Dell PowerSwitch N3200-ON vs S-series
Dell PowerSwitch N3200-ON
Dell PowerSwitch S-series
Both lines carry the Dell PowerSwitch name, but they solve different problems. The N3200-ON is a campus and office access/distribution family built around 1GbE and Multigigabit (1/2.5/5/10GbE) copper ports, optional PoE/PoE+ for powering phones, APs, and cameras, and 10GbE or 25GbE uplinks. The S-series (for example the S5200-ON models) is a data center top-of-rack and leaf/spine family built around 25GbE server connectivity and 100GbE fabric uplinks, with the lossless-Ethernet and airflow features data centers expect. Choosing between them is less about "better" and more about where the switch sits: wiring closet versus server rack. This page lays out the practical differences so a Uniqcli buyer can match the right line to the deployment.
Side by side
| Dell PowerSwitch N3200-ON | Dell PowerSwitch S-series | |
|---|---|---|
| Primary role | Campus / office access and Layer 3 distribution — wiring closets and floor switching for endpoints | Data center top-of-rack (ToR) and leaf/spine fabric — server and storage connectivity |
| Port profile | Up to 48 ports of 1GbE or Multigigabit 1/2.5/5/10GbE copper (RJ45), with 10GbE SFP+ or 25GbE SFP28 uplinks depending on model | High-density 25GbE SFP28 server ports (12/24/48/96-port models) with 100GbE QSFP28 fabric uplinks; 32-port 100GbE spine option |
| PoE | Yes — multiple PoE/PoE+ models for powering Wi-Fi APs, IP phones, and cameras at the edge | No — data center fabric switches connect powered servers/storage, so PoE is not part of the design |
| Operating system | Ships with Dell OS6 (campus-oriented); the -ON hardware is ONIE-based and also appears on the SmartFabric OS10 compatibility list | Runs Dell SmartFabric OS10 (Enterprise Edition); ONIE-based for open NOS options |
| Switching capacity | Up to roughly 1.56 Tbps full-duplex per switch — sized for campus edge/distribution traffic | Up to roughly 6.4 Tbps full-duplex per switch — sized for east-west data center traffic |
| High availability / scaling | Stacking architecture lets you manage up to 12 switches as one logical unit from a single IP; dual hot-swap PSUs on many models | Leaf/spine scale-out with VLT/fabric features; redundant hot-swap PSUs and fans, non-blocking design |
| Data center features | Standard campus L2/L3; not built around DCB lossless Ethernet | Priority Flow Control (PFC), ETS, and DCBX for lossless / RoCE storage and converged DCB environments |
| Airflow | Front-to-back airflow suited to wiring-closet placement | Reversible airflow (I/O-to-PSU or PSU-to-I/O) for hot-aisle / cold-aisle data center containment |

Dell PowerSwitch N3200-ON
Dell PowerSwitch S-series
Choose the N3200-ON for campus and office edge
Pick the N3200-ON when you are wiring floors, classrooms, or offices and need to connect laptops, phones, APs, and cameras. Its strengths are the things campuses actually require: dense 1GbE and Multigigabit copper, PoE/PoE+ budget to power devices over the same cable, simple stacking to manage a closet as one unit, and Dell OS6 with a lower learning curve for IT generalists. If your traffic is mostly north-south to the core and you don't need lossless storage transport, this is the cost-appropriate, right-sized choice.
Choose the S-series for the data center fabric
Pick the S-series (e.g. S5200-ON) when you are building or expanding a server rack or a leaf/spine fabric. It is designed for 25GbE-to-server, 100GbE-uplink density, very high non-blocking throughput for east-west traffic, and DCB features (PFC/ETS/DCBX) needed for RoCE and converged storage. Reversible airflow fits hot/cold-aisle containment, and SmartFabric OS10 supports modern data center automation. If the switch sits in the same rack as your PowerEdge servers or storage, this is the line.
These are complementary, not competing. Many Dell shops run both: N3200-ON in the wiring closets for the campus/office edge and S-series in the data center racks for server and storage fabric. The deciding question is location and workload. If you are powering endpoints over copper in an office, the N3200-ON is the fit; if you are connecting servers and storage at 25/100GbE with lossless-Ethernet requirements, the S-series is the fit. Buying the data center switch for a wiring closet wastes its capabilities (and PoE is absent), while buying a campus switch for a server rack leaves you short on bandwidth and DCB features. Match the line to the role and most decisions become straightforward.
Talk to a specialistFrequently asked
Can the N3200-ON be used in a data center?
It can switch traffic anywhere, but it isn't designed for it. The N3200-ON tops out at much lower aggregate throughput than the S-series, lacks the DCB lossless-Ethernet features (PFC/ETS/DCBX) used for RoCE storage, and uses front-to-back airflow rather than the reversible hot/cold-aisle airflow of the S-series. For server-rack connectivity at 25/100GbE, the S-series is the intended line. The N3200-ON is best kept to its campus/office edge and distribution role.
Do both run the same operating system?
Not by default. The N3200-ON ships with Dell OS6, which is tuned for campus deployment and a gentler learning curve, while the S-series runs Dell SmartFabric OS10 (Enterprise Edition). Both are ONIE-based -ON hardware, so they support open network OS installation, and the N3200-ON also appears on Dell's SmartFabric OS10 hardware compatibility list. Confirm the exact OS and feature licensing for the specific SKU with your Uniqcli contact before ordering.
Which one supports PoE for access points and phones?
The N3200-ON. It offers several PoE and PoE+ models specifically so a single cable can carry both data and power to Wi-Fi access points, IP phones, and cameras at the campus edge. The S-series does not provide PoE — as a data center fabric switch it connects already-powered servers and storage, so power-over-Ethernet isn't part of its design. If powering endpoints is a requirement, that points clearly to the N3200-ON.
