UCS-PSU-6536-AC-D=: High-Capacity AC Power Supply for Cisco UCS 6536 Fabric Interconnect Systems

Core Architecture & Operational Specifications

The ​​UCS-PSU-6536-AC-D=​​ is Cisco’s 3000W AC power supply module designed for UCS 6536 Fabric Interconnects, engineered to support mission-critical AI/ML workloads and hyperconverged infrastructure. Built with ​​96% Platinum-rated efficiency​​, this hot-swappable PSU operates at 200-240V AC input and delivers ​​57.7A continuous current​​ at 52V DC output. Key technical innovations include:

• ​​Adaptive phase-balancing​​: Automatically redistributes load across three input phases with ±1% current imbalance tolerance
• ​​Hybrid cooling system​​: Combines dual counter-rotating fans with liquid-assisted heat pipes for 45°C ambient operation
• ​​Cryptographic power validation​​: Implements FIPS 140-3 Level 2 compliant signature verification for firmware updates

Certified for ​​NEBS Level 3+​​ and ​​MIL-STD-901D shock resistance​​, the module supports N+1/N+N redundancy configurations with <5ms failover latency.

Performance Benchmarks & Energy Efficiency

​​Validated metrics​​ in hyperscale AI clusters demonstrate:

1. ​​Power Factor Correction​​

   • ​​0.99+ PF​​ across 20%-100% load range
   • ​​<2% THD​​ at full load with harmonic mitigation

2. ​​Transient Response​​

   • ​​50μs recovery time​​ for 50%-75%-50% load steps
   • ​​1% overshoot​​ during 90% instantaneous load changes

3. ​​Thermal Management​​

   • ​​22dB(A) noise levels​​ at 40% load with eco-mode enabled
   • ​​5°C component temperature reduction​​ compared to previous-gen PSUs

Operational Insights from Financial HFT Deployments

In Tokyo’s high-frequency trading infrastructure, ​​adaptive phase-balancing​​ reduced transformer losses by 18% during peak market hours. The ​​cryptographic validation​​ system prevented 3 firmware tampering attempts during 2024 security audits.

What truly differentiates this PSU isn’t its raw power density, but its ​​holistic integration with Cisco’s EnergyWise management framework​​. While competitors focus on standalone efficiency metrics, the UCS-PSU-6536-AC-D=’s ability to coordinate power delivery across 64+ chassis through predictive load forecasting algorithms redefines data center power economics. The convergence of military-grade durability and AI-driven efficiency optimization proves that next-generation power infrastructure must solve the paradox of energy sustainability versus computational demand in hyperscale environments.
