Core Functionality & Design Philosophy

The ​​AIR-ACC15-AC-PLGS=​​ is a Cisco-certified ​​AC power shelf module​​ designed for Catalyst 9300/9500 series switches deployed in high-density enterprise networks. This 2U vertical power distribution unit enables ​​N+1 redundant power configurations​​ while maintaining thermal efficiency through perforated aluminum airflow channels optimized for 40°C ambient environments.

Key Technical Specifications

• ​​Load Capacity​​: Supports ​​3000W continuous power delivery​​ with 94% efficiency rating (80 Plus Platinum equivalent)
• ​​Voltage Flexibility​​: Auto-sensing 100-240V AC input with ±5% voltage tolerance for unstable grid conditions
• ​​Modular Design​​: Hot-swappable power trays compatible with Cisco ​​PWR-C4-3000ACV​​ and ​​PWR-C5-4200ACV​​ modules
• ​​Safety Compliance​​: Meets UL 60950-1 and NEBS Level 3 standards with integrated ground fault circuit interrupter (GFCI)

Critical User Concerns Addressed

​​Q: How does AIR-ACC15-AC-PLGS= differ from legacy models like PWR-3K-AC= in PoE++ deployments?​​

​​Q: Can it support mixed DC/AC power inputs in hybrid environments?​​
A: While optimized for AC configurations, its ​​dual-rectifier backplane​​ allows concurrent 48V DC input through Cisco ​​PWR-DC-3000-48​​ modules for hybrid power architectures.

​​Q: What thermal management innovations are included?​​

• ​​Variable Speed Fans​​: Automatically adjust from 35% to 100% duty cycle based on load/temperature
• ​​Zonal Isolation​​: Physically separates AC/DC conversion stages to prevent thermal crossover

Deployment Best Practices

1. ​​Data Center Racks​​: Maintain ≥1U vertical spacing between units in 42U cabinets exceeding 15kW total load
2. ​​Industrial IoT Deployments​​: Pair with Catalyst IE9300 Rugged switches using Class I Division 2 conduit kits
3. ​​Modular Power Scaling​​: Combine three units in parallel for ​​9kW total capacity​​ using Cisco StackPower v2 technology

Procurement & Validation

Engineering Perspective

The ​​AIR-ACC15-AC-PLGS=​​ redefines power infrastructure as an intelligent edge rather than passive hardware. While third-party PSUs may claim cost advantages, none achieve the ​​<0.5% current imbalance​​ critical for 802.3bt PoE++ deployments. For enterprises scaling AI-driven IoT networks, this module’s ability to maintain ±1°C thermal consistency under 80% load isn’t optional – it’s the foundation of predictable uptime in 24/7 mission-critical operations.
