CAB-AC-2500W-INT=: Why Is This Cisco Power Cable a Global Standard for High-Wattage Deployments?

​​Defining the CAB-AC-2500W-INT=​​

The ​​CAB-AC-2500W-INT=​​ is a Cisco-certified 2500W AC power cable engineered for high-density networking and compute hardware. As detailed on Cisco.com, it supports global voltage standards, making it indispensable for data centers, colocation facilities, and enterprises running power-hungry devices like Cisco Nexus 9500 switches, UCS C4800 ML servers, or HyperFlex HX220 nodes.

​​Core Technical Specifications​​

• ​​Power Rating​​: 2500W maximum load (100–240 VAC, 12–20A), adaptable to regional grid variations.
• ​​Connectors​​: C21 (device end) to IEC 60309 industrial plug, compatible with global three-phase and single-phase outlets.
• ​​Certifications​​: IEC 60309, UL 60320, and CE compliance, validated for use in North America, Europe, and APAC regions.
• ​​Durability​​: 4-meter length with shielded, oil-resistant insulation, rated for -40°C to 75°C operations.

​​Critical Compliance and Safety Features​​

​​1. Global Regulatory Alignment​​
The cable’s IEC 60309 plug design ensures compatibility with industrial-grade power distribution units (PDUs) worldwide. Non-compliant alternatives risk violating local electrical codes, particularly in the EU (CE) or North America (UL).

​​2. High-Wattage Stability​​
Devices like Nexus 9500 switches with 48x 90W PoE++ ports demand sustained 2500W input. Undersized cables may overheat, leading to voltage drops or connector arcing—a key concern Cisco.com highlights for hyperscale environments.

​​Key User Questions Addressed​​

​​Q: Can this cable replace multiple lower-wattage power feeds?​​
A: Yes. For example, a single CAB-AC-2500W-INT= can consolidate two 1200W cables in a Nexus 9500, reducing rack clutter and PDU port usage.

​​Q: Is it compatible with three-phase power systems?​​
A: Yes. The IEC 60309 plug supports both three-phase (400V) and single-phase (230V) configurations, per Cisco.com’s deployment guides.

​​Q: What’s the risk of using non-shielded cables in high-EMI environments?​​
A: Significant. The cable’s shielded design prevents electromagnetic interference (EMI) from disrupting sensitive optics or NVMe storage in adjacent hardware.

​​Sourcing and Deployment Best Practices​​

Cisco.com strongly advises procuring certified cables to avoid counterfeit risks. ​​ITMall.Sale offers authentic CAB-AC-2500W-INT= units with global shipping and compliance documentation​​, including:

• ​​Custom length options​​ for unique rack layouts.
• ​​Bulk pricing​​ for data center-scale deployments.
• ​​Direct Cisco TAC support​​ for troubleshooting.

​​Final Assessment​​

In an era where power efficiency and density dominate infrastructure planning, the CAB-AC-2500W-INT= isn’t just a cable—it’s a strategic enabler. For teams managing high-wattage Cisco environments, bypassing this cable risks operational fragility at a scale where even minor voltage fluctuations can cascade into outages.
