C3850-NM-4-10G Use Case
Campus Distribution Aggregation for High-Bandwidth Applications
In a large enterprise campus network supporting HD video conferencing, VoIP and large file transfers, the Cisco Catalyst 3850 4 x 10GE Network Module (C3850-NM-4-10G) aggregates multiple 1 GbE access switches onto a high-speed backbone. This deployment reduces congestion, delivers sub-millisecond latency for real-time services and consolidates management under Cisco DNA Center for simplified provisioning and troubleshooting.
Data Center Access-to-Core Uplink for Virtualized Workloads
A mid-size data center running VMware and containerized applications uses the C3850-NM-4-10G module to provide four dedicated 10 GbE uplinks between access and core layers. By offloading north-south traffic onto high-capacity links, organizations accelerate live VM migration, achieve up to 40% higher throughput and maintain consistent performance under variable loads.
Wireless and IoT Edge Backhaul with Enhanced Segmentation
In a distributed healthcare environment with Wi-Fi 6 access points and IoT medical sensors, the Cisco Catalyst 3850 4 x 10GE Network Module dedicates 10 GbE ports for wireless backhaul and IoT gateways. This architecture enforces VRF-based segmentation, improves packet forwarding rates by over 30% and ensures compliance with stringent HIPAA security standards.

Questions & Answers
What is the Cisco Catalyst 3850 4 x 10GE Network Module (C3850-NM-4-10G)?
The Cisco Catalyst 3850 4 x 10GE Network Module (C3850-NM-4-10G) is an optional uplink expansion module that provides four hot-swappable 10 Gigabit Ethernet SFP+ ports for high-speed connectivity on Catalyst 3850 switches.
Which Cisco Catalyst 3850 switch models are compatible with the C3850-NM-4-10G?
The C3850-NM-4-10G is compatible with all Cisco Catalyst 3850 series fixed-configuration switches, including 3850-24, 3850-24P, 3850-48, and 3850-48P models.
How many ports does the Cisco Catalyst 3850 4 x 10GE Network Module provide and what type are they?
The module provides four hot-swappable SFP+ ports, each supporting 10 Gigabit Ethernet connectivity for flexible uplink or aggregation links.
What SFP+ transceivers and cable types are supported by the C3850-NM-4-10G?
It supports Cisco-approved 10GBASE-SR, 10GBASE-LR, 10GBASE-ER, DWDM SFP+ optics and direct attach copper (DAC) cables for up to 7 meters of short-range connection.
What performance and bandwidth does the Catalyst 3850 4 x 10GE module deliver?
The module delivers up to 40 Gbps of aggregated uplink bandwidth, ensuring wire-speed forwarding, low latency, and high throughput for demanding enterprise and data center applications.
How do I install the Cisco Catalyst 3850 4 x 10GE Network Module?
Power down the switch, remove the blank expansion cover, slide the C3850-NM-4-10G into the module slot until it locks, then power on. The switch auto-detects and initializes the module.
Is the Cisco Catalyst 3850 4 x 10GE Network Module hot-swappable?
No. To ensure hardware integrity, the switch must be powered off before installing or removing the network module.
What Cisco IOS software features are supported with the C3850-NM-4-10G?
Under Cisco IOS XE, the module supports the Catalyst 3850 Universal Image, including advanced security, QoS, NetFlow, automation and programmability features.
What are the power consumption and environmental requirements for the 4 x 10GE module?
