The Cisco Nexus 2232TM 10GBASE-T Fabric Extender, part number N2K-C2232TM, is a high-performance expansion module used in data centre environments requiring efficient connectivity between servers and network infrastructure. It features 32 ports that support 10GBASE-T Ethernet, enabling transmission speeds of up to 10 Gbps over standard twisted-pair copper cables, which may be advantageous in environments where fibre optic cabling is not feasible or desired.
This fabric extender operates seamlessly with its upstream Cisco Nexus switches, such as the Nexus 5000 or Nexus 7000 series, and acts as a remote line card, extending the reach of the Nexus family without increasing management complexity. The device supports FEX Technology, ensuring that operations such as forwarding decisions remain centralised at the parent Nexus switch to maintain scalable and consistent network management.
The Cisco Nexus 2232TM remains flexible in terms of topology configuration, allowing it to be employed in top-of-rack (ToR) and end-of-row (EoR) deployments. In addition to its primary 10GBASE-T interfaces, it sports eight 40-Gbps uplink ports (QSFP+), providing robust connectivity back to the core switch. These links support daisy-chaining or multi-tiered arrangements within the network, enabling high availability and reducing latency through optimised data paths.
Designed for high-density server environments, the Nexus 2232TM is built to offer low power consumption and operational efficiency. It also includes Cisco features like 802.1Q VLAN tagging, link aggregation protocols, and model-driven programmability to meet the high demands of enterprise-scale networks.
