Product Review

The Cisco N2K-C2248TF-E-1GE offers a high-capacity solution with its 48x100/1000Base-T and 4x10GE ports, supported by 8 Fabric Extender Transceivers, ensuring versatile connectivity options for a variety of network requirements. However, its 1.2:1 oversubscription rate may limit performance in high-demand scenarios, potentially affecting data throughput during peak operations. With hardware forwarding at 176 Gbps or 131 mpps and a fabric speed of 40 Gbps in each direction, this device balances between substantial throughput capabilities and energy efficiency, consuming a maximum of 110W under full load.


The Cisco N2K-C2248TF-E-1GE is designed to streamline data center architecture and operations by serving as a fabric extender for the Cisco Nexus 5000, 6000, 7000 series switches, and Cisco Nexus 9000 Series in Fabric Extender Mode. This product enables a cost-effective, scalable server access platform with a simplified management framework. At its core, the Cisco N2K-C2248TF-E-1GE comprises 48 ports that support 100/1000Base-T connections, alongside 4 ports for 10GE uplinks, providing flexibility for either Gigabit Ethernet or 10 Gigabit Ethernet connectivity. This range of connectivity options ensures that the fabric extender can accommodate varying networking demands, making it suitable for a wide array of data center environments. The unit also includes 8 Fabric Extender Transceivers, which are instrumental in maintaining high-speed data transmission between the fabric extender and parent Nexus switches. Key hardware specifications include: - 100BASE-T/1000BASE-T ports: These ports utilize RJ-45 connectors, ensuring compatibility with a wide range of network cables and devices. - Fabric extender fabric interfaces: The device features 4 fabric interfaces, facilitating efficient data flow within the network architecture. - Fabric speed: The Cisco N2K-C2248TF-E-1GE boasts a fabric speed of 40 Gbps in each direction, amounting to 80 Gbps full duplex. This high-speed connectivity is essential for handling substantial data volumes without bottlenecks. In terms of performance, the fabric extender is capable of hardware forwarding at 176 Gbps or 131 million packets per second (mpps), showcasing its ability to manage extensive network traffic efficiently. However, it maintains an oversubscription ratio of 1.2:1, balancing bandwidth availability with cost-effectiveness. The physical dimensions of the Cisco N2K-C2248TF-E-1GE are 1.72 x 17.3 x 17.7 inches (4.37 x 43.94 x 44.96 cm), and it weighs 17.7 lb (8.0 kg), making it a compact yet powerful component within any data center rack. Despite its substantial processing capability, the fabric extender operates with a typical input power of 95W, peaking at 110W. It draws a typical input current of 1.0A, with a maximum of 1.2A, and outputs 8A/10A (typical/maximum). Heat dissipation is managed efficiently, with typical and maximum rates of 322 and 403 BTU/hour, respectively, ensuring that the unit maintains optimal operating temperatures. Furthermore, the Cisco N2K-C2248TF-E-1GE complies with RoHS-6 regulations, underscoring Cisco's commitment to environmental sustainability by restricting the use of certain hazardous substances in electronic equipment. In summary, the Cisco N2K-C2248TF-E-1GE fabric extender offers a versatile and efficient solution for expanding data center networks. Its broad compatibility, high-speed connectivity, and efficient performance metrics make it an essential component for organizations looking to enhance their networking infrastructure while managing operational costs and complexity.
