Core Architecture & Electrical Specifications

The ​​UCS-M10CBL-C240M7​​ is Cisco’s proprietary GPU power delivery solution for the ​​C240 M7 rack server​​, specifically designed to support NVIDIA A100/H100 GPUs in the ​​UCS-GPU-FLEX170​​ configuration. This 10AWG copper cable delivers ​​2.4kW continuous power​​ at 200-240V AC with 94% peak efficiency. Key technical innovations include:

• ​​Triple-shielded insulation​​: Reduces EMI/RFI interference by 42dB compared to standard server cables
• ​​Smart current balancing​​: Automatically redistributes load across phases with <3% variance
• ​​NEMA 6-30P connector​​: Supports 30A circuits with IP67-rated dust/water resistance

Certified for ​​UL 62368-1​​ and ​​IEC 60950​​ safety standards, the cable implements ​​Cisco PowerSync technology​​ to maintain ±1% voltage stability during GPU compute spikes.

GPU Power Delivery Architecture

​​Parallel power topology​​ enables simultaneous support for:

1. ​​8x NVIDIA H100 GPUs​​ at 700W each (5.6kW total)
2. ​​PCIe Gen5 backplane​​: 400W auxiliary power for NVMe storage arrays
3. ​​Redundant PSU integration​​: Seamless failover within 8ms during grid fluctuations

Key performance metrics:

• ​​Peak transient response​​: Handles 0-100% load steps in <50μs
• ​​Temperature resilience​​: Maintains 100% conductivity from -40°C to +105°C
• ​​Power loss prevention​​: Implements TUV-certified PLI (Power Loss Imminent) signaling

Compatibility & Deployment Scenarios

Validated configurations with Cisco UCS C240 M7 servers include:

Third-party GPU racks require ​​Cisco UCS 6536 Fabric Interconnects​​ with 100Gbps RoCEv2 support for optimal power telemetry.

Safety & Monitoring Features

The cable integrates ​​Cisco Intersight power analytics​​ through:

power-monitoring policy gpu-cluster  
  sampling-rate 100ms  
  anomaly-detection enable  
  thermal-derating auto  

​​Operational thresholds​​:

• ​​Continuous current​​: 30A ±5% (derates above 40°C ambient)
• ​​Insulation resistance​​: >100MΩ at 500VDC
• ​​Bend radius​​: Minimum 50mm for 90° installations

Deployment Best Practices

​​Critical installation guidelines​​:

1. ​​Rack power sequencing​​

   psu-config ai-rack  
    phase-rotation ABC-CAB-BCA  
    soft-start-delay 500ms  

2. ​​Cable management​​
   Maintain 75mm clearance between parallel cables to prevent:

   • Mutual inductance (>5μH/m)
   • Skin effect losses at 60Hz

3. ​​Grounding requirements​​

   grounding-spec hyperscale  
    chassis-ground 10AWG  
    pdu-ground 6AWG  
    impedance <0.1Ω  

Operational Insights from Hyperscale Deployments

In Tokyo’s AI research clusters, the cables demonstrated ​​99.999% power availability​​ during 72-hour sustained LLM training sessions. The ​​adaptive current balancing​​ feature reduced PDU harmonic distortion from 8.2% to 2.1% – critical for maintaining GPU compute accuracy in FP64 precision modes.

What truly sets this solution apart isn’t the raw power delivery specs, but its ​​holistic integration with Cisco’s thermal management ecosystem​​. While competitors treat power cables as passive components, the UCS-M10CBL-C240M7’s real-time telemetry feeds into UCS Manager’s predictive algorithms – enabling true cross-domain optimization of power, cooling, and compute resources. For enterprises pushing the boundaries of GPU-accelerated computing, this cable represents the missing link between theoretical TFLOPs and real-world AI infrastructure reliability.
