Frequently Asked Questions
What are the primary interface capabilities of the Cisco Nexus 2348TQ? +
The Nexus 2348TQ features 48 100M/1/10GBASE-T RJ45 ports for versatile server connectivity, along with 6 40GbE QSFP+ uplink ports. This configuration provides a high-density, low-latency fabric extension solution suitable for modern data centers requiring flexible copper-based 10G migration paths.
How does the N2K-C2348TQ handle data center airflow requirements? +
This unit offers a choice of airflow directions, including port-side intake or port-side exhaust. It is equipped with three fan modules to ensure optimal thermal performance within your server rack. Selecting the correct airflow configuration is critical to matching your existing hot-aisle or cold-aisle containment strategy for maximum cooling efficiency.
Is the Cisco Nexus 2348TQ compatible with existing Nexus switches? +
Yes, this fabric extender is designed to function as a remote line card for Cisco Nexus parent switches, including the 5000, 6000, 7000, and 9000 series. By offloading complex management tasks to the parent switch, it simplifies network architecture while maintaining a single point of administration across the fabric.
What is the benefit of the 10GBASE-T support on the Nexus 2348TQ? +
The support for 10GBASE-T over standard RJ45 cabling allows for cost-effective 10GbE connectivity using existing Category 6a or Category 7 cabling infrastructure. This simplifies deployment for data centers that prefer twisted-pair copper media over optical fiber, reducing overall infrastructure costs while maintaining high-speed throughput.
How should I configure the 40G QSFP+ uplink ports on the N2K-C2348TQ? +
The 6 40G QSFP+ uplink ports provide high-bandwidth connectivity back to the parent switch. These ports require compatible QSFP+ transceiver modules or DAC cables. Proper configuration at the parent switch level is necessary to establish the fabric link and ensure full throughput capabilities across the extenders.
Does the N2K-C2348TQ support redundant power supplies? +
The chassis is shipped with two power supplies to provide N+1 or N+N redundancy, depending on your power configuration requirements. These hot-swappable power supply units are critical for maintaining continuous uptime in enterprise-grade data center environments, ensuring that a single power source failure does not disrupt network operations.
What deployment scenarios are best suited for the Cisco Nexus 2348TQ? +
This platform is ideal for large-scale data center environments needing high-density server access. It is frequently deployed in Top-of-Rack (ToR) configurations to connect a large number of servers to the core fabric, effectively managing cable congestion while providing high-performance, low-latency switching at the server edge.
Is the Cisco Nexus 2348TQ manageable as a standalone switch? +
The Nexus 2348TQ operates specifically as a fabric extender (FEX) and is managed entirely through the connected parent switch. It does not function as an independent switch. This architecture allows IT teams to manage the FEX as an extension of the parent switch's control plane, drastically reducing management overhead for large-scale deployments.
Can I obtain a bulk quote for multiple N2K-C2348TQ units? +
Absolutely. For organizations planning large-scale deployments or infrastructure refreshes, we provide competitive bulk pricing options. Simply contact our sales team with your project requirements, and we will prepare a tailored quote that reflects your specific volume needs while maintaining the highest service standards for your procurement department.
Why should I purchase my Cisco hardware from BuyRouterSwitch.com? +
