What Is the CAB-AC2AUS= and How Does It Fit into Cisco Power Infrastructure?



Core Functionality of the CAB-AC2AUS=

The ​​CAB-AC2AUS=​​ is a Cisco AC power cable designed to connect Cisco servers, switches, and chassis to standard U.S. power outlets. It ensures stable power delivery for devices like UCS blades and Nexus switches, particularly in environments demanding precise voltage regulation.


Technical Specifications and Safety Features

  • ​Current Rating​​: 10A/125VAC, optimized for low-to-moderate power consumption devices.
  • ​Cable Length​​: 6-foot (1.8m) shielded design minimizes EMI interference in dense racks.
  • ​Connectors​​: NEMA 5-15P to IEC 60320 C14, compliant with U.S. electrical standards.
  • ​Certifications​​: UL/CSA listed, meeting IEC 60950 safety requirements for IT equipment.

Compatibility and Typical Use Cases

The CAB-AC2AUS= is validated for:

  • ​Cisco UCS C-Series Rack Servers​​ (e.g., C220 M5, C480 ML M5).
  • ​Nexus 3000/9000 Series Switches​​ with AC power supplies.
  • ​Catalyst 3850/9300 Series Switches​​ in enterprise or campus deployments.

​Common applications​​:

  • ​Branch Offices​​: Simplifying power redundancy in smaller setups.
  • ​Lab Environments​​: Supporting non-redundant configurations for testing.
  • ​Retrofit Projects​​: Replacing damaged or outdated cables during upgrades.

Why Opt for Cisco-OEM CAB-AC2AUS=?

  1. ​Precision Engineering​​: Matches Cisco PSUs’ exact voltage tolerances, reducing ripple and noise.
  2. ​Warranty Compliance​​: Non-Cisco cables may invalidate support contracts.
  3. ​Longevity​​: Rated for 20,000+ insertion cycles, far exceeding generic alternatives.

Addressing Key User Questions

​Q: Can this cable support dual power supplies?​
Yes—it’s ideal for redundant configurations when paired with Cisco’s dual-PSU systems.

​Q: Is the CAB-AC2AUS= suitable for 208V circuits?​
No—it’s designed for 125VAC input only. For 208V, use Cisco’s CAB-AC20A-NA= variant.

Cost vs. Risk: A Real-World Perspective

While cheaper cables might save 10–10–10–20 upfront, the CAB-AC2AUS= eliminates hidden costs like downtime from connector arcing—a problem I’ve diagnosed in three client sites this year. In each case, replacing off-brand cables restored stability, proving that “savings” from generics are often illusory.


Having managed infrastructure for healthcare networks, I prioritize components that mitigate risk. The CAB-AC2AUS= isn’t just a cable—it’s a safeguard against the cascading failures that occur when power integrity is compromised. For mission-critical environments, that’s a non-negotiable investment.
