Frequently Asked Questions

What are the primary port specifications for the Cisco Nexus 2148T Fabric Extender? +

The N2K-C2148T-1GE features 48 fixed 10/100/1000BASE-T Ethernet host ports for server connectivity and four 10 Gigabit Ethernet fabric uplinks. These uplinks utilize SFP+ modules to connect directly to the parent Cisco Nexus switch, effectively extending the fabric and simplifying your data center network architecture while maintaining high-speed performance.

How does the Nexus 2148T integrate into an existing Cisco data center environment? +

The Nexus 2148T operates as a remote line card for a parent Cisco Nexus switch, such as the 5000 or 7000 series. By utilizing the Cisco Fabric Extender (FEX) technology, all management and configuration tasks are handled at the parent switch, significantly reducing management complexity and overhead while allowing for a single point of administration.

Is the Nexus 2148T suitable for high-density server rack deployments? +

Absolutely. With a 1U rack-mount form factor, the N2K-C2148T-1GE is specifically engineered for high-density server environments. Its ability to provide 48 Gigabit Ethernet ports in a compact design helps save rack space and reduces cabling requirements by aggregating multiple server connections into a consolidated uplink path to the top-of-rack or end-of-row switch.

What is the expected performance when using the Nexus 2148T for virtualization workloads? +

This Fabric Extender is designed to support virtualization by providing consistent port features and policy enforcement across your server access layer. By extending the parent switch's feature set directly to the server, it ensures that virtual machine traffic benefits from the same robust performance, security, and traffic prioritization policies as the core network infrastructure.

Does the Nexus 2148T support advanced Layer 3 routing features? +

The N2K-C2148T-1GE functions primarily as a Layer 2 device that acts as an extension of the parent switch's fabric. It does not perform local Layer 3 routing; instead, all traffic requiring Layer 3 processing is forwarded upstream to the parent Nexus switch. This design keeps the access layer simplified while leveraging the high-performance routing capabilities of the core switches.

What type of cabling is required for the 10G uplink ports on the N2K-C2148T-1GE? +

The four 10 Gigabit Ethernet fabric uplinks utilize SFP+ transceivers, providing flexibility in cabling based on your data center distance requirements. You can utilize SFP+ Direct Attach Copper cables for short-reach, top-of-rack connections or optical SFP+ transceivers with fiber optic cabling for longer reaches to end-of-row configurations, ensuring optimal signal integrity across the fabric.

How should I handle power redundancy for the Nexus 2148T in a production rack? +

This unit is designed for enterprise reliability and supports dual, hot-swappable power supply units. By connecting these to independent power sources, you ensure continuous operation even during a power supply failure. We recommend maintaining a redundant power configuration to meet high-availability standards required in critical data center and mission-critical server environments.

Can the Nexus 2148T be managed through the same interface as other Nexus switches? +

Yes, management of the Nexus 2148T is entirely centralized. Because it is a FEX, it has no separate local management interface or configuration file. You manage all connected host ports directly from the command line interface of the parent Nexus switch, allowing for unified provisioning and simplified software upgrades across the entire fabric.

How can I obtain a bulk quote for the Nexus 2148T from BuyRouterSwitch.com? +
