Cisco N2K-C2248TP-E-1GE 48X 100/1000 T+4X10GE N2KC2248TPE1GE

Description:

The Cisco N2K-C2248TP-E-1GE Nexus 2248TP-E Fabric Extender is used in data center environments to provide high-density Gigabit Ethernet access while operating as a remote line card for a parent Cisco Nexus switch. Commonly deployed in top-of-rack (ToR) architectures, it connects servers and endpoints while centralizing management through upstream Nexus 5000, 6000, 7000, or 9000 series switches. Maintenance teams and system integrators use this unit for scalable server access, simplified network architecture, and replacement of traditional access switches.

Applications:

The Cisco Nexus 2248TP-E is commonly used in enterprise data centers, virtualization clusters, storage networks, and high-density server environments where centralized switching and low-latency connectivity are required. It is ideal for fabric extender (FEX) architectures that reduce management complexity and improve scalability.
