Cisco PWR-C45-9000AC (PWR-C45-9000ACV) Full English Description

Product Overview

Key Features

1. 9000W Maximum Total Power Output with Triple AC Input Design
   Equipped with three independent AC input ports. The available output power varies according to the quantity of connected power feeds and input voltage. When all three inputs connect to high-line AC sources, the module achieves full 9000W capacity, supporting up to7500W dedicated PoE power budget. Flexible power allocation balances system base power and inline PoE loads.
2. Universal Wide-Range AC Input with Active PFC
   Auto-ranging input supports global power grid deployment, built-in active Power Factor Correction reaching ≥0.99 power factor to reduce harmonic distortion and improve energy efficiency.
   • Low line: 85 VAC ~ 132 VAC
   • High line: 170 VAC ~ 264 VAC
   • Operating frequency: 50Hz / 60Hz
   • Interface: Three IEC C19 AC power connectors
3. Hot-Swappable Field-Replaceable Design
   Supports online insertion and removal. Technicians can replace or add power modules without shutting down the Catalyst 4500 chassis, enabling non-disruptive maintenance and minimizing network outage risks.
4. Comprehensive Real-Time Monitoring & Telemetry
   Front-panel LED indicators individually display status for each of the three AC inputs, fan operation, output health and PoE status. The module transmits temperature, fault alarms and power consumption data to the supervisor engine through the chassis backplane.
5. Multi-Layer Hardware Protection
   Integrated overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short-circuit protection to protect both the power supply unit and the host switch chassis.
6. Redundancy & Load Sharing Support
   Multiple identical power supplies can be installed inside the chassis to implement N+1 or 1+1 power redundancy and dynamic load sharing, eliminating single points of failure for mission-critical enterprise networks.
7. High Energy Efficiency
   High-efficiency power conversion design lowers power consumption and heat generation, reducing long-term operating costs for large-scale PoE deployments.
