Cisco PWR-C45-4200AC (PWR-C45-4200ACV) Full English Description

PWR-C45-4200ACV

Product Overview

TheCisco PWR-C45-4200AC (officially PWR-C45-4200ACV)is a hot-swappable dual-input AC power supply module engineered exclusively for Cisco Catalyst 4500 E-Series chassis. It supplies power for switch mainboard operation and high-density Power over Ethernet (PoE) loads, suitable for medium-to-large enterprise campus networks deploying mass PoE terminals including IP phones, wireless access points and IP surveillance cameras.

Key Features

1. Maximum 4200W Total Power Output
   Supports three power output modes determined by AC input wiring:

• 1050W: Single low-line AC input
• 2100W: Dual low-line inputs OR single high-line AC input
• 4200W: Dual high-line AC inputs connected simultaneously
  Delivers up to 3855W dedicated PoE power under full high-line configuration.

1. Universal AC Input with Active PFC
   Auto-ranging wide AC input for global deployment, equipped with active Power Factor Correction achieving ≥99% power factor to reduce power waste and harmonic interference.
   • Low line: 85VAC ~ 132VAC
   • High line: 170VAC ~ 264VAC
   • Frequency: 50Hz / 60Hz
   • Interface: Dual IEC C19 power ports
2. Hot-Swap Support
   Enables online insertion and removal without powering off the Catalyst 4500 chassis, allowing non-stop maintenance and power unit replacement.
3. Real-Time Status Monitoring
   Front panel LED indicators display AC input status, power supply health, fan status and PoE activation status. Environmental alarm and fault data can be transmitted to the supervisor module via chassis backplane.
4. Multi-Layer Circuit Protection
   Built-in over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP) and short-circuit protection to secure both the power module and host switch hardware.
5. Power Redundancy Compatibility
   Multiple identical power supplies can be installed inside the chassis to support N+1 redundant power architecture, eliminating single-point power failure for mission-critical network environments.
