Network Switch Module Cisco C9300-NM-4G Gigabit Ethernet

The Cisco C9300-NM-4G Gigabit Ethernet module is an optional uplink module compatible with Cisco Catalyst 9300 Series switches. It provides four Gigabit Ethernet ports to extend uplink capacity and integrate with existing Catalyst 9300 deployments. The default Catalyst 9300 switch configuration does not include this network module and it is installed separately when additional uplink ports are required.

Advantages

The C9300-NM-4G offers four 1 Gbps Ethernet ports for increased uplink bandwidth and flexible connectivity options. Its design ensures compatibility with Cisco Catalyst 9300 switches, enabling straightforward integration and consistent management within the Catalyst platform. By adding this module, organizations can scale port density without replacing the base switch.

Suitable for

• Expanding uplink ports on Cisco Catalyst 9300 switches
• Connecting access layer switches to distribution or core layers
• Small to medium enterprise environments requiring additional Gigabit uplinks
• Environments where modular, field-replaceable uplink options are preferred

How to use

Power down the Catalyst 9300 switch or follow the platform’s hot-swap procedure if supported, then insert the C9300-NM-4G module into the designated network module slot. Secure the module according to Cisco’s installation instructions and boot the switch. After installation, verify port status and configure uplink interfaces through the switch’s management interface or CLI to match network requirements.

Recommendations

Install this module when additional Gigabit uplinks are needed; ensure software and hardware compatibility with your specific Catalyst 9300 model and IOS/EOS image. Follow Cisco’s official installation and safety guidelines, and perform configuration backups before making changes.
