The 1400 W DC triple-input power supply is not compatible with other power supplies used on these
Note
products, and can only be used with similar supplies. In redundant mode, the two power supplies must
have identical inputs.
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

Catalyst 4500 E-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-E requires at least 1400 W of input power. (The 1000 W AC and 1300 W AC power
supplies will fit and function in a Catalyst 4510R-E; 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-E.
When power is removed from one power supply on a Catalyst 4500 E-series switch that has two power
supplies, the redundant power feature causes the second power supply to produce full power.
