Product Overview
The Cisco C9300-NM-2Q is a 2-port 40G QSFP+ uplink network module designed for use with Cisco Catalyst 9300 Series switches. It provides ultra-high-speed 40 Gigabit Ethernet uplinks, ideal for enterprise networks requiring high-bandwidth aggregation, core uplinks, or data center interconnects.
Product Description
The Cisco C9300-NM-2Q delivers 2x 40G QSFP+ ports to dramatically boost the uplink capacity of Catalyst 9300 switches. This module is hot-swappable and plugs into the modular uplink slot of supported 9300 models, allowing administrators to upgrade uplinks without any service interruption. It supports Cisco QSFP+ optics, including 40GBASE-SR4, LR4, and BiDi, making it suitable for both short and long-range fiber deployments. It also supports breakout cables, enabling 4x10G fan-out from each 40G port for flexibility. The C9300-NM-2Q is ideal for connecting access switches to high-speed core switches, data center fabrics, or distribution layers with dense traffic demands.
