CAB-AC-30A-US1=: How Does It Power Cisco’s Most Demanding U.S. Deployments?

​​What Is the CAB-AC-30A-US1=?​​

The ​​CAB-AC-30A-US1=​​ is a Cisco-certified 30A AC power cable designed for high-density, power-intensive Cisco hardware in the U.S. market. As stated on Cisco.com, this cable supports ultra-high-performance devices like Nexus 9500 switches, UCS C4800 ML servers, and Catalyst 9600 Series switches, ensuring stable power delivery in data centers and enterprise environments.

​​Technical Specifications and Compliance​​

• ​​Voltage Rating​​: 208–240 VAC, 60 Hz, optimized for U.S. three-phase power systems.
• ​​Connectors​​: C21 (device end) to NEMA L15-30P twist-lock plug, ensuring secure connections in high-vibration environments.
• ​​Certifications​​: UL 60320, NEC compliance, and Cisco’s internal validation for 30A continuous loads.
• ​​Durability​​: 4-meter length with industrial-grade insulation, rated for -40°C to 75°C and 90% humidity.

​​Why the CAB-AC-30A-US1= Is Irreplaceable​​

​​1. High-Current Support for Critical Hardware​​
Devices like Nexus 9500 switches with 100G/400G uplinks or UCS servers running AI workloads require 30A input. Lower-rated cables (e.g., 20A) risk tripping circuits or causing thermal failures under sustained loads.

​​2. Regulatory Compliance​​
U.S. electrical codes mandate NEMA L15-30P connectors for three-phase 30A circuits. Non-compliant cables may fail inspections or void Cisco’s hardware warranties.

​​Key User Questions Addressed​​

​​Q: Can I use this cable with single-phase power systems?​​
A: No. The NEMA L15-30P plug is designed for three-phase 208–240V systems. For single-phase 30A needs, refer to Cisco.com’s CAB-AC-30A-US2= documentation.

​​Q: Is it backward-compatible with older Nexus 7000 switches?​​
A: Only if the device supports C21/C22 inlets. Cisco.com advises verifying compatibility via their Power Supply Calculator tool.

​​Q: How critical is twist-lock design in data centers?​​
A: Essential. The twist-lock plug prevents accidental disconnections in environments with heavy cable management or airflow systems.
