Redundancy Feature
For redundancy, you can use the Cisco AC adapter even if you are using inline power from the Cisco Catalyst switches. The Cisco Unified IP Phone can share the power load being used from the inline power and external power source. If either the inline power or the external power goes down, the phone can switch entirely to the other power source.
To use this redundancy feature, follow these steps:
Procedure
Step 1 Set the inline power mode to auto on the Cisco Catalyst switch.
Step 2 Connect the unpowered Cisco Unified IP Phone to the network.
Step 3 Connect the external power supply to the phone after the phone powers up.
