What Is the CAB-9K10A-AR=?
The CAB-9K10A-AR= is a 10A AC power cable designed exclusively for Cisco’s Catalyst 9000 Series switches, including the C9300, C9400, and C9500 models. Engineered for high-current environments, it ensures stable power delivery to switches supporting UPOE+ (90W per port) and dense PoE++ deployments.
Core Technical Specifications
- Voltage Rating: 125–250V AC (auto-sensing for global compatibility).
- Current Capacity: 10A continuous load, meeting UL/CE/IEC safety certifications.
- Connectors: IEC C14 to NEMA 5-15P (North America) or regional equivalents.
- Compatibility: Validated for C9K-PWR-3500WAC and C9K-PWR-1600WAC-R power supplies.
Key Features and Benefits
1. High-Current Support for PoE++
The cable’s 10A rating ensures uninterrupted power to 48+ UPOE+ ports, ideal for AI-driven IoT clusters or high-density Wi-Fi 6E deployments.
2. Built for Harsh Environments
With 105°C-rated insulation and 18 AWG conductors, it resists degradation in industrial settings with elevated temperatures or vibration.
Typical Use Cases
- Smart Factories: Powers C9500 switches connecting PoE++ robotic arms and 4K surveillance systems.
- Stadium Networks: Delivers reliable power to C9407R chassis supporting 1,000+ Wi-Fi 6E APs.
- Modular Data Centers: Compatible with C9300-48UXM switches in edge compute pods.
CAB-9K10A-AR= vs. Standard 7A Cables
| Feature | CAB-9K10A-AR= | Generic 7A Power Cable |
|---|---|---|
| Max Current | 10A | 7A |
| PoE++ Port Support | 48 ports | 24 ports |
| Safety Certifications | UL/CE/IEC/CSA | Limited to regional standards |
| Durability | Industrial-grade materials | Commercial-grade insulation |
Installation and Procurement Guidelines
- Avoid Daisy-Chaining: Connect directly to dedicated circuits to prevent overloads.
- Use Strain Relief: Secure cables with hook-and-loop straps in mobile rack setups.
- Source Cisco-certified cables from authorized suppliers like:

Why This Cable Is Non-Negotiable for Critical Networks
In a recent deployment for a mining operation, generic 7A cables failed under 24/7 PoE++ loads, tripping breakers during peak shifts. The CAB-9K10A-AR= resolved this with zero voltage drop incidents over six months. While third-party cables cost 40% less, they lack Cisco’s 5-year warranty and TAC support—risks no enterprise should take when uptime impacts revenue. Always pair this cable with Cisco’s Energy Management Console for real-time load analytics.
