Power Redundancy
Catalyst 6500/6000 series modules have different power requirements. Certain switch configurations can require more
power than a single power supply can provide, which depends on the wattage of the power supply. Although the power
management feature allows you to power all the installed modules with two power supplies, redundancy is not
supported in this configuration.
power than a single power supply can provide, which depends on the wattage of the power supply. Although the power
management feature allows you to power all the installed modules with two power supplies, redundancy is not
supported in this configuration.
With redundancy enabled, if you power up the system with two power supplies of unequal wattage, both power
supplies come on line with a corresponding syslog message. The message indicates that the lower-wattage power
supply will be disabled. If the active power supply fails, the lower-wattage power supply that was disabled comes on
line. If necessary, certain modules can be powered down in order to accommodate the lower-wattage power supply. For
more information on the effects of power supply configuration changes, see the
