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 WS-X4K-CLOCK-E is a Refurbished clock module engineered to deliver precise timing and synchronization within the Cisco Catalyst 4500 series switch platform. Clock modules play a critical role in maintaining switching fabric integrity by providing a stable reference clock signal that coordinates data flow across the chassis backplane, helping to prevent timing-related errors and packet loss in high-demand enterprise environments.This Refurbished unit has been inspected and verified to meet functional standards, offering a reliable, budget-conscious alternative to new hardware without sacrificing performance. For organizations managing large-scale network infrastructure, having a tested spare clock module on hand can dramatically reduce Mean Time to Repair (MTTR) during unexpected hardware failures.
The WS-X4K-CLOCK-E is designed to slot directly into compatible Catalyst 4500 series chassis, making it straightforward to deploy as a replacement in existing installations. Its passive role in the chassis means it integrates seamlessly without requiring complex configuration changes.
WhaleyComm sources Refurbished Cisco hardware through quality-controlled processes, providing enterprises, educational institutions, and service providers with dependable components at a fraction of the cost of new. At $185.00, the WS-X4K-CLOCK-E represents outstanding value for network administrators looking to maintain infrastructure resilience and reduce capital expenditure on spare parts inventory.
