Introduction to the CP-7811-NC-K9= The CP-7811-NC...
Core Design and Regional Compatibility
The C9K-PWR-CAB-AC-UK= is a region-specific AC power cable tailored for UK installations of Cisco Catalyst 9000 Series switches like the Catalyst 9300, 9400, and 9500. It features a C19 connector (IEC-60320) for the switch and a BS 1363 (UK 3-pin) plug for compatibility with standard UK wall outlets. Built with 14 AWG copper wiring, it supports high-current loads required for PoE++ deployments, ensuring minimal power loss over its 4.3-meter length.
Key Advantages Over Generic UK Cables
- Compliance: Meets UK CA Certification, CE Marking, and RoHS standards for electrical safety and environmental compliance.
- Durability: Reinforced insulation withstands up to 70°C, ideal for environments with fluctuating temperatures.
- Grounding Integrity: Ensures proper earthing to prevent EMI interference in dense network racks.
Generic cables may lack the 16A rating required for Catalyst 9000 switches under full PoE++ load, risking circuit tripping or overheating.
Addressing Deployment Concerns
Q: Can this cable handle UK’s 230V power grids?
A: Yes. It’s rated for 250V AC, exceeding the UK standard voltage, ensuring safe operation even during minor surges.
Q: Is it compatible with UK power distribution units (PDUs)?
A: Absolutely. The BS 1363 plug fits standard UK PDUs and avoids adapter dependencies.
Q: Does it support Cisco StackPower or PowerStack?
A: While the cable itself doesn’t manage power stacking, it provides the stable current needed for these features to function reliably.
Practical Applications in UK Deployments
- Enterprise Offices: Securely powers Catalyst 9300 switches running VoIP and Wi-Fi 6 access points.
- Education Campuses: Supports high-density PoE++ for IP cameras, digital signage, and classroom devices.
- Data Centers: Integrates with Cisco UCS setups requiring UK-specific power infrastructure.

Final Assessment
The C9K-PWR-CAB-AC-UK= exemplifies Cisco’s commitment to regional customization. While some may dismiss it as “just a cable,” its role in preventing downtime caused by undervoltage or EMI cannot be overstated. For UK-based teams, pairing Catalyst 9000 switches with this purpose-built cable isn’t a luxury—it’s a non-negotiable safeguard for maintaining operational integrity in demanding environments.
