Catalyst 4500 Series Power Supplies
Table s A-5 through A-12 list 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.
