N2K-C2248TP-E Overview

The Cisco Nexus® 2000 Series Fabric Extenders comprise a category of data center products designed to simplify data center access architecture and operations. The Cisco Nexus 2000 Series uses the Cisco® fabric extender architecture to provide a highly scalable unified server-access platform across a range of 100 Megabit Ethernet, 1 and 10 Gigabit Ethernet, unified fabric, copper and fiber connectivity, and rack and blade server environments. The platform is well suited to support today’s traditional 1 Gigabit Ethernet environments while allowing transparent migration to 10 Gigabit Ethernet, virtual machine-aware unified fabric technologies.

The Cisco 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 .

The Cisco Nexus 2000 Series architecture provides the following benefits:

- Architecture flexibility: A common, scalable, and adaptive architecture across data center racks and points of delivery (PoDs)[1] supports various server options, connectivity options, physical topologies, and evolving needs.
- Highly scalable server access: 1 and 10 Gigabit Ethernet server access is scalable, with no reliance on Spanning Tree Protocol.
- Simplified operations: One single point of management and policy enforcement using upstream Cisco Nexus switches eases the commissioning and decommissioning of server racks through zero-touch installation and automatic configuration of fabric extenders.
- Increased business benefits: Consolidation, cabling reduction, rack-space reduction, reduced power and cooling, investment protection through feature inheritance from the parent switch, and the capability to add functions without the need for a major equipment upgrade of server-attached infrastructure all contribute to reduced operating expenses (OpEx) and capital expenditures (CapEx).

The Cisco Nexus 2000 Series design aligns with that of servers. It offers front-to-back cooling, compatible with data center hot-aisle and cold-aisle designs, all switch ports at the rear of the unit in close proximity to server ports, and all user-serviceable components accessible from the front panel. It also offers back-to-front cooling, with switch ports in front of the chassis, aligned with the cold aisle, for optimized cabling in network racks. The Cisco Nexus 2000 Series is built for nonstop operation, with redundant hot-swappable power supplies and a hot-swappable fan tray with redundant fans. Its compact 1-rack-unit (1RU) form factor takes up relatively little space, making it easy to incorporate into rack designs. The fabric extenders are available in several models to provide speed, connectivity, and port-density options.

Frequently Asked Questions

Is the Cisco N2K-C2248TP-E available refurbished? +
Yes. This page lists the refurbished condition currently available from BuyRouterSwitch. Availability can change, especially for bulk orders.
Can I request bulk pricing for N2K-C2248TP-E? +
Yes. Businesses, resellers, MSPs, government buyers and procurement teams can request custom quantity pricing.
Does BuyRouterSwitch ship N2K-C2248TP-E internationally? +
BuyRouterSwitch ships enterprise IT hardware to customers in the United States and international markets, subject to destination and product restrictions.
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.
