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-C3850-48U-S is a powerful enterprise-grade stackable access switch built to support high-density power and connectivity demands in modern network environments. Equipped with 48 Gigabit Ethernet ports with Universal Power over Ethernet (UPOE) support, this switch can deliver up to 60W per port — double the power of standard PoE+ — making it ideal for powering next-generation endpoint devices such as IP phones, wireless access points, IP cameras, and thin clients that require higher wattage.Built on the Catalyst 3850 platform and running Cisco IOS-XE, the WS-C3850-48U-S offers a modular design with support for optional network modules, enabling flexible uplink configurations. The switch supports full StackWise-480 stacking technology, allowing multiple units to be combined into a single logical switch for simplified management and enhanced redundancy.
The "S" designation indicates the IP Services feature set is not included at the base level — this unit ships with the LAN Base feature set, making it an ideal entry point for organizations seeking robust Layer 2 switching with scalable upgrade paths. The switch also supports integrated wireless controller functionality for managing Cisco access points, unifying wired and wireless management under a single platform.
Available in New Open Box condition, this unit has never been fully deployed and retains original manufacturer components, offering enterprise-grade performance at a significantly reduced price point through WhaleyComm.

Ideal Use Cases
Enterprise Access Layer Deployment
The WS-C3850-48U-S is purpose-built for enterprise access layer networks requiring high-density power delivery. Its 48 UPOE ports support a full floor or wing of endpoint devices including IP phones, access points, and video surveillance cameras from a single switch.
High-Power Endpoint Environments
Organizations deploying next-generation devices that exceed standard PoE+ wattage — such as multi-radio Wi-Fi 6 access points or advanced IP cameras — benefit from UPOE's 60W per port capacity. This eliminates the need for additional power injectors or local power supplies at the edge.
Scalable Stacked Network Infrastructure
IT teams building scalable, simplified network cores can leverage StackWise-480 to link multiple 3850 units into a single logical switch. This reduces management overhead while providing high-availability redundancy and increased aggregate bandwidth across the stack.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
New Open Box means the unit has been opened from its original packaging but has not been fully deployed or used in a production network environment. The switch retains its original manufacturer components and is in like-new functional condition, offered at a reduced price through WhaleyComm.
Standard PoE+ (IEEE 802.3at) delivers up to 30W per port, while Cisco's Universal Power over Ethernet (UPOE) can deliver up to 60W per port. This higher wattage supports advanced endpoint devices such as multi-radio access points, video conferencing endpoints, and other high-power IP devices that exceed standard PoE+ limits.
Yes, the WS-C3850-48U-S supports Cisco StackWise-480 technology, allowing it to be stacked with other compatible Catalyst 3850 series switches. Stacking creates a single logical switch for unified management, simplified configuration, and increased redundancy — stacking cables are required and sold separately.
The "-S" suffix on this model designates the standard LAN Base feature set, which provides robust Layer 2 switching capabilities. Organizations requiring advanced Layer 3 routing features such as full IP routing protocols may need to upgrade to the IP Services feature set via a Cisco software license — please verify current licensing requirements with WhaleyComm prior to purchase.
