Dell PowerSwitch S-Series vs N-Series
Dell PowerSwitch S-Series
Dell PowerSwitch N-Series
Both lines are Dell PowerSwitch Ethernet switches, but they are engineered for opposite ends of the network. The S-Series is built for the data center and cloud fabric — high-density 10/25/100GbE top-of-rack and leaf-spine switching. The N-Series is built for the campus, branch, and wiring closet — Power over Ethernet access for phones, APs, and cameras, with Multi-Gig copper to the desk. For most buyers the decision isn't which is "better" but which layer of the network you're solving for: pick the S-Series when you're connecting servers and storage in a rack, and the N-Series when you're connecting end-user devices across a building.
Side by side
| Dell PowerSwitch S-Series | Dell PowerSwitch N-Series | |
|---|---|---|
| Primary role | Data center / cloud fabric: top-of-rack (ToR), leaf-and-spine, HPC and storage networks | Campus, branch, and edge access and aggregation: wiring closets and end-user connectivity |
| Port speeds & density | High-density 1/10/25/40/50/100GbE; SFP/SFP28/QSFP fiber-oriented uplinks and ToR ports | 1GbE and Multi-Gigabit (2.5/5GbE) copper access with 10/25GbE uplinks for distribution |
| Power over Ethernet (PoE) | Generally no PoE — designed for servers, storage, and switch-to-switch links | Core strength: PoE/PoE+ and 802.3bt PoE++ (up to 90W on N3200-ON) for APs, IP phones, and cameras |
| Operating system | SmartFabric OS10 (and Enterprise SONiC on -ON models) for modern, automatable data-center fabrics | Traditionally OS6 for campus features; newer -ON models support ONIE and SmartFabric OS10 |
| Fabric & automation | Built for fabric: VLT, leaf-spine, EVPN/VXLAN, and SmartFabric Services automation | Campus-oriented L2/L3 with stacking; fabric automation is a fit on the OS10-capable -ON models |
| Typical deployment | Inside the rack and the data-center spine, often paired with PowerEdge servers and PowerStore/PowerScale storage | Distributed across floors and closets, often stacked, feeding desks, Wi-Fi, and physical security |
| Resilience & airflow | Redundant hot-swappable PSUs/fans and reversible airflow options for hot/cold-aisle data centers | Access-class redundancy and stacking for closet uptime; quieter, building-friendly form factors |

Dell PowerSwitch S-Series
Dell PowerSwitch N-Series
Choose the S-Series for the data center and fabric
Pick the PowerSwitch S-Series when the switch lives in a server rack rather than a wiring closet. It is the right answer for top-of-rack server access, leaf-and-spine fabrics, HPC clusters, and storage networking where you need dense 10/25/100GbE and low-latency, non-blocking throughput. The SmartFabric OS10 foundation (with Enterprise SONiC available on -ON models) gives you VLT, EVPN/VXLAN, and automation that scale cleanly alongside PowerEdge servers and Dell storage. If PoE is irrelevant and your traffic is server-to-server, server-to-storage, or spine-to-leaf, this is the line.
Choose the N-Series for the campus and the edge
Pick the PowerSwitch N-Series when you're powering and connecting end-user and IoT devices across a building or branch. PoE/PoE+ and 802.3bt PoE++ (up to 90W on the N3200-ON) drive wireless access points, IP phones, security cameras, and badge readers from a single cable, while Multi-Gigabit copper future-proofs the run to Wi-Fi 6E/7 APs and modern desktops. Stacking simplifies closet management, and the access-class form factors are quieter and shallower than data-center gear. If your switch sits in a wiring closet feeding desks and APs, the N-Series is purpose-built for it.
These lines rarely compete head-to-head; they're complementary halves of the same network. Specify the S-Series for everything inside the data-center rack and spine — server access, storage, and OS10/SONiC-based fabric — and the N-Series for the campus access layer where PoE, Multi-Gig copper, and stacking matter most. Many Dell environments run both: N-Series in the closets and S-Series in the racks. For a buyer, the cleanest qualifying question is simply, "Is this switch connecting servers or end-user devices?" — that answer points to the right family almost every time. Where a campus deployment wants OS10 consistency end to end, the OS10-capable N-Series -ON models bridge the two.
Talk to a specialistFrequently asked
Can the S-Series and N-Series run the same Dell OS10 / SmartFabric software?
Not uniformly. The S-Series is built around SmartFabric OS10 (with Enterprise SONiC on -ON models), which is its native data-center operating system. The N-Series traditionally runs Dell's campus-focused OS6, though newer open-networking models such as the N2200-ON and N3200-ON support ONIE and can run SmartFabric OS10. If running OS10 across both the access and data-center layers is a requirement, scope the OS10-capable -ON N-Series models specifically rather than assuming every N-Series unit qualifies.
Which one do I need for Power over Ethernet (Wi-Fi APs, IP phones, cameras)?
The N-Series. PoE is a defining feature of the campus access line, with models offering PoE+, and 802.3bt PoE++ up to 90W per port on the N3200-ON — enough for high-power APs, PTZ cameras, and pan/tilt devices. The S-Series is a data-center line and generally does not provide PoE, because the devices it connects (servers, storage, other switches) are independently powered.
For a leaf-and-spine data center fabric, which line should I quote?
Quote the S-Series. It's engineered for ToR/leaf and spine roles with high-density 10/25/40/100GbE ports, low latency, and SmartFabric OS10 features like VLT and EVPN/VXLAN, plus SmartFabric Services automation. The N-Series isn't designed for spine-and-leaf data-center fabrics; it's optimized for campus access. Model selection within the S-Series then depends on port speeds and density — confirm the server NIC speeds and uplink/oversubscription targets before locking in a specific SKU.
