Product Overview

The WS‑C3850‑12XS‑S is Cisco Catalyst 3850 enterprise‑class stackable Layer‑3 switch with twelve SFP+ ports for 1‑Gigabit or 10‑Gigabit fiber‑link connections. It belongs to Cisco’s fixed‑form access‑aggregation switching portfolio, built on IOS‑XE operating system for campus and data‑center network deployments.

StackWise‑480 enables multiple physical switches to combine into one logical switch with high‑speed 480 Gbps stacking backplane, improving network scalability and resiliency. StackPower technology shares power resources across stacked members to deliver power redundancy. This IP‑Base licensed unit supports rich enterprise functions including static‑and‑dynamic routing, ACL security policies, advanced QoS, VLAN segmentation and multicast services. SFP+ slots accept varied optical transceivers to match fiber‑cable distance requirements. Hot‑swap fans and power supplies reduce maintenance downtime. Original OEM production is discontinued; units are widely available as refurbished / new‑old‑stock spare‑parts for existing enterprise‑network upgrade and site‑maintenance projectsCisco.

Application Notes

‑ SFP+ transceivers are sold separately; verify Cisco‑compatible transceiver compatibility before deployment. ‑ Hot‑swap power‑supply and fan replacement shall be performed with chassis powered‑on; follow ESD anti‑static procedures. ‑ Install in standard 19‑inch equipment rack; maintain proper front‑to‑back airflow to avoid thermal overheating. ‑ IP‑Base license does not include advanced enterprise‑feature sets; feature‑license upgrade is required for additional capabilities. ‑ Not PoE‑capable model; no power output to connected field devices. ‑ Typical deployment: enterprise campus aggregation layers, industrial‑plant data networks, small‑medium data‑center top‑of‑rack networks, network‑equipment spare‑part stocking and legacy‑network retrofit.
