What Is the C9300X-NM-2C= Module?

The ​​C9300X-NM-2C=​​ is a ​​dual-port 40G QSFP+ network module​​ designed for Cisco Catalyst 9300 Series switches. It adds high-speed uplink connectivity to existing Catalyst 9300 deployments, enabling seamless integration into data center spines, campus cores, or bandwidth-intensive enterprise networks.

Key Technical Advantages

​​1. High-Density 40G Uplink Expansion​​
The module adds ​​two 40G QSFP+ ports​​ to compatible Catalyst 9300 switches, such as the C9300X-48HX or C9300X-48HXN. This allows ​​aggregated throughput of 80G per module​​, ideal for connecting to core switches, storage arrays, or cloud gateways without replacing existing hardware.

​​2. Future-Proofing with Flexible Speeds​​
Each 40G port supports ​​breakout configurations​​ (e.g., 4x 10G or 2x 25G), enabling adaptive scaling for mixed-speed environments. This flexibility is critical for enterprises transitioning to higher-speed backbone infrastructures.

​​3. Simplified Scalability​​
The module’s ​​hot-swappable design​​ minimizes downtime during upgrades. IT teams can expand uplink capacity without powering down switches—a must for 24/7 operations like healthcare or financial services.

​​4. Enhanced Security and Visibility​​
Integrated ​​MACsec encryption​​ (up to 256-bit) secures data in transit across high-speed links, meeting compliance requirements for industries like government or education.

Addressing Common Deployment Questions

​​Q: Which Catalyst 9300 switches support this module?​​
The C9300X-NM-2C= is compatible with ​​Catalyst 9300X models​​ (e.g., C9300X-48HX, C9300X-48HXN) and requires ​​Cisco IOS XE 17.6.1 or later​​.

​​Q: Can it coexist with other modules in a stack?​​
Yes. The Catalyst 9300 chassis supports ​​multiple modules simultaneously​​, allowing hybrid configurations (e.g., 40G uplinks + PoE modules) for diverse workloads.

​​Q: Does it support advanced routing protocols?​​
With Cisco DNA Advantage licensing, the module enables ​​BGP, OSPF, and EIGRP​​, making it suitable for enterprises merging campus and data center fabrics.
