list the specifications for the Catalyst 4500 series power supplies, which can
be used in any Catalyst 4500 E-series switch.
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.
