​​Technical Specifications and Regional Compliance​​

The ​​Cisco CAB-1900W-UK-A1K=​​ is a ​​heavy-duty AC power cable​​ designed to pair with Cisco’s high-wattage power supply units (PSUs), such as the ​​C9K-PWR-1900WAC-R​​. Tailored for the UK market, it includes:

• ​​UK plug (BS 1363)​​ compliant with British electrical standards.
• ​​250V/16A rating​​ to safely deliver 1900W of power to Cisco chassis and switches.
• ​​3-meter length​​ for flexible rack installations, reducing strain on PSUs.
• ​​UL, CE, and RoHS certifications​​, ensuring safety and environmental compliance in enterprise environments.

This cable is critical for powering Cisco’s high-density Catalyst 9500/9600 switches and UCS servers in data centers requiring ​​uninterrupted, high-current AC power​​.

​​Key Features and Operational Impact​​

​​Why Use the CAB-1900W-UK-A1K=?​​

• ​​High Power Capacity​​: Supports energy-hungry devices like full-population Catalyst 9600 chassis with 400G line cards.
• ​​Safety Assurance​​: Reinforced insulation and grounded connectors prevent overheating and electrical hazards.
• ​​Compliance​​: Avoids regulatory risks in UK facilities by adhering to ​​BS 7671 wiring regulations​​ and ​​The Plugs and Sockets Safety Regulations 1994​​.

​​Critical User Questions Answered​​

​​Q: Which Cisco devices require this specific cable?​​
Primarily ​​1900W AC PSUs​​ (e.g., C9K-PWR-1900WAC-R) used in Catalyst 9500/9600 switches and select UCS servers.

​​Q: Can it be used in other regions with adapters?​​
Cisco discourages adapters due to voltage mismatches. For non-UK deployments, use region-specific variants (e.g., ​​CAB-1900W-US-A1K=​​ for the US).

​​Q: Is it backward-compatible with lower-wattage PSUs?​​
Yes, but oversizing the cable offers no operational benefit and may increase rack clutter.

​​Procurement and Authenticity​​

While Cisco.com outlines technical requirements, UK-based enterprises should source the ​​CAB-1900W-UK-A1K=​​ through authorized channels like [“CAB-1900W-UK-A1K=” link to (https://itmall.sale/product-category/cisco/). This guarantees compliance with UK safety laws and preserves warranties, which third-party cables often invalidate.

​​Deployment Considerations​​

The ​​CAB-1900W-UK-A1K=​​ is non-negotiable for UK organizations running power-intensive Cisco infrastructure. While its specifications might seem excessive for smaller setups, they’re vital for avoiding voltage drops or circuit tripping in high-load scenarios. For multinational firms, regional variants of this cable simplify compliance but demand careful inventory management. Procuring counterfeit alternatives—however cost-effective—risks costly downtime, equipment damage, or even fire hazards. Always prioritize certified suppliers, especially when powering mission-critical hardware where reliability isn’t just preferable but mandatory.
