Cisco Systems, Inc. WS-C3850-12S-E Network Switch

Cisco Catalyst WS-C3850-12S-E is a stackable IP Services-enabled Ethernet switch housed in a 1U chassis that provides 12 SFP ports for fiber connectivity and a single network module slot for optional expansion. Powered by a 350 W AC power supply, this model is designed for reliable operation in campus wiring closets and small data centers. Running Cisco IOS XE with the IP Services feature set, it delivers advanced Layer 2/3 features, security options, and centralized management while integrating with other Catalyst devices for scalable networks. The 12 SFP ports support a wide range of SFP transceivers for flexible fiber links to servers, storage, or uplinks, enabling diverse deployment options without sacrificing space. Because it is part of the Catalyst 3850 family, it is designed to be stackable with other Catalyst 3850 switches to create a modular, resilient network fabric. Typical applications include mid-sized campus distribution and edge aggregation where fiber-based connectivity is preferred, as well as compact deployments in small data centers requiring a feature-rich, scalable access switch.
