Overview
N2K-C2248TF-E Overview
Cisco Nexus 2248TP-E, Full duplex
N2K-C2248TF-E is a Cisco Nexus 2248TP-E Series 1GE Fabric Extender, offering 2 power supply, 1 Fan Modules, 48x100/1000Base-T + 4x10GE (includes 8 Fabric Extender Transceivers), 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
What are the primary uplink and downlink port configurations for the Cisco N2K-C2248TF-E? +
The N2K-C2248TF-E is a high-density Nexus 2248TP-E Fabric Extender featuring 48 ports of 100/1000Base-T for downlink connectivity to end hosts. For high-speed uplinks to the parent Nexus switch, it provides four 10GE ports, which include the necessary Fabric Extender Transceivers to facilitate seamless connectivity in your data center fabric.
How does the 32MB buffer on the N2K-C2248TF-E impact network performance? +
The 32MB buffer is engineered to handle microbursts effectively, ensuring smoother traffic flow for standard data center applications. By providing increased buffering compared to standard models, this unit helps prevent packet loss during periods of transient network congestion, maintaining consistent performance for latency-sensitive traffic across your 1G host connections.
Is the Cisco N2K-C2248TF-E compatible with existing Nexus 5000 or 7000 series switches? +
This Fabric Extender acts as a remote line card for supported Cisco Nexus parent switches. It is designed to work in conjunction with Nexus 5000, 6000, and 7000 series platforms, extending the management and control plane of the parent switch to the access layer to simplify data center operations.
Does the N2K-C2248TF-E support flexible airflow and power configurations? +
Yes, this chassis is designed for versatile data center deployment. It supports a choice of port-side exhaust or port-side intake airflow, allowing you to align the unit with your specific hot-aisle or cold-aisle containment strategy. The dual power supply configuration provides critical redundancy to ensure high availability for your rack infrastructure.
What is the primary role of the Fabric Extender in a leaf-and-spine architecture? +
The N2K-C2248TF-E functions as a leaf node in a fabric topology, effectively extending the port density of the parent switch. By consolidating host connections to a top-of-rack FEX, you reduce cable complexity and centralize management, enabling a single point of configuration for your entire network fabric.
How do I manage the N2K-C2248TF-E within a Cisco NX-OS environment? +
Management is handled entirely through the parent Cisco Nexus switch. You do not need to configure the FEX independently; all policy, software updates, and management features are inherited from the upstream switch, which significantly reduces the administrative overhead required to maintain your rack-level network infrastructure.
What specific cabling is required for the 10GE uplink ports on this device? +
The N2K-C2248TF-E includes four 10GE SFP+ uplink ports that come equipped with Fabric Extender Transceivers. These are specifically designed for connecting the FEX to the parent switch within the same rack or adjacent cabinets, providing reliable, high-speed connectivity while utilizing standard fiber cabling architectures common in enterprise data centers.
Is the N2K-C2248TF-E suitable for high-density 1G server environments? +
Absolutely. With 48 ports of 1G connectivity, this device is perfectly suited for high-density server racks. It allows you to aggregate numerous 1G connections into a 10G uplink path, providing a highly scalable and cost-effective method to increase server port density without the complexity of managing a standalone access switch.
