N2K-C2248TP-E is a Cisco Nexus 2000 Platform Chassis, offering 2 power supply, 1 Fan Modules, 48x100/1000Base-T + 4x10GE (req SFP+), 32MB buffer, and choice of airflow. Cisco Nexus 2000 Series Fabric Extenders comprise a category of data center products designed to simplify data center access architecture and operations. Nexus 2000 Series Fabric Extenders behave like remote line cards for a parent Cisco Nexus switch. The fabric extenders are essentially extensions of the parent Cisco Nexus switch fabric, with the fabric extenders and the parent switch together forming a distributed modular system. This architecture enables physical topologies with the flexibility and benefits of both top-of-rack (ToR) and end-of-row (EoR) deployments

Frequently Asked Questions
How does the N2K-C2248TP-E handle buffer-heavy applications compared to the standard Nexus 2248TP? +
The N2K-C2248TP-E is specifically engineered for environments requiring deep buffering. Featuring a 32MB buffer, this model significantly outperforms the standard 2248TP in scenarios involving bursty traffic patterns, providing enhanced support for storage applications and high-bandwidth environments where packet loss must be minimized during transient congestion periods.
What are the uplink options for the Nexus 2248TP-E Fabric Extender? +
This unit provides flexible connectivity with four 10GE uplink ports. These ports require SFP+ transceivers, allowing IT administrators to select the appropriate optics—such as SR, LR, or Twinax copper cables—based on their specific data center distance requirements and existing fiber infrastructure for parent switch connectivity.
Is the N2K-C2248TP-E suitable for high-density 1GbE access layer deployments? +
Yes, this model is an excellent choice for high-density 1GbE access. It offers 48 ports of 100/1000Base-T connectivity, enabling seamless consolidation of server racks. By utilizing the Cisco Fabric Extender architecture, it simplifies your network topology by extending the management and switching capabilities of the parent Nexus switch directly to the edge of your server environment.
Can I customize the airflow and power supply configurations for the N2K-C2248TP-E? +
Yes, the N2K-C2248TP-E supports flexible configuration options to match your data center's specific cooling design. You can select from various power supply units and airflow directions—either port-side exhaust or port-side intake—to ensure optimal thermal management and integration within your existing hot-aisle or cold-aisle containment systems.
How does the Nexus 2248TP-E integrate with my existing Cisco Nexus parent switch? +
Integration is streamlined via the Cisco Fabric Extender (FEX) architecture. The N2K-C2248TP-E connects directly to a supported Nexus parent switch, functioning effectively as a remote line card. This design consolidates your management plane, as all configuration and monitoring tasks are performed on the parent switch, reducing operational complexity across your data center fabric.
What is the primary use case for the 32MB buffer on this specific Nexus model? +
The extended 32MB buffer is ideal for virtualization clusters and distributed storage systems where I/O spikes are common. By absorbing bursts that would typically cause drops in standard-buffer switches, the N2K-C2248TP-E ensures consistent performance for sensitive traffic, making it a reliable choice for mixed-traffic environments requiring improved throughput stability.
Does the N2K-C2248TP-E support mixed-speed connectivity on its host ports? +
The 48 downlink ports are capable of auto-negotiating between 100Mbps and 1Gbps speeds, providing versatility for older legacy servers or network appliances alongside modern gigabit infrastructure. This flexibility allows the switch to serve as a bridge between diverse hardware generations within a single rack, simplifying your server lifecycle management strategy.
Is the Nexus 2248TP-E managed as a standalone device? +
No, this device does not operate as an independent switch. It is a Fabric Extender (FEX) that relies entirely on a parent Cisco Nexus switch for its control plane, software updates, and management. This zero-touch provisioning approach minimizes the need for individual device configuration, significantly speeding up the deployment process for large-scale rack environments.
How can I obtain a bulk quote for multiple N2K-C2248TP-E units for a large project? +
