Implementing Hardware and Software Redundancy on Modular Switches
Redundant power supply configuration

The Catalyst 6000 series of switches can be configured with dual power supplies. When dual power supplies are installed, they share the power requirements of the switch. In some cases a specific combination of modules can exceed the maximum power output of a single power supply. In this case two power supplies must be installed to provide adequate power to the switch. Care should be taken if this option is chosen as the redundancy provided by dual power supplies would be compromised.

NOTE:

It is very important to maintain power budgets, especially when using inline power modules to support IP telephony.
