Dell PowerSwitch S5232F-ON vs Z9432F-ON
Dell PowerSwitch S5232F-ON (100GbE)
Dell PowerSwitch Z9432F-ON (400GbE)
The S5232F-ON and the Z9432F-ON are both 1U fixed Dell PowerSwitch platforms that run SmartFabric OS10, so the real decision is fabric speed and lifespan, not vendor. Choose the S5232F-ON when your spine or leaf standardizes on 100GbE and you want proven, cost-efficient density today. Choose the Z9432F-ON when you are building or future-proofing a 400GbE core for AI, HPC, or high-radix scale-out. Uniqcli configures and ships both, so the guidance below is about fit, not a forced winner.
Side by side
| Dell PowerSwitch S5232F-ON (100GbE) | Dell PowerSwitch Z9432F-ON (400GbE) | |
|---|---|---|
| Fabric tier | 100GbE spine and leaf. Thirty-two QSFP28 ports plus dual SFP+, built for classic 100G leaf-spine designs that dominate most enterprise and mid-size data centers. | 400GbE spine and aggregation. Thirty-two QSFP-DD ports, built for high-radix 400G cores and dense scale-out fabrics. |
| Interface and breakout | QSFP28 ports break out to 4x25GbE or 2x50GbE, so one switch can serve 100G uplinks and 25G server access from the same chassis. | QSFP-DD ports break out to 100G and 200G, letting a single 400G spine fan out to large counts of 100G leaf uplinks. |
| Throughput posture | High aggregate bandwidth sized for 100G fabrics. Ample for virtualized workloads, storage networks, and standard east-west traffic. | Substantially higher aggregate bandwidth per rack unit. Headroom for AI training clusters, GPU fabrics, and heavy east-west scale. |
| Best-fit workload | Enterprise virtualization, VDI, general-purpose storage and compute, and 100G leaf-spine refreshes where 400G is not yet justified. | AI and ML, HPC, disaggregated storage, and hyperscale-style fabrics where per-port bandwidth and radix drive the design. |
| Optics and cabling economics | Leans on mature, lower-cost 100G and 25G optics and DACs. Attractive when optics budget and existing cabling favor 100G. | Requires 400G-class optics and cabling. Higher per-port optic cost, offset by fewer switches and links at scale. |
| Scale and lifespan | A strong fit for right-now density. Excellent choice when your roadmap stays at 100G through this refresh cycle. | A future-proofing play. Protects the core when traffic is doubling and you want to avoid a mid-cycle spine rip-and-replace. |
| Software and operations | SmartFabric OS10 with a consistent CLI, automation, and open networking foundation. Fits existing Dell fabric tooling. | Identical SmartFabric OS10 experience, so operations, scripts, and staff skills carry straight over from 100G to 400G. |
| Power and thermal | Lower power draw and thermal load per switch, easing deployment in mixed or space-constrained racks. | Higher power and cooling demand that comes with 400G density. Plan rack power and airflow accordingly. |
| Federal and TAA | Available in TAA-compliant configurations for GSA, NASA SEWP V, and GPC buys through Uniqcli. | Same TAA-compliant path for federal 400G core builds, quotable on the same contract vehicles through Uniqcli. |

Choose Dell PowerSwitch S5232F-ON (100GbE) when...
Your fabric standardizes on 100GbE and you want proven density at a lower entry cost. It is the right call for enterprise virtualization, storage networks, and 100G leaf-spine refreshes where 400G is not yet justified. You get mature, affordable 100G and 25G optics, lighter power and thermal load, and full SmartFabric OS10 management. If your roadmap stays at 100G through this refresh cycle, the S5232F-ON delivers the density you need without paying for headroom you will not use. Drop your port counts into /bom and we will size the fabric on /quote.
Choose Dell PowerSwitch Z9432F-ON (400GbE) when...
You are building or future-proofing a 400GbE core for AI, HPC, GPU fabrics, or hyperscale-style scale-out. Its high-radix 400G ports break out to large counts of 100G leaf uplinks, so one spine can consolidate what used to take several. It runs the same SmartFabric OS10, so your operations and automation carry straight over. Choose it when traffic is doubling and you want to avoid a mid-cycle spine replacement, and plan for 400G optics plus added rack power and cooling. Send your growth targets to /quote and we will model the spine on /bom.
Neither switch is the default winner. The S5232F-ON is the pragmatic 100G workhorse for the fabrics most organizations run today, and the Z9432F-ON is the 400G spine for teams whose bandwidth curve is bending up fast. Many customers run both, with S5232F-ON at the leaf and 100G spine tiers while a Z9432F-ON core carries the 400G backbone. The deciding factors are your target port speed, your optics and power budget, and how long this fabric has to last. Uniqcli sells and supports both, and we will scope the right mix. Bring your topology to /quote or start a build on /bom, and we will map it to the correct PowerSwitch models.
Talk to a specialistFrequently asked
Can the S5232F-ON and Z9432F-ON work in the same fabric?
Yes. A common design uses S5232F-ON switches at the leaf and 100G spine tiers with the Z9432F-ON as the 400G core or aggregation layer. Because both run SmartFabric OS10, they share management and automation. Send your topology to /quote and we will map the tiers.
Is the Z9432F-ON overkill for a standard enterprise data center?
Often, yes. If your workloads are virtualization, VDI, and general storage that live comfortably on 100G, the S5232F-ON gives you the density at lower cost and power. Reserve the Z9432F-ON for AI, HPC, or fabrics that are outgrowing 100G.
Do I need new optics and cabling to move to the Z9432F-ON?
Plan for 400G-class optics and cabling on the 400G ports, though breakout lets you connect existing 100G leaf uplinks. The S5232F-ON reuses mature 100G and 25G optics and DACs. We will include the right optics and DACs in your /bom so nothing is missed.
Are both switches TAA-compliant for federal purchases?
Both are available in TAA-compliant configurations and quotable through Uniqcli on GSA, NASA SEWP V, and GPC. Whether you need a 100G refresh or a 400G core, we can put it on the right vehicle. Start on /quote.
Which one is more cost-effective?
It depends on scale. For 100G fabrics the S5232F-ON usually wins on upfront switch and optics cost. At high bandwidth, the Z9432F-ON can lower total cost by collapsing many 100G links into fewer 400G ports and switches. Share your port counts on /bom and we will run both scenarios.
