What Is the CAB-ACC= and How Does It Optimize Cisco Power Delivery?

Core Role of the CAB-ACC=

The ​​CAB-ACC=​​ is a Cisco AC power cable assembly designed to connect Cisco chassis and switches to standard power sources. It serves as a critical interface for devices requiring stable, high-quality power in enterprise and data center environments.

Key Technical Specifications

• ​​Voltage/Current​​: 10A/250VAC, supporting global single-phase power systems.
• ​​Length​​: 2 meters (6.5 feet), balancing flexibility and clutter reduction in racks.
• ​​Connectors​​: IEC 60320 C14 (device end) to C13 (power source), standardized for compatibility.
• ​​Certifications​​: UL, CE, and CSA listed, ensuring compliance with international safety standards.

Compatibility and Deployment Scenarios

The CAB-ACC= is validated for use with:

• ​​Cisco UCS C-Series Rack Servers​​ (e.g., C240 M5, C480 ML M5).
• ​​Nexus 5600/9300 Series Switches​​ with AC power supplies.
• ​​ASR 9000 Series Routers​​ in telecom or ISP deployments.

​​Typical use cases​​:

• ​​Data Centers​​: Powering high-availability clusters with redundant PSU configurations.
• ​​Hybrid Clouds​​: Simplifying cable management in multi-vendor environments.
• ​​Remote Offices​​: Ensuring reliable power for edge networking devices.

Why Use Cisco-Genuine CAB-ACC=?

1. ​​Precision Engineering​​: Matches Cisco hardware’s exact voltage tolerances, minimizing power fluctuations.
2. ​​Durability​​: Reinforced shielding resists EMI/RFI interference in electrically noisy environments.
3. ​​Warranty Assurance​​: Third-party cables risk voiding Cisco Smart Net or service contracts.

Addressing Critical User Questions

​​Q: Can this cable handle 200–240V input?​​
Yes—its 250VAC rating accommodates most global single-phase grids, but always verify local voltage standards.

​​Q: Is the CAB-ACC= backward-compatible with older Cisco switches?​​
Only if the device uses an IEC C14 inlet. For example, it works with Nexus 5548UP switches but not Catalyst 3750-X models (which require C15 connectors).

Cost Efficiency vs. Hidden Risks

While generic cables cost 30–50% less, the CAB-ACC= eliminates risks like connector melting under sustained load—a failure I’ve witnessed in colocation facilities using uncertified parts. One outage from a $15 cable can cost thousands in downtime, making OEM components a prudent long-term investment.

After troubleshooting power-related failures in financial sector networks, I’ve grown adamant about using Cisco-certified cables. The CAB-ACC= isn’t just a peripheral—it’s the lifeline ensuring uptime for revenue-critical infrastructure. Cutting corners here is a gamble no operations team should take.
