A large university deploys the C9300-NM-2Q on Catalyst 9300 switches as dual 40 Gigabit Ethernet uplinks between building distribution and core layers. This configuration consolidates high-density Wi-Fi, BYOD and IoT traffic into a single, resilient spine, eliminating bottlenecks during peak lecture and lab sessions. Outcome: sub-millisecond latency, 3× performance headroom and simplified campus expansion without forklift upgrades.
A nationwide retail chain migrates its point-of-sale and inventory applications to a private cloud. By installing the Catalyst 9300 2 × 40GE Network Module in access switches, each leaf node attains high-capacity uplinks to the spine layer. Benefit: 50% faster transaction processing, consistent SLA-grade connectivity and non-disruptive scaling across 500+ store locations.
A financial services firm integrates on-premise trading platforms with AWS and Azure to support high-frequency trading and analytics. The C9300-NM-2Q module on Catalyst 9300 switches delivers dual 40GE links over DWDM circuits to public cloud edge routers. Result: sub-millisecond round-trip times, 2× aggregate throughput and strict micro-segmentation for regulatory compliance.

The C9300-NM-2Q is a modular expansion card that adds two 40 Gigabit Ethernet QSFP+ ports to Catalyst 9300 switches, delivering high-bandwidth uplinks for enterprise and campus deployments.
The C9300-NM-2Q is supported on all Cisco Catalyst 9300 Series switch models equipped with Modular Uplink Slots, including C9300-24 and C9300-48 variants.
Each QSFP+ port on the C9300-NM-2Q module supports 40 Gbps native speed and can be configured as four 10 Gbps channels via breakout cables.
The module is compatible with Cisco QSFP-40G-SR4, QSFP-40G-LR4, and QSFP-40G-CSR4 transceivers, as well as MPO to LC breakout assemblies for 4×10 Gbps operation.
Power down the switch, align the module in the uplink slot, insert firmly until latched, then power on. The IOS-XE software will automatically detect and enable the new ports.
No additional license is required. The module’s 40 Gbps ports are enabled under the existing Network Advantage or Network Essentials license on the Catalyst 9300 switch.
Use cases include high-density data center spine-and-leaf topologies, campus core aggregation, virtualization backhaul, and high-performance server connectivity.
The C9300-NM-2Q consumes up to 15W and operates in Catalyst 9300–supported ambient temperatures of 0° to 45°C with front-to-back airflow.
Yes. Each QSFP+ port can be split into four 10 Gbps channels using Cisco-compatible MPO-to-LC breakout cables, subject to platform breakout licensing and bandwidth limits.
You can monitor throughput, error counters, latency, buffer utilization, and link status via IOS-XE CLI or Cisco DNA Center for real-time visibility.
No. To ensure stability and proper enumeration, Cisco recommends powering down the switch before inserting or removing the C9300-NM-2Q module.
By providing dual 40 Gbps uplinks, the C9300-NM-2Q enables link aggregation, Equal-Cost Multipath (ECMP), and Cisco StackWise redundancy for uninterrupted connectivity.
The module is covered under Cisco’s limited lifetime warranty and can be backed by Cisco SMARTnet for 24×7 hardware replacement and software updates.
Use IOS-XE policy maps and class maps to assign priority queues, set DSCP values, and apply rate limiting. Configuration changes take effect immediately.
Typical port-to-port latency on the module is under 2 microseconds, ensuring low-latency performance for data center and campus environments.
The module is available through Cisco authorized resellers, distributors, and the Cisco online store. Contact your Cisco partner for volume pricing and availability.
