Network module Cisco C9300-NM-8X= — 8-port 10 Gigabit Ethernet for Catalyst 9300

The Cisco C9300-NM-8X network module adds eight 10 Gigabit Ethernet ports to compatible Cisco Catalyst 9300 switches, expanding uplink and aggregation capacity for campus and branch deployments. Designed for high-throughput uplinks, server connectivity and stack aggregation, this module provides fixed 10 GbE interfaces that integrate into the Catalyst 9300 platform to increase bandwidth and simplify network architecture.

Advantages

This network module delivers eight dedicated 10 GbE ports to enable higher uplink and distribution performance without replacing the base switch. It supports consistent 10,000 Mbit/s per port for demanding traffic patterns, reduces the need for external aggregation devices, and maintains compatibility with Cisco Catalyst 9300 switch hardware. The module helps consolidate server and uplink links while preserving the switch’s management, security and feature set.

Suitable for

• High-throughput uplink connections in campus and branch networks
• Server connectivity requiring multiple 10 GbE links
• Aggregation and stacking scenarios to increase distribution bandwidth
• Environments that require inline integration with Catalyst 9300 switch features

Key specifications

• Port count: 8 x 10 Gigabit Ethernet fixed ports
• Per-port throughput: 10 Gbit/s
• Interface type: 10 GbE optics or direct-attach depending on transceivers used
• Form factor: network module compatible with Cisco Catalyst 9300 chassis
• Use case: uplink, aggregation and server connectivity expansion

How to use

Install the module into a supported slot on a Cisco Catalyst 9300 switch following the switch hardware installation procedures and safety guidelines. Configure the new 10 GbE interfaces in the switch operating system to define VLANs, L2/L3 settings, QoS and security policies as required by the network design. Populate the ports with appropriate SFP+ transceivers or direct-attach cables compatible with the module and connected equipment.

Usage recommendations

Verify compatibility with your specific Catalyst 9300 model and software version before installation. Use compatible SFP+ optics or DACs rated for 10 GbE, plan link aggregation or port-channeling for increased resiliency, and monitor port utilization to ensure the uplink capacity meets traffic demands.
