Providing Power to the Phone
The Cisco Unified IP Video Phone 7985G 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.
Note
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.
