Tested
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.
This professionally tested and refurbished Cisco Catalyst WS-C3850-24XS-S is a 1U, stackable enterprise-class access layer switch delivering 24 × SFP+ ports with support for both 1G and 10G optics. Running Cisco IOS IP Base, it ships reset to factory defaults and verified against original Cisco specifications — ready for immediate rack deployment.Powered by Cisco's Unified Access Data Plane (UADP) ASIC, the WS-C3850-24XS-S delivers a switching capacity of 640 Gbps and a forwarding rate of 454.55 Mpps for wire-speed performance at scale. The switch supports Cisco StackWise-480 technology with up to 480 Gbps stacking bandwidth and a maximum stack of 9 switches, all managed under a single IP address. With 4 GB DRAM and 4 GB Flash, an integrated wireless controller supporting up to 100 access points and 2,000 wireless clients, Flexible NetFlow (48,000 flows), and advanced security features including 802.1X, ACL support, and DHCP snooping, this platform is built for demanding enterprise access and aggregation environments. An optional network module slot (compatible with C3850-NM-4-10G, C3850-NM-8-10G, C3850-NM-2-40G) provides flexible uplink expansion.
Sourced from enterprise refresh cycles and fully refurbished through WhaleyComm's ISO 9001-certified process, the WS-C3850-24XS-S delivers carrier-grade 10G switching performance at a fraction of new list price. For organizations standardizing on Cisco Catalyst infrastructure, this unit represents a proven, cost-effective path to high-density 10G access without compromise.

Ideal Use Cases
High-Density 10G Access Layer
The 24 SFP+ ports support both 1G and 10G optics, making this switch ideal for access layer deployments where servers, storage, or upstream aggregation devices require wire-speed 10G connectivity.
Enterprise Campus Aggregation
With 640 Gbps switching capacity and StackWise-480 stacking up to 9 switches at 480 Gbps stack bandwidth, the WS-C3850-24XS-S is well-suited as a campus aggregation node handling high-throughput traffic from multiple access switches.
Wired and Wireless Network Convergence
The built-in wireless controller supports up to 100 access points and 2,000 wireless clients per switch or stack, enabling IT teams to converge wired and wireless policy enforcement on a single platform without a separate controller appliance.
Data Center Edge / Top-of-Rack
The 1U form factor, high forwarding rate of 454.55 Mpps, and 10G fiber uplinks make this switch a capable top-of-rack or data center edge unit for SMB or branch data center environments.
StackWise-480 Scalable Core for SMB
Stacking up to 9 units under a single management IP address allows smaller organizations to build a scalable, resilient core that grows with the network without requiring a full chassis upgrade.
Cisco Catalyst Refresh / Standardization
Organizations standardized on Cisco Catalyst IOS make this a drop-in replacement or upgrade from older 3750/3750X platforms, maintaining operational familiarity while gaining 10G density.

The WS-C3850-24XS-S delivers a switching capacity of 640 Gbps and a forwarding rate of 454.55 Mpps, providing wire-speed performance for high-density 10G environments. These figures are per Cisco's published datasheet for the 24-port 10G SFP+ model.
Yes. The switch supports Cisco StackWise-480 technology, allowing up to 9 switches to be stacked with 480 Gbps of stack bandwidth. The WS-C3850-24XS-S running IP Base can only stack with other Catalyst 3850 IP Base switches.
This model does not support PoE. The 24 SFP+ ports accept both 1G and 10G SFP/SFP+ optics, giving flexibility to use existing 1G investments while upgrading to 10G as needed. The switch also has one optional network module slot compatible with C3850-NM-4-10G, C3850-NM-8-10G, and C3850-NM-2-40G modules.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
