The Cisco Catalyst C9500-NM-8X is a modular uplink expansion module for Catalyst 9500 Series switches, designed to add high-speed 10 Gigabit Ethernet connectivity for aggregation and inter-switch links. It provides 8 × 10 GbE SFP+ ports, all compatible with standard SFP/SFP+ optics, enabling flexible deployment across enterprise campus distribution and core environments that require elevated uplink bandwidth without replacing base hardware. The module is hot-swappable, allowing insertion and removal without powering down the chassis, and integrates seamlessly into supported Catalyst 9500 platforms to expand port density and uplink options.
