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.
Professionally tested to factory specification. Backed by 25 years of enterprise trust.
This refurbished Cisco NXA-PDC-500W-B (341-0594-01) is a 500W DC power supply designed for Cisco Nexus 9000 series fixed-port switches. It features reversed airflow — port-side intake — making it the correct choice for hot-aisle containment environments where airflow runs from the port side toward the rear of the rack. Every unit is professionally tested and reset to factory defaults before shipment.The NXA-PDC-500W-B operates on a -48V DC to -60V DC input and delivers up to 500 watts of output power to the switch chassis. It is hot-swappable, supporting 1+1 redundant power configurations to maintain uptime during maintenance or component replacement. Cisco Nexus 9000 series power supplies in this family carry 80 Plus Platinum efficiency ratings, minimizing heat output and energy costs in dense data center deployments.
Purchasing refurbished through WhaleyComm delivers the same enterprise-grade Cisco hardware at a fraction of new list price. WhaleyComm is ISO 9001, R2v3, and e-Stewards certified, and every unit ships with a Lifetime Warranty — no time limits, no questions asked. With 25+ years of experience and 5,000+ enterprise customers, we stand behind every unit we ship.

Ideal Use Cases
Hot-Aisle Containment Data Centers
The reversed port-side intake airflow draws cool air from the cold aisle through the front ports and exhausts warm air into the hot aisle, aligning perfectly with standard hot-aisle containment architectures in modern data centers.
DC-Powered Colocation Facilities
Facilities running -48V or -60V DC plant power — common in carrier-grade and colocation environments — can deploy this unit without AC-to-DC conversion infrastructure, reducing complexity and improving efficiency.
1+1 Redundant Power Configurations
Cisco Nexus 9000 series fixed-port switches support dual power supply slots, and the NXA-PDC-500W-B supports hot-swap 1+1 redundancy, allowing one supply to be replaced without powering down the switch.
Replacement and Spare Inventory
IT teams supporting fleets of Cisco Nexus 9300 series switches benefit from keeping a refurbished NXA-PDC-500W-B on hand as a verified spare, reducing mean time to recovery when a field unit fails.
Budget-Conscious Network Expansion
Organizations scaling out Nexus 9000 fabric deployments can use certified refurbished power supplies to equip additional switches at significantly lower cost than purchasing new, without compromising reliability or warranty coverage.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The -B suffix denotes reversed airflow, meaning air is drawn in from the port side (front) and exhausted out the rear — this is port-side intake, also called front-to-back airflow. The -PI suffix also denotes port-side intake. Both use the same airflow direction; always verify against your specific switch model's compatibility list before ordering.
Yes. The NXA-PDC-500W-B is hot-swappable and supports 1+1 redundant power supply configurations on compatible Cisco Nexus 9000 series switches. This allows the unit to be replaced without powering down the switch chassis, minimizing disruption to network operations.
The NXA-PDC-500W-B is compatible with Cisco Nexus 9000 series fixed-port switches including the 9372PX, 9372TX, 9372PX-E, 9372TX-E, and related models. Always verify compatibility against your specific switch model and chassis revision before installation. For environment-specific verification, contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com.
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.
