Core Product Positioning
The C9200-NM-8G is a high-density, cost-effective modular uplink expansion module designed for Cisco Catalyst 9200 series modular access switches, built on Cisco DNA intent-based enterprise LAN architecture. It delivers an aggregate 8Gbps full-duplex uplink bandwidth to connect multi-stack access layer switches to campus aggregation/core switches, supporting flexible fiber and copper 1G uplink media for variable cabling distance requirements.
This module supports OIR (Online Insertion and Removal) hot-swap operation, enabling uplink capacity upgrades or hardware replacement without power cycling the host switch or disrupting active network traffic. It fully aligns with Catalyst 9200’s Layer 2/Layer 3 forwarding ASIC architecture and Cisco ACT2 enterprise security compliance standards.
