passive. Upon a network failure, the active connection becomes passive, and the passive connection
becomes active.
The Cisco 4400 Series Wireless LAN Controller can be equipped with one or two Cisco 4400 series
power supplies. When the Cisco Wireless LAN Controller is equipped with two Cisco 4400 series power
supplies, the power supplies are redundant and either power supply can continue to power the Cisco
4400 Series Wireless LAN Controller if the other power supply fails.
One Cisco 4400 series power supply is included standard with the Cisco Wireless LAN Controller, and is
installed in Slot 1 at the factory. For redundancy, a second Cisco 4400 series power supply can be
ordered from the factory and may be installed in Slot 2. The same power supply also fits in Slot 1 and
can be used to replace a failed power supply in the field.
