR switches |
| Border / DC Interconnect | Connects DC to WAN or second site | Dell S5296F-ON (96х 25GbE + 8х 100ГбЕ) | Dense 25GbE aggregation + 100GbE uplink |
Compatible Transceivers and Cables
25GbE ports accept SFP28 transceivers (SR 100m, LR 10km) or SFP28 passive DAC cables (1m-5m). 100GbE ports accept QSFP28 transceivers (SR4 100m, LR4 10km) or QSFP28 passive DAC cables (1m-5m). Dell-branded, Интел, Finisar, and FS.com optics all supported — Dell OS10 does not enforce vendor-locked transceivers.
