Cisco C3850-NM-4-1G-RF 4 x 1GE Network Module | Catalyst 3850, Enterprise — C3850-NM-4-1G-RF

Expand Catalyst 3850 switching capacity with a Cisco refurbished 4 x 1GE network module. The C3850-NM-4-1G-RF is built for environments that need additional uplink density without the expense and disruption of a full switch replacement. For infrastructure teams, this kind of module matters because it preserves the installed platform while adding the ports needed for aggregation, access, or distribution changes. It is a practical choice when you want to extend the service life of a Cisco switching investment and keep the network aligned with existing operational standards. Refurbished Cisco hardware also helps procurement teams balance budget control with platform consistency. Instead of introducing mixed-vendor expansion hardware, this module keeps the deployment inside the Cisco ecosystem, which simplifies support planning, spare strategy, and lifecycle management. Use it where four additional 1GE connections create immediate value: uplink expansion, replacement of failed expansion hardware, or capacity growth in a standardized Catalyst 3850 environment. Ideal For Adding uplink ports to a Cisco Catalyst 3850 switch Replacing a failed network module in an existing Catalyst 3850 Extending switch capacity in enterprise access layers Standardizing spare modules for Cisco campus networks Why This Product 1 Adds four 1GE ports without a chassis replacement 2 Cisco refurbished module for platform-matched expansion 3 Better fit for standardized Catalyst 3850 environments than mixed-vendor add-ons 4 Lower-cost capacity growth versus full switch refresh
