Catalyst 4500 Power Supplies
Caution Do not mix the 1400 W DC power supply with any other power supply, even for a hot swap or other
short-term emergency. Doing so can seriously damage your switch.
The 1400W DC Input power supply may be used with the Catalyst 4500 Series AC Power Shelf.
Documentation for the Catalyst 4500 Series AC Power Shelf is at:

Note The input power is configurable in the CLI. The Cisco
IOS command is
power dc input . Configure the
switch software to match the requirements of your
switch. To learn how to calculate the DC input current
for your system, refer to the
“Calculating DC Input
Current” section on page 2-9 .
