Power Supply Redundancy
Catalyst 6500 series switching modules have different power requirements. Depending upon the wattage
of the power supply, certain switch configurations might require more power than a single power supply
can provide. Although the power management feature allows you to supply power to all installed
modules with two power supplies, redundancy is not supported in this configuration. Redundant and
nonredundant power configurations are summarized in
supply configurations are summarized in
For proper load-sharing operation in a redundant power supply configuration, you must install two

modules in the chassis. If you fail to install two modules, you might receive spurious OUTPUT FAIL
indications on the power supply.
