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 C4KX-PWR-750AC-F is a purpose-built 750-watt AC power supply unit engineered for use in Cisco Catalyst 4500-X Series fixed-configuration switches. Designed with front-to-back airflow (F = front-to-back), this PSU aligns with standard hot-aisle/cold-aisle data center cooling architectures, helping maintain thermal efficiency in structured rack environments.



As a field-replaceable unit, the C4KX-PWR-750AC-F supports hot-swap capability when a second power supply is installed, enabling power redundancy without network downtime. This makes it an ideal choice for enterprises that require continuous uptime in their core or aggregation switching layers.



This refurbished unit has been inspected and tested to meet functional standards, offering enterprise-grade performance at a reduced investment. WhaleyComm sources refurbished Cisco hardware through qualified channels, making it a cost-effective solution for organizations looking to expand, replace, or maintain their existing Catalyst 4500-X infrastructure.



Whether you are refreshing aging power components, building a redundant power configuration, or deploying additional Catalyst 4500-X units across branch or campus locations, the C4KX-PWR-750AC-F delivers the reliability Cisco is known for — backed by WhaleyComm's technical expertise and competitive pricing.

Ideal Use Cases
Power Redundancy in Enterprise Campus Networks
Deploy a second C4KX-PWR-750AC-F alongside an existing PSU in a Catalyst 4500-X switch to achieve fully redundant power. This eliminates single points of failure and supports continuous network availability for critical campus infrastructure.
Data Center Aggregation Layer Refresh
Replace aging or failed power supplies in Catalyst 4500-X aggregation switches without replacing the entire chassis. The front-to-back airflow design integrates seamlessly with standard hot-aisle/cold-aisle data center cooling layouts.
Cost-Effective Branch and Campus Expansion
Equip newly deployed or secondary Catalyst 4500-X switches with refurbished power supplies to reduce capital expenditure during network expansion. This allows IT teams to scale infrastructure while maintaining budget efficiency without sacrificing performance.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The "-F" designates front-to-back airflow direction, meaning air flows from the front of the chassis to the rear. This is a common configuration for data centers using hot-aisle/cold-aisle cooling setups, and it is important to match airflow direction across all components in the same chassis.
Yes, the C4KX-PWR-750AC-F supports hot-swap replacement when a second power supply is installed and active in the chassis. This allows the faulty or aging PSU to be removed and replaced without interrupting network operations or causing downtime.
Yes, this is a refurbished unit, meaning it is a previously used Cisco component that has been inspected and tested to verify functional operation. WhaleyComm sources refurbished hardware through reputable channels to ensure reliability, and it is offered at a reduced price compared to new units.
The C4KX-PWR-750AC-F is designed for use with Cisco Catalyst 4500-X Series switches. It is not intended for use in other Catalyst families or chassis that use different PSU form factors. Please confirm your specific switch model supports the C4KX power supply format before ordering.
