Figure 1-20 1400 W DC Triple-Input Power Supply
Note The 1400 W DC triple-input power supply is not compatible with other power
supplies used on these products, and can only be used with similar supplies. In
redundant mode, the two power supplies must have identical inputs. You will need
to power down the switch to upgrade to or away from this power supply.
The 1400 W DC input power supply (either single or triple-input) may be used
with the Catalyst 4500 Series AC Power Shelf. Documentation for the Catalyst
4500 Series AC Power Shelf is at

ation/notes/78_15068.html
Catalyst 4500 series switches support one power supply and an optional
redundant power supply. Each AC power supply has an individual power cord and
status LEDs. Systems with redundant power supplies will share the load, with
each unit providing approximately one-half of the total load. For information
about configuring your switch for redundant and combined modes, refer to the
software configuration guide for your switch.
The Catalyst 4510R requires at least 1400 W of input power. (The 1000 W AC and
1300 W AC power supplies for the Catalyst 4500 series will fit and function in a
Catalyst 4510R; however, power management may be required in high density
configurations.) Cisco recommends the use of the 1400 W DC, 1400 W AC, and
2800 W AC power supplies for the Catalyst 4510R.
