N9348Y2C6D-SE1U combines 48 fixed 25G SFP28 server-facing ports with two 100G QSFP28 ports and six 400G QSFP-DD ports in a 1U data-center switch. The Layer 3 design integrates data processing units alongside the switching ASIC, separating networking functions from accelerated services. Cisco N9300 Series Smart Switches connect bare-metal servers, virtualized workloads, and the surrounding fabric while providing hardware resources for separately licensed security services. Fixed uplinks do not require a removable network module, and the non-PoE configuration requires connected equipment to use its own power source. N9324C-SE1U instead provides 24 native 100G ports, making native server-link speed a principal distinction between these family members. The 48-port 25G configuration addresses server connectivity rather than copper endpoint access.

800G DPU service throughput identifies the acceleration resource for supported services, not Ethernet switching capacity. A fully shared 64 MB on-die packet buffer holds traffic within the forwarding path, while line-rate MACsec operates on every data port. N9348Y2C6D-SE1U runs Cisco NX-OS with 64 GB of system memory and 240 GB of SSD storage, keeping system resources distinct from the DPU's separate memory. Network operations use Nexus Dashboard and programmable interfaces including RESTCONF, NETCONF, and gNMI, with model-driven telemetry for network visibility. Initial configuration begins through the local console before the out-of-band management connection is established. Stateful Layer-4 segmentation is not automatically included: DPU acceleration requires DCN Premier and separate Hypershield licensing, with security functions subject to service availability. DPUs can be turned off when their services are inactive, allowing networking operation without keeping unused service-processing functions powered. The switching ASIC and DPU therefore have separate roles when assessing connectivity and security requirements.
ORM Systems offers N9348Y2C6D-SE1U new sealed or certified refurbished: new orders carry up to a 3-year extended warranty, refurbished orders up to 1 year, and every condition includes 30-day returns, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, optics bay recognition, PSU status, fan status, and clean boot; firmware is verified and configurations are wiped to factory default. Specify condition, airflow, power configuration, and software entitlements on the PO; Cisco's separate limited hardware warranty is 1 year. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.
| Key Specs | Key Spec Values |
|---|---|
Operating System | Cisco NX-OS |
Port Configuration | 48x25G SFP28 / 2x100G QSFP28 / 6x400G QSFP-DD |

Cooling | 6x NXA-SFAN-35CFM-PI / 6x NXA-SFAN-35CFM-PE |
During a server-link migration, the cable plan may require breakout connections rather than exclusively native-speed links. Supported breakout modes include 4x100G, 4x25G, and 4x10G. Match each selected mode to the peer interface and optical assembly, and identify the required breakout connections before issuing the purchase order.
When keeping a replacement chassis on hand, N9348Y2C6D-SE1U= is the spare configuration and excludes power supplies and fans. Compatible components must therefore be assigned for transfer or ordered separately. Confirm the intended component transfer, airflow configuration, and complete replacement bill of materials before the purchase order is released.
During bench staging, terminal settings must match the console connection before configuration begins. The serial settings are 115200 baud, eight data bits, one stop bit, and no parity. Include console access in the staging checklist and verify terminal compatibility before finalizing the staging requirements on the purchase order.
Native RJ-45 copper server connections
Server-facing connections use 48 SFP28 cages rather than native RJ-45 access ports. The RJ-45 network connector serves out-of-band management, not copper server access.
Stateful security without additional licensing
DPU acceleration requires DCN Premier, while Layer-4 stateful segmentation also requires separate Hypershield licensing and service availability. Hardware purchase alone does not supply these security entitlements.
Mixed airflow component reuse
Fan modules and power supplies must share one airflow direction throughout the chassis. Mixing port-side intake components with port-side exhaust components is not a supported cooling configuration.

N9348Y2C6D-SE1U identifies the Cisco Smart Switch with 48 25G ports, two 100G ports, six 400G ports, and 800G DPU service capacity. The complete PID selects this hardware configuration; it does not select an Essentials, Advantage, or Premier software subscription. Those software entitlements are selected separately.
N9300 Series Smart Switches support NX-OS CLI, Nexus Dashboard, RESTCONF, NETCONF, gNMI, and REST API management. Initial CLI access uses the console, followed by the out-of-band management connection. Security management uses the Cisco Hypershield on-premises controller or Cisco Cloud Control when the required security services are available and enabled.
N9348Y2C6D-SE1U supports XF-class Cisco DCN Essentials, Advantage, and Premier subscriptions for 3-year, 5-year, or 7-year terms. Essentials provides basic networking capabilities, Advantage adds enhanced features, and Premier supplies the highest tier. Smart Licensing Using Policy tracks usage and reports it to Cisco Smart Software Manager.
N9348Y2C6D-SE1U hardware alone does not include the licensing needed for Hypershield stateful segmentation. DPU acceleration requires DCN Premier, and Layer-4 stateful segmentation requires a separate Hypershield license when available. Include the required software entitlements and confirm security-service availability rather than treating the integrated DPUs as an included security subscription.
N9348Y2C6D-SE1U provides two fixed 100G QSFP28 ports and six fixed 400G QSFP-DD ports alongside its 48 server-facing SFP28 ports. Supported breakout modes include 4x100G, 4x25G, and 4x10G. Select the breakout assembly and peer-port configuration together rather than assuming that every connection uses its native cage speed.
N9348Y2C6D-SE1U uses two power supplies for 1+1 redundancy. Port-side intake pairs NXA-PAC-1100W-PI2 supplies with NXA-SFAN-35CFM-PI fans; port-side exhaust pairs NXA-PAC-1100W-PE2 supplies with NXA-SFAN-35CFM-PE fans. Fan and supply airflow must match throughout the chassis, so specify one consistent direction for the complete order.
NXK-ACC-KIT-1RU is a supported rack-mount kit for N9348Y2C6D-SE1U. The switch occupies 1U and fits a standard equipment rack. Specify the mounting accessory explicitly when the order must include installation hardware, and verify the rack or cabinet requirements before finalizing the installation bill of materials.
Cisco has not announced an end-of-sale date for N9300 Series Smart Switches. N9348Y2C6D-SE1U remains an available model in this family. Hardware lifecycle status is separate from the selected software subscription term, which buyers must specify independently when ordering the required networking features and associated software entitlements.
ORM Systems offers N9348Y2C6D-SE1U new sealed or certified refurbished; Cisco provides a separate 1-year limited hardware warranty. ORM's new warranty is up to a 3-year extended term, and certified refurbished coverage is up to 1 year. Every condition includes 30-day returns; terms apply. Refurbished units are inspected and bench-tested.
N9348Y2C6D-SE1U is the standard switch configuration, whereas N9348Y2C6D-SE1U= is a spare that excludes power supplies and fans. The base model suits a complete switch order; the equals-sign spare suits a buyer who will transfer compatible components or explicitly order those components separately for the replacement chassis.
N9348Y2C6D-SE1U provides 48 native 25G ports, while N9324C-SE1U provides 24 native 100G ports. Both belong to the N9300 Series Smart Switches family. Choose the first for native 25G server connections; choose the second when server interfaces require native 100G ports rather than 25G connections.
