Providing Power to the Cisco Unified IP Phone

Providing Power to the Cisco Unified IP Phone
The Cisco Unified IP Phone 6921, 6941, 6945, and 6961 can be powered with external power or with
Power over Ethernet (PoE). External power is provided through a separate power supply. PoE is
provided by a switch through the Ethernet cable attached to a phone.
When you install a phone that is powered with external power, connect the power supply to the phone
Note
and to a power outlet before you connect the Ethernet cable to the phone. When you remove a phone that
is powered with external power, disconnect the Ethernet cable from the phone before you disconnect the
power supply.
