C9300-48UB-A Description

C9300-48UB-A is a feature-rich access switch with 48 × 1 Gb UPOE ports (60 W per port) and 10 Gb / 25 Gb uplinks for high-speed aggregation. It features a 256 Gbps non-blocking switching fabric, ensuring smooth forwarding at 190.48 Mpps, even under full PoE load. The 64 MB packet buffer enhances performance during traffic bursts, reducing packet loss in environments with high congestion or large file transfers. StackWise-480 enables up to eight switches to operate as a single unit with 736 Gbps total stack bandwidth and sub-50 ms fail-over. The Network Advantage license unlocks advanced Layer 3 routing, SD-Access micro-segmentation, and Encrypted Traffic Analytics (ETA). Dual 1100 W AC power supplies provide up to 445 W PoE budget to power demanding devices, while redundant fans ensure reliable cooling.
