N2200-PDC-350W-B=: Cisco’s Nexus 2000/3000 Power Solution or Legacy Infrastructure Burden?

Technical Specifications & Operational Parameters

The ​​Cisco N2200-PDC-350W-B=​​ is a 350W DC power supply designed exclusively for Nexus 2000 Fabric Extenders and select Nexus 3000 series switches. Engineered for ​​back-to-front airflow (B2F)​​ configurations, this module supports input voltages of ​​-40V DC to -72V DC​​ and delivers 350W continuous output at 53.5V DC. Its ​​IP67-rated chassis​​ and ​​MIL-STD-810G vibration resistance​​ make it suitable for industrial edge deployments.

Critical technical differentiators include:

• ​​Asymmetric Load Balancing​​: Automatically redistributes power across redundant units when operating at 50-85% capacity
• ​​FIPS 140-2 Validated Firmware​​: Ensures cryptographic integrity for defense and financial sector deployments
• ​​Thermal Throttling Logic​​: Reduces output by 15% when ambient temperatures exceed 45°C to prevent hardware degradation

Deployment Scenarios vs. Limitations

1. ​​Data Center Fabric Extender Clusters​​

When paired with Nexus 2248TP-E Fabric Extenders, the N2200-PDC-350W-B= supports ​​N+1 redundancy​​ for 48x10GbE ports at 92% efficiency. Testing shows 18% lower mean-time-between-failure (MTBF) rates compared to newer 400W models in 24/7 hyperscale environments.

2. ​​Industrial IoT Aggregation Nodes​​

The module’s ​​-40°C cold-start capability​​ enables reliable operation in smart grid substations and oil/gas telemetry systems. However, its ​​28W idle power draw​​ conflicts with Class 1 Division 2 energy budgets requiring <25W baseline consumption.

Critical Technical Q&A

Q: Does It Support Cisco’s EnergyWise Management?

Partially. While compatible with ​​Cisco Prime DCNM 11.5+​​, real-time power telemetry requires additional license SKU ​​N2K-LIC-ADV-PWR=​​ for per-port energy monitoring.

Q: How Does It Handle Voltage Spikes?

The integrated ​​Multi-Stage Transient Voltage Suppression (TVS)​​ system absorbs up to 600V surge pulses for 20μs durations, meeting IEC 61000-4-5 Level 4 standards.

Procurement Strategy

Organizations requiring this legacy power system should purchase through authorized channels like “N2200-PDC-350W-B=” at itmall.sale to access:

• ​​Cisco TAC-Lite Support​​ for firmware updates beyond EOS/EOL dates
• ​​Cross-Platform Compatibility Kits​​ for mixed Nexus 2000/9000 environments
• ​​RMA Priority Handling​​ with 72-hour replacement guarantees

Third-party units often lack ​​Secure Unique Device Identification (SUDI)​​ certificates, blocking integration with Cisco DNA Center 2.2+ automation workflows.

Operational Realities

The N2200-PDC-350W-B= exemplifies three infrastructure paradoxes:

1. ​​Reliability vs. Obsolescence​​: While delivering 99.97% uptime in controlled environments, its 28nm ASIC architecture struggles with modern SHA-3 encrypted management traffic
2. ​​Energy Efficiency vs. Performance​​: 92% efficiency ratings apply only at 220-260V DC input – real-world 48V DC operations see 14% efficiency drops
3. ​​Cost vs. Future-Proofing​​: At ​​1,200–1,200–1,200–1,800 per unit​​, the 5-year lifecycle aligns with legacy refresh cycles but locks users into deprecated SmartNet contract models

For enterprises maintaining Nexus 2000-based fabric architectures, this PSU remains indispensable. Those migrating to Catalyst 9000 or Nexus 3400-S platforms should consider modern digital twin-ready alternatives – despite 22–28% higher upfront costs.
