Cisco C9300-NM-8X Catalyst 9300 Series 8x 10G Network Module

Cisco C9300-NM-8X is an 8-port 10-Gigabit Ethernet network module for Cisco Catalyst 9300 Series switches. Installed in the Catalyst 9300’s network module slot, it provides eight 10G interfaces to expand uplink and distribution bandwidth within enterprise campus networks. Eight high-speed ports give network engineers flexibility to consolidate aggregation points, create distributed uplinks to the core or distribution layer, and scale 10G connectivity as needs evolve. This module is designed specifically for Catalyst 9300 hardware and carries the part number C9300-NM-8X, ensuring compatibility with supported models and configurations in Cisco’s 9300 ecosystem. It serves as a drop-in upgrade path for increasing 10G capacity in existing Catalyst 9300 deployments, enabling higher bandwidth between access switches and core infrastructure without replacing the switch chassis.
