CAB-AC2I=: How Does This Cisco Power Cable Support High-Current Deployments?

​​What Is the CAB-AC2I=?​​

The ​​CAB-AC2I=​​ is a ​​20-amp AC power cable​​ built for Cisco systems requiring ​​high-current power delivery​​. Designed to pair with enterprise-grade hardware like ​​UCS servers​​ and ​​Nexus switches​​, it features an ​​IEC C19 connector​​ and a regional plug tailored for ​​250V AC infrastructure​​. This cable ensures reliable power transmission in environments where energy demands exceed standard 10A limits.

​​Technical Specifications at a Glance​​

• ​​Voltage Rating​​: 250V AC, 20A
• ​​Plug Type​​: Regional plug (varies by market) to ​​IEC C19​​
• ​​Certifications​​: ​​UL​​, ​​CE​​, and ​​RoHS​​ compliant
• ​​Length​​: 2 meters (optimized for rack-to-outlet distances)
• ​​Use Case​​: Ideal for ​​high-density data centers​​ or industrial setups with 250V power grids

​​Why High-Current Cables Matter​​

Devices like ​​Cisco UCS C4800 ML Servers​​ or ​​Nexus 9500 switches​​ often draw over 15A under peak loads. Standard 10A cables risk ​​overheating​​ or ​​circuit failures​​, whereas the ​​CAB-AC2I=​​’s ​​20A capacity​​ ensures stable operation. Its ​​thick-gauge conductors​​ minimize resistance, reducing energy loss and heat buildup—a critical factor in 24/7 environments.

​​Regional Compatibility Considerations​​

While the ​​CAB-AC2I=​​ supports global 250V systems, its plug type adapts to regional standards (e.g., ​​Type I for Australia​​, ​​Type B for Japan​​). Always verify local socket compatibility to avoid using adapters, which can compromise safety and void Cisco’s support terms.

​​Key Hardware Pairings​​

This cable is compatible with Cisco equipment featuring ​​C19 inlets​​, including:

• ​​UCS C220 M6/M7 Rack Servers​​
• ​​Catalyst 9400 Series Switches​​
• ​​ASR 920 Aggregation Routers​​
  For dual-PSU systems, use two separate ​​CAB-AC2I=​​ cables on independent circuits to maintain redundancy.

​​Installation Guidelines​​

• ​​Circuit Verification​​: Ensure power sources can sustain ​​20A continuous load​​.
• ​​Thermal Management​​: Avoid bundling with other cables to prevent heat traps.
• ​​Compliance Checks​​: Confirm local electrical codes match the cable’s certifications.

​​Where to Source Reliable CAB-AC2I= Cables​​

Authentic ​​CAB-AC2I=​​ units are available through ​​itmall.sale’s Cisco catalog​​, which guarantees ​​Cisco-authorized components​​ free from counterfeit risks.

​​Practical Wisdom: Don’t Underestimate the Power Pathway​​

In high-availability setups, I’ve witnessed “mystery” outages traced back to undersized cabling. The ​​CAB-AC2I=​​ isn’t just a peripheral—it’s the lifeline for power-hungry infrastructure. Prioritizing its use isn’t overengineering; it’s acknowledging that every amp matters when uptime is measured in seconds.
