Cisco PWR-C45-2800ACV is a high-capacity 2800-watt AC power supply designed for the Cisco Catalyst 4500 Series modular switches, particularly larger chassis deployments such as the 4507R and 4510R.

The “ACV” (AC High Voltage) designation indicates that this PSU operates on high-voltage AC input (typically 200–240V), delivering sufficient power for PoE-heavy and high-density line card configurations.

It is built for enterprise and data center environments requiring reliable, redundant, and scalable power delivery.
