Cisco C9300-NM-2Q Catalyst 9300 2x40GE Network Module Enterprise Cisco Catalyst 9300 2-Port 40 Gigabit Ethernet Network Module for High-Speed Uplink Connectivity The Cisco C9300-NM-2Q 2-Port 40 Gigabit Ethernet QSFP+ Network Module is a high-performance uplink expansion module designed for Cisco Catalyst 9300 Series Switches. Built to meet the growing bandwidth requirements of enterprise campus, distribution, and data center networks, it provides two 40 Gigabit Ethernet QSFP+ ports that deliver high-speed fiber connectivity for aggregation, backbone, and core network applications. Purpose-built for the Cisco Catalyst 9300 Series, the C9300-NM-2Q integrates seamlessly with the switch architecture to provide scalable and reliable uplink expansion without replacing existing hardware. Supporting an aggregate uplink bandwidth of up to 80 Gbps, the module enables organizations to handle increasing network traffic while maintaining wire-speed performance for mission-critical business applications. The module supports a broad range of Cisco QSFP+ 40 Gigabit Ethernet transceivers, including SR4, LR4, ER4, CSR4, BiDi optics, and Direct Attach Copper (DAC) cables, providing deployment flexibility for short-, medium-, and long-distance fiber connections across enterprise and campus infrastructures. Designed with a hot-swappable plug-in form factor, the Cisco C9300-NM-2Q can be installed or replaced without powering down the host switch, minimizing maintenance windows and reducing network downtime. Powered directly by the Catalyst 9300 switch, it requires no additional external power while maintaining enterprise-class reliability. Running with Cisco IOS XE, the module supports advanced networking technologies including IEEE 802.3ad Link Aggregation (LACP), IEEE 802.1Q VLAN tagging, jumbo frames, hardware-based Quality of Service (QoS), and platform-dependent MACsec encryption. It also integrates with Cisco DNA Center, Cisco Prime Infrastructure, and Cisco SD-Access, enabling centralized management, network automation, policy-based segmentation, and simplified lifecycle operations. Designed for modern enterprise environments, the Cisco C9300-NM-2Q provides the performance and scalability required for high-speed network backbones, campus aggregation, and data center interconnects while helping organizations prepare for future bandwidth demands. Ideal for enterprise campus networks, high-speed switch uplinks, core network aggregation, fiber backbone expansion, data center connectivity, and business network upgrades, the Cisco C9300-NM-2Q 2-Port 40 Gigabit Ethernet QSFP+ Network Module delivers scalable 40GbE connectivity, enterprise-class reliability, and seamless integration with Cisco Catalyst 9300 switching platforms.
