Core Functionality of the CN129-PDC-3000W-B=
The CN129-PDC-3000W-B= is a 3,000-watt AC power supply unit (PSU) designed for Cisco’s high-performance networking hardware, such as the Catalyst 9500 and 9600 series switches. It provides redundant, hot-swappable power to ensure uninterrupted operation in mission-critical environments like data centers or enterprise core networks.
Key Technical Advantages and Use Cases
- High Efficiency: Operates at 94% efficiency under typical loads, reducing energy waste and operational costs.
- Modular Redundancy: Supports N+1 power redundancy configurations to eliminate single points of failure.
- Compatibility: Optimized for Cisco chassis systems requiring sustained 3000W input, such as the C9600R.
CN129-PDC-3000W-B= vs. Standard 2200W PSUs: Critical Differences
| Feature | CN129-PDC-3000W-B= | 2200W Base Model (e.g., C9K-PWR-2200W) |
|---|---|---|
| Max Output | 3000W | 2200W |
| Efficiency | 94% | 92% |
| Deployment | High-density chassis/edge compute | Mid-tier access layer switches |
The 3000W capacity addresses power demands for PoE++ (90W per port) deployments and GPU-driven edge computing nodes, which standard 2200W units cannot reliably support.
Addressing Common User Concerns
Q: Can this PSU integrate with older Catalyst 9400 systems?
A: No—the CN129-PDC-3000W-B= is backward-compatible only with Catalyst 9500/9600 chassis. Always verify compatibility using Cisco’s Power Calculator.
Q: Does itmall.sale offer genuine Cisco-certified units?
A: Yes. For verified inventory, refer to [“CN129-PDC-3000W-B=” link to (https://itmall.sale/product-category/cisco/).
Final Perspective: When to Prioritize This PSU
The CN129-PDC-3000W-B= is non-negotiable for enterprises scaling IoT deployments or AI workloads at the edge. While its upfront cost is higher than lower-wattage alternatives, the long-term ROI from energy savings and reduced downtime justifies the investment—especially in environments where power redundancy is a compliance requirement.
