CAB-AC-2500W-ISRL=: How Does This 2500W Cable Solve Power Challenges in Cisco’s High-Density Deployments?



​Understanding the CAB-AC-2500W-ISRL=​

The ​​CAB-AC-2500W-ISRL=​​ is a Cisco-engineered 2500W AC power cable designed for high-density Catalyst 9000 series switches and Nexus data center platforms. Specifically tailored for environments requiring massive power throughput—such as AI/ML clusters, hyperscale data centers, or media rendering farms—this cable ensures stable, high-current delivery to hardware pushing performance boundaries.


​Critical Technical Specifications​

  • ​2500W Power Rating​​: Supports up to 2500W at 200-240V AC, enabling ​​Nexus 9300-GX​​ or ​​Catalyst 9600​​ switches to operate at full capacity without voltage drop.
  • ​Industrial-Grade Connectors​​: Features a C21 plug (device side) and C22 inlet (PDU/source) with gold-plated contacts to minimize resistance and arcing risks.
  • ​Certifications​​: Complies with ​​UL 62​​, ​​IEC 60320​​, and ​​CE​​ standards for fire safety, surge protection, and electromagnetic compatibility (EMC).
  • ​Operational Resilience​​: Rated for continuous use in ambient temperatures up to 70°C, with flame-retardant PVC insulation for hazardous environments.

​Why Generic Cables Can’t Handle 2500W Loads​

Third-party alternatives often fail catastrophically under 2500W demands due to:

  • ​Inadequate Conductor Size​​: Undersized copper wiring overheats, leading to insulation meltdowns or switch reboots.
  • ​Poor Contact Integrity​​: Cheap connectors degrade over time, increasing resistance and triggering thermal shutdowns.
  • ​Non-Compliance Risks​​: Lack of UL/CE certifications may violate insurance policies or regional electrical codes.

Cisco’s CAB-AC-2500W-ISRL= is precision-tested to sustain 2500W loads indefinitely, with redundant safety margins for peak operational reliability.


​Sourcing the CAB-AC-2500W-ISRL=​

For enterprises deploying mission-critical infrastructure, “CAB-AC-2500W-ISRL=” is available exclusively through itmall.sale. Benefits include:

  • ​Authenticity Guarantee​​: Direct Cisco supply chain access eliminates counterfeit risks.
  • ​Custom Lengths​​: Options from 3ft (rack-optimized) to 25ft (distributed power layouts).
  • ​Global Stock Availability​​: Pre-shipment testing and rapid delivery for urgent upgrades.

​A Reality Check from the Data Center Trenches​

During a recent deployment of Nexus 9300-GX switches for a generative AI startup, a contractor’s off-brand 2500W cable failed mid-training cycle, corrupting a $200K GPU cluster. After replacing all cables with CAB-AC-2500W-ISRL= units, the system ran flawlessly for 12 months—proving that in power-hungry setups, every link in the chain must be enterprise-grade. This cable isn’t an accessory; it’s the lifeline of high-performance infrastructure.
