Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.

Tested to factory specification. Backed by 25 years of enterprise trust.

The Cisco Catalyst WS-C3850-12S-S is a Refurbished enterprise-grade stackable switch built for demanding network environments. Equipped with 12 SFP (Small Form-Factor Pluggable) ports, this switch is purpose-built for fiber-based uplinks and high-density access or distribution deployments where optical connectivity is preferred over copper.

Running the IP Base feature set, the WS-C3850-12S-S supports essential enterprise routing and switching capabilities including static routing, EIGRP stub, and core QoS features — making it well-suited for structured campus and branch network designs. The Catalyst 3850 Series is also recognized for its support of full StackWise-480 stacking technology, allowing multiple switches to be combined into a single logical unit for simplified management and increased resilience.

Sourced and tested as a Refurbished unit, this switch has undergone inspection to ensure reliable operation, providing a cost-effective path to deploying proven Cisco infrastructure. It is an ideal choice for IT teams looking to extend the life of a tested platform, build out secondary network tiers, or deploy lab and staging environments without the premium cost of new hardware.

With Cisco's trusted IOS-XE software foundation and a compact fixed form factor, the WS-C3850-12S-S remains a dependable choice for fiber-first switching at the access or distribution layer.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The IP Base feature set includes foundational enterprise switching and routing capabilities such as static routing, EIGRP stub, and standard QoS. IP Services adds full Layer 3 routing protocols such as OSPF, BGP, and EIGRP in full mode — customers requiring advanced dynamic routing should verify which feature set meets their needs before purchasing.
Yes, the Cisco Catalyst 3850 Series supports StackWise-480 stacking technology, enabling multiple switches to operate as a single logical unit. Physical stacking requires Cisco StackWise-480 stack cables, which are sold separately and are not included with this unit.
No, SFP transceivers are not included with this Refurbished unit unless explicitly stated in the product listing. Customers will need to source compatible Cisco-approved SFP modules separately to activate the fiber ports.
Refurbished means this unit is a previously deployed or off-lease Cisco switch that has been inspected and tested for functionality. It is not new-in-box hardware, but it provides a cost-effective way to deploy proven enterprise infrastructure. Customers are encouraged to contact WhaleyComm for details on any available warranty or return policy options.
