Hardware Compatibility

Important Restrictions:

1. This high-power PSU is designed for chassis deployments requiring large PoE power budgets.
2. Vacant power supply slots must be fitted with official Cisco filler panels to guarantee chassis airflow, thermal balance and EMC compliance.
3. Not compatible with Catalyst 9000, Catalyst 3850 or other non-C4500-E modular switch platforms.
4. Cisco recommends deploying identical PSU models for redundant configurations.
   Matching secondary redundant variant:PWR-C45-2800ACV/2.

Key Features & Benefits

1. Hot-swappable OIR capability: Enables live PSU replacement without complete chassis power shutdown to reduce maintenance downtime.
2. High-capacity integrated PoE support to power large volumes of VoIP phones, wireless access points and IP surveillance cameras.
3. Dual operation modes: Redundant mode for fault tolerance, combined load-sharing mode to maximize available power budget.
4. Active power factor correction minimizes power harmonic distortion and improves energy efficiency.
5. Real-time power health monitoring, fault logging and alert reporting via Cisco IOS CLI and SNMP.
6. Carrier-grade robust mechanical design for stable continuous long-term operation in wiring closets and data centers.
7. Optimized solution for fully populated Catalyst 4500-E chassis with multiple PoE linecards.

Typical Deployment Scenarios

Compliance & Certification

Important Note

PWR-C45-2800ACV = primary 2800W AC power supply (Supports system power + high-density PoE)

PWR-C45-2800ACV/2 = secondary redundant AC variant with identical electrical and mechanical specifications for dual redundant setups.
