Catalyst 4500 Series Power Supplies

Tables A-5through A-12list the specifications for the Catalyst 4500 series power supplies.

Note 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.

For more information about power management and planning, refer to the “Environmental Monitoring and Power Management” chapter in the Catalyst 4500 Series Switch Cisco IOS Software Configuration Guide version appropriate for your software.
