C9200-NM-4G - Cisco Catalyst 9200 4x1GE Network Module

Cisco C9200-NM-4G — Catalyst 9200 4×1GbE Network Module

What it is

C9200-NM-4G is an expansion network module for Cisco Catalyst 9200 Series switches.
It adds 4 × 1 Gigabit Ethernet (1 GbE) copper ports to a compatible 9200 chassis, giving extra access or uplink connectivity without needing external switch ports.

Why buyers pick C9200-NM-4G (plain English)

Extra access/Uplink ports
Provides four additional 1 GbE RJ-45 ports for access or uplinks when the base switch needs more copper connectivity.

Modular flexibility
Installs neatly in the Catalyst 9200’s network module slot, so you can expand port capacity without swapping the entire switch.

Cisco IOS-XE integration
Managed with the same IOS-XE feature set as the base switch for consistent configuration, visibility, and monitoring.

Keeps cabling simple
Standard copper RJ-45 ports mean you can use existing Cat5e/Cat6 cabling without worrying about optics.

Great for access layers
Ideal for wiring closets, small server connections, or edge aggregation where extra 1 GbE ports are needed.

Where it fits (and when to choose something else)

Perfect for:

• Catalyst 9200 switches needing more 1 GbE ports

• Edge access deployments with copper connectivity

• Environments using existing copper cabling

• Small server or management network links

Choose something else if:

• You need fiber uplinks → use SFP/SFP+ uplink modules

• You need higher speeds → 10G/25G uplink modules or switches with built-in high-speed ports

• You want multigigabit access → switches/modules that support 2.5/5/10 Gb copper

TL;DR

C9200-NM-4G is Cisco’s Catalyst 9200 network module with four 1 GbE copper ports — a simple way to expand access connectivity on your switch at the edge of the network.
