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.
