C9500-NM-2Q Cisco Catalyst 9500 2x40GBE Network Module
Cisco C9500-NM-2Q Catalyst 9500 2-Port 40G Network Module
High-Performance 40GbE Expansion for Catalyst 9500 Series Core Switches
The Cisco Catalyst C9500-NM-2Q is a high-performance 40 Gigabit Ethernet network module engineered to extend the uplink capacity of Cisco Catalyst 9500 Series core switches. Featuring two QSFP+ ports, this hot-swappable module delivers up to 80 Gbps of aggregate bandwidth, enabling high-speed connectivity between core, distribution, and data center layers.
Designed for modern enterprise and campus core environments, the C9500-NM-2Q eliminates network bottlenecks by providing scalable, high-density 40G uplinks. It supports a wide range of Cisco QSFP+ transceivers and direct-attach copper cables, allowing flexible deployment from short-range connections to long-distance fiber links.
With seamless integration into Cisco IOS XE and Cisco DNA Center, the module ensures simplified deployment, centralized management, and enhanced operational visibility. Its hot-pluggable design enables installation or replacement without powering down the switch, ensuring continuous uptime for mission-critical networks.
Ideal for enterprise core aggregation, high-speed campus backbones, and data center interconnects, the Cisco C9500-NM-2Q provides the scalability, performance, and investment protection required for evolving high-bandwidth infrastructures.

FAQs:
Q1. Can this module be used in Catalyst 9300 or 9200 switches?
No. The C9500-NM-2Q is physically and electronically designed specifically for the Catalyst 9500 Series. The 9300 and 9200 series use their own specific sets of network modules (e.g., C9300-NM or C9200-NM).
Q2. Does this module support 4x10G breakout functionality?
Yes, on supported Catalyst 9500 platforms running appropriate Cisco IOS-XE versions, the 40G ports can be configured to "break out" into 4 x 10G SFP+ ports using a MPO-to-8-LC breakout cable.
Q3. Is a reboot required after inserting the C9500-NM-2Q?
No. The module is hot-swappable. However, it is always a best practice to check the console logs to ensure the module is recognized and the interfaces are initialized correctly.
Q4. Can I mix this module with other C9500 modules in the same switch?
The Catalyst 9500 switches that support modular uplinks typically have one slot. You can choose either the 8x10G (C9500-NM-8X) or this 2x40G module depending on your specific port requirements.
Q5. What transceivers are recommended for short-distance connections?
For connections within the same rack or room, the QSFP-H40G-CU3M (3-meter Direct Attach Cable) or the QSFP-40G-SR4 (Short Range fiber) are the most common and cost-effective choices.
