NEW Cisco C9350-NM-8Y expansion module - 8 x 25G/10G/1G or 4 x 50G

Overview

The Cisco C9350-NM-8Y is a field-replaceable uplink network module designed specifically for Cisco C9350 Series Smart Switches. It provides flexible high-speed fiber uplink connectivity for enterprise campus, aggregation, and access-layer environments where scalable bandwidth and migration flexibility are required. The module supports eight SFP56-based interfaces operating at 1G, 10G, or 25G speeds, with the option to convert the top-row ports into four 50G interfaces for higher-capacity uplinks. Designed for modern enterprise workloads including Wi-Fi 6/7, 5G integration, video collaboration, and high-density access deployments, the C9350-NM-8Y enables organizations to scale bandwidth without replacing the switch platform.
