Core Functionality & Design Purpose

The ​​C9300X-NM-8M=​​ is a ​​Network Interface Module (NIM)​​ designed for Cisco Catalyst 9300X Series switches, adding ​​8x MultiGigabit Ethernet ports​​ (1/2.5/5/10 Gbps) with ​​802.3bt PoE++​​ support. This module transforms base switch configurations into ​​high-density power-over-Ethernet (PoE) hubs​​, ideal for Wi-Fi 6E/7 APs, IoT gateways, or advanced AV systems.

Port Flexibility & Power Budget

Each of the 8x MultiGig ports delivers ​​up to 90W of PoE++​​, enabling simultaneous power and data delivery to devices like ​​pan-tilt-zoom cameras​​, ​​digital signage​​, or ​​wireless APs​​ without external injectors. Ports auto-negotiate between 1G, 2.5G, 5G, and 10G speeds, ensuring backward compatibility with legacy devices.

Deployment Scenarios & Use Cases

• ​​High-density wireless edge​​: Expand existing Catalyst 9300X switches to support 802.11ax/7 APs requiring MultiGig uplinks.
• ​​IoT convergence​​: Power and connect industrial sensors, building automation controllers, or smart lighting systems.
• ​​Unified PoE++ aggregation​​: Centralize power delivery for distributed edge nodes while maintaining wire-speed throughput.

Compatibility & Installation Requirements

This NIM is compatible with ​​Catalyst 9300X switches featuring modular uplink slots​​, such as the C9300X-24Y-A or C9300X-48HX-1E. Installation requires ​​Cisco IOS XE 17.6.1 or later​​ to enable full PoE++ and MultiGig auto-sensing functionality.

Thermal & Power Considerations

The module operates within ​​-5°C to 45°C​​ ambient temperatures and shares the switch’s ​​EnergyWise​​ power management. Total PoE budget depends on the host switch’s power supply (e.g., 1100W/1400W PSUs), with dynamic allocation to prevent overloads.

Licensing & Operational Simplicity

No additional licenses are required for basic PoE++ or MultiGig functionality. However, ​​Cisco DNA Advantage​​ is needed for features like SD-Access segmentation or encrypted traffic analytics tied to the ports.

Procurement & Availability

For verified pricing and lead times, refer to [“C9300X-NM-8M=” link to (https://itmall.sale/product-category/cisco/). Ensure your host switch has an available NIM slot and sufficient PSU capacity before ordering.

Why This Module Solves Critical PoE Scaling Challenges

Having integrated multiple NIMs into campus deployments, the ​​C9300X-NM-8M=​​ eliminates the need for standalone PoE switches in distributed topologies. Its auto-negotiating MultiGig ports future-proof for Wi-Fi 7 transitions, while 90W PoE++ slashes midspan injector costs in large-scale IoT rollouts. For enterprises needing to scale power and bandwidth without rearchitecting access layers, this module is a tactical upgrade.
