Introduction

Cisco Systems® is introducing a new, dual-input, 4200 WAC power supply designed for large scale power over Ethernet deployments. The new data and voice power supply provides two inputs for increased flexibility. Inputs can accept 110V or 220V circuits depending on total power required. Dual low-current inputs eliminate the need to rewire closets with large capacity circuits.

The dual-input 4200 WAC power supply is designed for large scale PoE deployments. By providing multiple inputs, the AC power supply allows network administrators to select one of four power modes to meet their needs. Many PoE deployments require only a fraction of the 4200W available in this supply. 12 Amp inputs mean administrators can connect the supply to standard wall outlets. The 4200W power supply can power a Catalyst 4506 chassis with copper line cards on a single 110V connection. Likewise, it is possible to deploy a fully populated Cisco Catalyst 4510R with two 110V or a single 220V circuit (Table 1). Please note, installation on an 110V circuit in North America requires the use of a special cord.
