Nexus 9300 48-Port 10GBASE-T Data Center Switch
Product Description
The Cisco N9K-C9372TX-E from Cisco Systems is a high-density 10-Gigabit Ethernet switch in the Nexus 9300 Series, engineered for enterprise and cloud data centers that require copper-based 10G connectivity with high-speed uplinks and cloud-scale performance.
Designed primarily for top-of-rack and leaf-layer deployments, the switch offers 48 fixed 1/10GBASE-T server ports along with 6× 40G QSFP+ uplink ports, enabling efficient aggregation into spine fabrics. With support for Cisco NX-OS and Cisco ACI, it provides automation, programmability, telemetry, and policy-driven networking for modern software-defined data centers.
The N9K-C9372TX-E is ideal for organizations using copper server infrastructure while still requiring scalable fabric design, low latency switching, and high throughput performance.
