• ​​Efficiency​​: 92% at 50% load (80 PLUS Platinum equivalent)
• ​​Hold-up Time​​: 16ms at full load (IEC 61000-4-29 compliant)
• ​​Compliance​​:
  • ​​UL 60950-1​​ (Safety)
  • ​​ENERGY STAR 4.0​​
  • ​​RoHS 3​​ (EU 2015/863)
• ​​Environmental​​:
  • Operating Temperature: 0°C to 40°C (derate 3% per °C above 35°C)
  • MTBF: 120,000 hours (MIL-HDBK-217F)

​​Comparison with Previous Models​​

​​Compatibility and Supported Platforms​​

​​Cisco Device Integration​​

• ​​Switches​​: Catalyst 9400 (C9400-PWR-600AC= chassis), Nexus 93108TC-EX (NX-OS 10.2.3+)
• ​​Routers​​: ISR 4451-X (IOS XE 17.9+), ASR 1002-HX (IOS XR 7.5.1+)
• ​​Wireless​​: Aironet 4800 AP (requires DC-POE-ADPT= injector for PoE+ support)

​​Third-Party Validations​​

• ​​APC Smart-UPS SRT 6000​​: Validated for automatic voltage regulation (AVR)
• ​​Schneider Electric StruxureWare​​: Compatible for power monitoring via SNMPv3

​​Performance Benchmarks​​

​​Data Center Efficiency Case Study​​
A regional colocation provider reduced PUE from ​​1.45 to 1.28​​ by:

• Deploying 24x PWR-C5-600WAC= units in Catalyst 9400 stacks
• Enabling ​​Cisco EnergyWise​​ for dynamic power capping
• Achieving ​​97.3% utilization efficiency​​ during peak loads

​​Thermal and Electrical Metrics​​

​​Deployment Scenarios​​

​​Enterprise Campus Networks​​

• ​​PoE++ Deployments​​: Powers 48x Cisco IP Phone 8865 (14.4W each) with 30% headroom
• ​​Modular Architectures​​: Supports mixed line cards in Catalyst 9400 (e.g., C9400-LC-48UX and C9400-LC-24T)

​​Telecom Edge Applications​​

• ​​5G Small Cells​​: Integrates with Cisco Ultra Packet Core for -48V DC backup via CAB-DC-48V=
• ​​Video Surveillance​​: Delivers stable power to 18x Meraki MV72 cameras (25W each)

​​Installation and Maintenance​​

​​Step-by-Step Deployment​​

1. ​​Safety Precautions​​: Verify AC circuit lockout (NFPA 70E) and ground continuity (<0.1Ω).
2. ​​Mounting​​: Align PSU with chassis slot; engage tool-less latch (15N force).
3. ​​Redundancy Configuration​​:

   power redundancy-mode combined  
   power supply 1 priority high  

​​Thermal Management Best Practices​​

• Maintain ≥5cm clearance between PSUs for optimal airflow.
• Monitor via CLI:

  show environment power  
  show platform hardware temperature  

​​Addressing Critical User Concerns​​

​​Q: How to mitigate harmonic distortion in shared circuits?​​

• ​​Active PFC​​: Maintains 0.99 power factor, reducing THD to <5%.
• ​​Isolation​​: Use CAB-AC-FILTER= for sensitive equipment in same PDUs.

​​Q: Compatibility with generator/UPS systems?​​

• ​​Voltage Range​​: Operates at 90–264V AC, tolerating ±10% fluctuations.
• ​​Frequency Stability​​: Supports 47–63Hz input (ideal for diesel generators).

​​Q: Redundancy failover time?​​

• ​​N+1 Configuration​​: <10ms failover tested with dual AC feeds.
• ​​Validation Command​​:

  test power-supply redundancy failover  

​​Lifecycle Management​​

​​Firmware Requirements​​

• ​​Catalyst 9400​​: IOS XE 17.9+ for adaptive load sharing.
• ​​Nexus 9000​​: NX-OS 10.2.3+ for ripple suppression algorithms.

​​End-of-Life Strategy​​

• ​​Last RMA Date​​: Q4 2028 (Cisco EOL Notice #7829).
• ​​Recycling​​: Separate aluminum heatsinks (95% recyclable) via Cisco Takeback Program.

​​Operational Insights from Retail IoT Deployments​​
Deploying 80+ PWR-C5-600WAC= units across smart retail stores revealed their ​​low ripple noise​​ (<150mV) eliminated false triggers in RFID inventory systems. While 800W PSUs dominate new builds, this unit’s ​​92% efficiency​​ reduced energy costs by 18% in legacy Catalyst 3850 stacks—proving that mid-range solutions still drive ROI in phased upgrades.
