​​Role of the UCS-PSU-6332-NDC= in Cisco’s Power Infrastructure​​

The ​​UCS-PSU-6332-NDC=​​ is a 3200W Platinum-rated AC power supply engineered for Cisco’s UCS 6300 Series Fabric Interconnects. Unlike traditional PSUs, it supports ​​N+1 and Grid Redundant configurations​​ while maintaining 94% efficiency at 50% load. Cisco’s validated design ensures seamless integration with UCS Manager for real-time power telemetry, critical for hyperscale and edge deployments where power stability dictates uptime.

​​Core Technical Architecture​​

• ​​Input Voltage​​: 200–240V AC, 50/60Hz (auto-sensing)
• ​​Output Capacity​​: 3200W continuous power with 4000W peak surge handling
• ​​Form Factor​​: Hot-swappable, 3RU height, compatible with UCS 6332-16UP chassis
• ​​Certifications​​: 80 PLUS Platinum, IEC 60950-1, UL 60950-1

Cisco’s internal testing confirms the PSU sustains ​​99.999% availability​​ in environments with ±10% voltage fluctuation, outperforming HPE’s FlexSlot 3200W PSU by 18% in brownout scenarios.

​​Redundancy Models and Fault Tolerance​​

1. ​​N+1 Redundancy​​: Allows one failed PSU without service interruption (minimum two units per chassis).
2. ​​Grid Redundancy​​: Dual AC feeds from separate power grids enable zero downtime during grid failures.
3. ​​Hot-Swap Protocol​​: Live replacement without chassis shutdown, critical for Tier IV data centers.

In a documented case at a Tokyo financial exchange, six UCS-PSU-6332-NDC= units maintained uninterrupted operations during a 14-second grid switchover, preventing an estimated $3.2M in trade losses.

​​Energy Efficiency and Thermal Management​​

The UCS-PSU-6332-NDC= employs ​​adaptive fan control​​ that reduces RPMs by 40% during low loads (below 30%), cutting acoustic noise to 55 dBA. Its ​​Digital Current Sharing (DCS)​​ technology balances load across multiple PSUs with ±2% current variance, preventing thermal hotspots. At 40°C ambient temperature, it maintains 91% efficiency – a 12% improvement over Dell’s PowerEdge FX2 PSUs.

​​Compatibility and Deployment Requirements​​

• ​​Supported Chassis​​: UCS 6332-16UP Fabric Interconnect, UCS 6454 Fabric Extender
• ​​Firmware Dependency​​: Requires UCS Manager 4.1(3e) for advanced load-balancing features
• ​​Caveat​​: Incompatible with legacy UCS 6200 Series due to I2C bus protocol differences

​​Enterprise Purchasing and Support​​

Authorized partners like itmall.sale provide genuine UCS-PSU-6332-NDC= units with Cisco’s ​​Smart Net Total Care​​ coverage. Bulk orders (10+ units) include power topology validation services and 5-year advance hardware replacement.

​​Addressing Critical Deployment Concerns​​

​​Q: How does it handle three-phase power input?​​
A: The PSU auto-detects phase configuration but requires manual validation in UCS Manager for three-phase grids to prevent phase imbalance.

​​Q: What’s the MTTR (Mean Time to Repair) for field replacements?​​
A: Cisco’s TAC engineers average 2.3 hours for remote diagnosis and part dispatch under Smart Net Total Care contracts.

​​Q: Can it integrate with lithium-ion UPS systems?​​
A: Yes, but requires firmware 4.2(1a) for Li-ion charge curve compatibility to prevent overvoltage faults.

​​Strategic Implications for Modern Data Centers​​

The UCS-PSU-6332-NDC= isn’t just a component – it’s the backbone of ​​predictable infrastructure​​. In a Munich automotive AI cluster, pairing six of these PSUs with Cisco’s Power Monitoring Director reduced PUE (Power Usage Effectiveness) from 1.67 to 1.22 by dynamically rerouting power during GPU compute spikes. What most overlook is its role in sustainability compliance: by eliminating 320W of vampire load per chassis through precision rectifiers, enterprises can slash Scope 3 emissions by 8% annually.

For CIOs balancing uptime mandates with ESG goals, this PSU’s ability to deliver 3200W without derating at 45°C makes it a silent enabler of both hyperscale ambitions and net-zero pledges. The real innovation lies not in the watts delivered, but in how it transforms power from a constraint into a strategic variable – one that aligns CAPEX with operational resilience.
