Cisco C9300-NM-2Y Network Switch Module

The Cisco C9300-NM-2Y is a network switch module designed for the Cisco Catalyst 9300 Series, providing two 10G SFP+ ports to extend uplink and aggregation capacity. Intended for enterprise access and distribution layers, the module enables higher throughput and flexible connectivity for servers, storage and uplink links while maintaining compatibility with Cisco Catalyst 9300 platform management and feature set.

Advantages

This module delivers two 10G SFP+ ports in a compact, hot-pluggable form factor compatible with the Catalyst 9300 chassis. It supports higher-bandwidth uplinks and reduces congestion on access switches, while integrating with existing Cisco management, redundancy and security features. The module’s design emphasizes reliability and predictable performance in multi-vendor environments where SFP+ optics are used.

Suitable for

• Expanding uplink capacity on Catalyst 9300 switches
• Connecting to data center switches or aggregation devices at 10 Gbps
• High-performance links to servers or storage arrays using SFP+ optics
• Deployments requiring redundant uplinks and scalable port density

Key specifications

• Interface: 2 × 10 Gigabit SFP+ ports
• Form factor: Hot-pluggable network module for Catalyst 9300 chassis
• Supported link speeds: 10 Gbps per port
• Compatibility: Cisco Catalyst 9300 Series module slot
• Optics: Supports SFP+ transceivers (sold separately)

How to use

Install the module into an available network module slot on a Cisco Catalyst 9300 Series switch following Cisco’s hardware installation procedure. After physical installation, configure the new 10G interfaces through the switch operating system to assign VLANs, set interface parameters, enable link aggregation or configure redundancy protocols as required by the network design. Insert compatible SFP+ transceivers into the module ports and connect fiber or DAC cables to establish links.

Recommendations

Use manufacturer-recommended SFP+ transceivers and cabling to ensure compatibility and full performance. Verify software compatibility and licensing on the Catalyst 9300 switch before deployment, and plan for redundancy and monitoring to maintain availability in enterprise environments.
