## Summary description

Cisco Catalyst 3850 4 x 10GE is a network expansion module designed for Cisco Catalyst 3850 switches. It provides four 10 Gigabit Ethernet ports for increased uplink or aggregation capacity. The module enables higher bandwidth connectivity for data centers, branch aggregation, and high-performance access layers, allowing faster data transfer and better handling of demanding applications.

## Long description

The Cisco Catalyst 3850 4 x 10GE network module expands Catalyst 3850 switches by adding four 10 Gigabit Ethernet ports to support higher uplink and aggregation bandwidth. Designed for environments that require increased throughput, the module integrates with the 3850 platform to provide additional capacity for data-intensive tasks, uplink redundancy and simplified network architecture. It is intended for use in campus distribution, branch aggregation and access layer scenarios where higher-speed connections are needed between switches, routers and servers.
Advantages
The module delivers four native 10 Gigabit Ethernet interfaces, enabling higher throughput and reduced bottlenecks on uplinks. Integration with the Catalyst 3850 platform preserves unified management and familiar configuration workflows, while the compact form factor conserves chassis slot space. By providing multiple high-speed ports in a single module, it supports link aggregation and redundancy strategies to improve availability and performance without requiring a separate aggregator device.
Suitable for
Uplink and aggregation between access switches and distribution/core layers
High-bandwidth connectivity for virtualization hosts and server farms
Campus networks requiring increased uplink capacity and redundancy
Branch offices needing consolidated high-speed links to data centers
Key specifications
Number of ports: four 10 Gigabit Ethernet ports
Port type: 10GE interfaces compatible with standard SFP+ transceivers
Intended platform: compatible with Cisco Catalyst 3850 series chassis
Function: uplink/aggregation module to increase switch bandwidth
Form factor: modular network interface designed for insertion into the host switch
How to use
Install the module into an available network module slot on a compatible Catalyst 3850 switch following Cisco installation procedures and observing electrostatic discharge precautions. After physical installation, populate the ports with appropriate 10GE SFP+ transceivers and connect fiber or DAC cables as required. Configure the switch ports in the device management interface to match network design—assign VLANs, set speed/duplex where applicable, and configure link aggregation, spanning tree or LACP policies according to operational needs.
Usage recommendations
Use industry-standard SFP+ optics or direct-attach cables certified for 10 Gigabit operation and verify transceiver compatibility with the Catalyst 3850 platform. Plan port usage for redundancy and capacity—spread critical uplinks across multiple ports and enable link aggregation where higher throughput or failover is required.
