Cisco Nexus N3K-C3232C 32-Port 100GbE QSFP28 1U Data Center Switch: This is a 1RU fixed-configuration top-of-rack data center switch from Cisco's Nexus 3200 platform, providing 32 ports of QSFP28 100 Gigabit Ethernet. The switch is purpose-built for high-density spine-leaf and leaf-of-rack deployments running NX-OS. This is a switch chassis with NX-OS, not a modular Nexus 9500 line card and not a Nexus 9300 model. This is a refurbished unit.
Engineering Context
The N3K-C3232C delivers 6.4 Tbps of bidirectional switching capacity and supports line-rate Layer 2 and Layer 3 forwarding across all 32 QSFP28 ports. Each QSFP28 port can be operated at 100GbE, 40GbE, or broken out into 4x 25GbE or 4x 10GbE using supported breakout cables, giving up to 128 25GbE-class ports per switch. The platform supports VXLAN, EVPN, MP-BGP and standard data center fabric features in NX-OS. Front-to-back and back-to-front airflow SKUs exist within the family; verify airflow direction on the chassis label before integrating with a hot-aisle/cold-aisle layout.
Deployment & Use Cases
Top-of-rack 100GbE leaf in VXLAN/EVPN spine-leaf fabrics. High-density 25GbE host aggregation using QSFP28-to-4xSFP28 breakout. 100GbE spine for medium-scale data centers. Storage network aggregation for NVMe/TCP and iSCSI environments. Lab and pre-production data center fabric mock-ups.

Compatibility & Hard Constraints
Operates with QSFP28 100GbE optics, QSFP+ 40GbE optics, and Cisco-supported QSFP28-to-4xSFP28 / QSFP+-to-4xSFP+ breakout cables. Software image, license entitlements, and serial-bound features may need to be re-applied via Cisco's normal entitlement process; T.E.S IT-SOLUTIONS does not transfer Cisco software licenses with the hardware. Not a Nexus 9300/9500 chassis and not interchangeable with ACI spine roles requiring 9500-series line cards. Verify airflow direction matches your rack layout before installation.
