Hi,
Does Cisco support 208V AC input voltage on its 4500 switch. The 208V is deliver over 2 120V phase. I know it works but do they suuport it?
All Catalyst 4500 series switch AC-input power supplies require single-phase source AC. The source AC can be out of phase between multiple power supplies or multiple AC-power plugs on the same power supply because all AC power supply inputs are isolated. Each chassis power supply should have its own dedicated branch circuit: 15 A or 20 A for North America and circuits sized to local and national codes for International locations.
