What Is the C9300X-NM-4C=?
The Cisco C9300X-NM-4C= is a 4-port copper network module designed to expand the capabilities of Catalyst 9300X Series switches. It adds 4x 10/25G MultiGigabit Ethernet ports to compatible chassis, enabling high-speed uplinks or dense server connectivity in enterprise and data center environments. The “NM” designation indicates its role as a hot-swappable, modular upgrade, while the “=“ suffix denotes a spare/replacement SKU.

Technical Capabilities
- Port Speed: Supports 10GBase-T and 25GBase-T over RJ45 connectors, ideal for copper-based infrastructure.
- Power Efficiency: Backward-compatible with NBASE-T (1/2.5/5Gbps) for legacy devices, reducing cabling costs.
- Performance: Leverages Cisco’s UADP 3.0 ASIC for line-rate throughput and low-latency forwarding, critical for AI/ML workloads or storage networks.
- Scalability: Integrates with StackWise-480 for unified management across stacked switches.
――――――――――――
Compatibility Requirements
This module is compatible only with Catalyst 9300X switches (e.g., C9300X-24Y-E, C9300X-48HX). It does not function with non-9300X models like the C9300-48T. Installation requires an available network module slot and Cisco IOS-XE 17.x or later.
――――――――――――
Key Use Cases
- Data Center Edge: Connects servers or storage arrays using cost-effective copper cabling.
- High-Density Offices: Provides 25G uplinks for bandwidth-heavy applications like 4K video editing or CAD tools.
- IoT Aggregation: Powers PoE+ devices (e.g., PTZ cameras, APs) via compatible switch PSUs.

Practical Perspective
The C9300X-NM-4C= is a cost-effective upgrade for organizations needing high-speed copper connectivity without overhauling existing cabling. However, its value diminishes in fiber-dominated cores or environments requiring 40/100G speeds. If your network relies on RJ45-based servers or legacy NBASE-T devices, this module is a strategic add-on—but prioritize fiber modules for future-proof scalability.
