Cisco Unified IP Phone Power
The Cisco Unified IP Phone 8961, 9951, and 9971 can be powered with external power or with Power over
Ethernet (PoE). A separate power supply provides external power. The switch can provide PoE through the
phone Ethernet cable.
When you install a phone that is powered with external power, connect the power supply to the phone
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.
