Power Redundancy
All Catalyst 4500-E switches offer 1+1 power redundancy, so that in the event of a power interruption
the switch can still operate using power from another circuit. The power supplies can also run in a
combined mode so that chassis can have power from both supplies at once. You will need to use the
power redundancy-mode command to configure combined mode. Redundant mode is the default.
Catalyst 4500-E switches support power supply redundancy only between power supplies of equal
wattage and type. A mix of power supplies is not supported. The second power supply recognized is
placed into err-disable mode.
