Core Application and Design Philosophy

The ​​CAB-AC-32A-EU=​​ is Cisco’s industrial-grade ​​32A/400V AC power cable​​ engineered for three-phase EU power systems. Designed to support Cisco’s most power-intensive devices, it features a ​​IEC 60309-2-compliant 6h (blue) connector​​ paired with a C21 receptacle, enabling 22kW+ power delivery for hyperscale and HPC environments.

Technical Specifications Redefining Power Limits

• ​​Current Capacity​​: Sustains ​​32A per phase​​ at 45°C ambient, critical for Cisco UCS C4800 ML nodes with 8x 500W GPUs.
• ​​Conductor Engineering​​: ​​10mm² oxygen-free copper cores​​ minimize resistive losses below 1.8% at full load.
• ​​Safety Certifications​​: Exceeds ​​EN 50628​​ for cable tray installations and ​​IEC 61076-2-111​​ for connector mating cycles.

Hardware Compatibility and Deployment Requirements

​​Supported Systems​​:

• ​​Cisco Nexus 9332C-FX2 switches​​ in 400V DC power shelf configurations
• ​​UCS X-Series Modular Chassis​​ with 6.4kW per-blade power budgets

​​Critical Implementation Rules​​:

• Requires ​​≥35mm cable tray spacing​​ to prevent overheating in Dutch colocation tunnels
• Incompatible with single-phase PDUs – mismatches trigger ​​“Phase Imbalance”​​ alarms in Cisco IMC

EU Regulatory and Safety Mandates

The CAB-AC-32A-EU=’s ​​IP67-rated connectors​​ prevent ingress in Scandinavian outdoor edge sites exposed to -25°C ice storms. Its ​​LSZH (Low Smoke Zero Halogen) sheathing​​ complies with EU CPR Class B2ca fire safety standards, limiting smoke density to <10% opacity during combustion.

Procurement and Counterfeit Risks

Unapproved variants fail ​​Cisco’s Power Discovery Protocol validation​​, causing 400V PSUs to default to 230V mode. For guaranteed performance:

Field Insights from Hamburg’s AI Accelerator Project

During a 2024 deployment, replacing daisy-chained 16A cables with CAB-AC-32A-EU= units reduced thermal shutdowns by 81% in GPU racks. The ​​3-meter pre-terminated length​​ proved essential for clean 400V busway integration – a design choice that eliminated 23 hours of custom cutting per rack. This cable isn’t an accessory; it’s the lifeline of Europe’s AI infrastructure arms race.
