Cisco Nexus 9300‑FX Series 48‑Port Gigabit Switch

Product Description

The Cisco N9K‑C9348GC‑FXP is a high‑performance fixed‑port data center switch from the Nexus 9300‑FX Series, engineered for enterprise and cloud‑scale networks. It provides 48 x 10/100/1000 Mbps copper ports for dense server or access connectivity, 4 x 1/10/25 Gbps SFP28 uplink ports, and 2 x 40/100 Gbps QSFP28 uplinks for high‑speed aggregation or spine connections. This flexible port mix enables seamless migration from traditional Gigabit environments to modern 25/100 Gbps architectures without changing the platform.

Built for Cisco NX‑OS operating system, the N9K‑C9348GC‑FXP supports advanced Layer 2/Layer 3 features, segmentation, automation, and programmability. It offers robust scalability with large MAC and route tables, comprehensive multicast support, and rich quality‑of‑service controls — making it ideal for top‑of‑rack (ToR) deployments, data center access layers, and enterprise aggregation tiers.
