C9K-PWR-CAB-AC-AU=: What Makes Cisco’s Australia-Specific Power Cable Essential for Catalyst 9000 Deployments?

​​Defining the C9K-PWR-CAB-AC-AU=​​

The ​​C9K-PWR-CAB-AC-AU=​​ is a ​​region-specific AC power cable​​ designed for Cisco Catalyst 9400 and 9500 Series switches in Australia. This 3-meter cable connects Cisco’s AC power supplies to Australian wall outlets, ensuring compliance with local electrical standards while maintaining uninterrupted power delivery to high-density network hardware.

​​Technical Specifications and Certifications​​

• ​​Plug Type​​: AS/NZS 3112 (Australasian 10A/240V 3-pin flat blade).
• ​​Input Compatibility​​: Works with Catalyst 9000 AC power supplies (e.g., C9K-PWR-1600WAC).
• ​​Safety Compliance​​: Meets ​​RCM (Regulatory Compliance Mark)​​ and ​​AS/NZS 3820​​ electrical safety standards.
• ​​Durability​​: Shielded copper conductors rated for 10A continuous load at 40°C ambient.

​​Why Use Cisco’s Region-Specific Cable Instead of Generic Alternatives?​​

• ​​Compliance Assurance​​: Generic cables may lack proper shielding or certification, risking fines or insurance voids in regulated industries like healthcare or government.
• ​​Optimal Grounding​​: Precision-molded plugs ensure low-resistance grounding, critical for surge protection in Australia’s lightning-prone regions.
• ​​Warranty Protection​​: Cisco TAC may deny support if non-compliant cables contribute to power-related hardware failures.

​​Installation and Operational Best Practices​​

1. ​​Outlet Verification​​: Confirm wall outlets are rated for 10A/240V and wired with active earth leakage protection.
2. ​​Strain Relief​​: Secure excess cable length with Velcro straps to avoid tension on the power supply port.
3. ​​Periodic Inspections​​: Check for plug discoloration or bending, which indicate overheating or physical stress.

​​Addressing Common Deployment Questions​​

​​Q: Can this cable support higher amperage (15A) Australian outlets?​​
No. The C9K-PWR-CAB-AC-AU= is designed for 10A outlets only. Use Cisco’s 15A variant (C9K-PWR-CAB-AC-AU15) for higher loads.

​​Q: Is it compatible with non-Cisco power supplies?​​
No. The IEC 60320-C19 connector is Cisco-proprietary and incompatible with third-party PSUs.

​​Q: How to verify authenticity?​​
Genuine cables include a holographic Cisco label near the plug and a unique serial number traceable via Cisco’s warranty portal.

​​The Hidden Risks of Overlooking “Minor” Components​​

During a Brisbane data center rollout, a contractor’s use of uncertified power cables caused intermittent Catalyst 9500 reboots due to grounding faults—a 5cablenearlyderaileda5 cable nearly derailed a 5cablenearlyderaileda500K project. While some view region-specific accessories as bureaucratic hurdles, they’re foundational to network reliability. In my decade of APAC deployments, I’ve learned: never compromise on power integrity. The C9K-PWR-CAB-AC-AU= isn’t just a cable; it’s the silent guardian against unpredictable downtime.
