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.
Enterprise-grade PoE+ stacking performance. Professionally tested. Backed by a Lifetime Warranty.
This refurbished Cisco Catalyst WS-C3750X-24P-L is a 24-port PoE+ stackable access switch delivering enterprise-class Layer 2 switching with 802.3at-compliant PoE+ across all ports. Every unit is professionally tested, reset to factory defaults, and ships ready to deploy. Available in LAN Base (WS-C3750X-24P-L), IP Base (WS-C3750X-24P-S), and IP Services (WS-C3750X-24P-E) license tiers to match your routing and protocol requirements.The Catalyst 3750X architecture centers on Cisco StackWise Plus technology, allowing up to nine switches to operate as a single logical unit with 64 Gbps of dedicated stack throughput. All 24 Gigabit Ethernet ports support 802.3at PoE+ at up to 30W per port, making this platform well suited for powering IP phones, wireless access points, and other converged edge devices. Modular uplink slots accept optional 1G or 10G network modules for flexible uplink design, and hot-swappable redundant power supplies protect against unplanned downtime. Cisco TrustSec, MACsec, and granular ACL support address modern campus security requirements, while IEEE 802.3az Energy Efficient Ethernet reduces power consumption during low-traffic periods.
Purchasing refurbished Cisco hardware from WhaleyComm delivers the same enterprise reliability at a fraction of new-unit cost. With 25+ years of experience and 5,000+ enterprise customers served, WhaleyComm holds ISO 9001, R2v3, e-Stewards, and UNEDA certifications — so every unit that leaves our facility has been verified to perform to manufacturer specification.

Ideal Use Cases
Campus Access Layer Deployment
The 3750X-24P delivers PoE+ power and Gigabit connectivity to IP phones, wireless access points, and end-user devices across campus access closets. StackWise Plus lets multiple switches in the same closet operate as a single logical unit, simplifying management.
Converged Voice and Wireless Infrastructure
With 802.3at PoE+ on all 24 ports, this switch can simultaneously power an entire floor of IP phones and high-density Wi-Fi 5 or Wi-Fi 6 access points without requiring external power injectors.
Branch Office Switching
The modular uplink options and flexible license tiers make the 3750X-24P a strong fit for branch offices requiring scalable Layer 2 or Layer 3 switching with optional routing protocols under IP Base or IP Services.
Small Distribution Layer
Under an IP Services license, the 3750X-24P supports BGP, full OSPF and EIGRP, VRF, and policy routing, making it capable of serving as a distribution-layer switch in smaller enterprise environments.
Network Refresh or Hardware Replacement
Organizations refreshing aging Catalyst infrastructure or replacing failed units can deploy refurbished 3750X-24P switches as direct replacements, maintaining existing stack configurations and licensing tiers at significantly reduced cost.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The three SKUs differ only in software license tier. The -L runs LAN Base, which supports Layer 2 switching and QoS but no IP routing. The -S runs IP Base, adding static routing, limited OSPF and EIGRP, and basic IPv6. The -E runs IP Services, enabling full BGP, OSPF, EIGRP, advanced IPv6, VRF, MPLS, and policy routing.
Yes. The Catalyst 3750X-24P includes a modular uplink slot that accepts optional Cisco network modules supporting 1G or 10G uplinks. This allows uplink speed to be matched to your existing core or distribution infrastructure.
Cisco StackWise Plus supports up to nine Catalyst 3750X switches in a single stack, with a dedicated stack interconnect providing 64 Gbps of total bandwidth. The entire stack is managed as a single logical switch.
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.
