Supported Power Supplies

You can select from several different power supplies to ensure that you have enough power for the
modules installed in your switch.
You should select a power supply based on the modules and the amount of PoE desired using the Cisco

The choice between 1000 AC and 1400 AC should depend on the type of line cards that the customer
plans to use in the chassis.
The Catalyst 4500 series switches support the following power supplies:
•
•
All Catalyst 4500 series switch AC-input power supplies require single-phase source AC. The source AC
Note
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 ideally have
its own dedicated branch circuit sized to local and national codes.
