Preparing to Install the Cisco Unified IP Phone on Your Network
•
•
Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows
a large number of phones to be added to an existing network where there are not enough IP addresses
for each phone.
For more information, see the documentation included with a Cisco switch. You can also access switch

Providing Power to the Cisco Unified IP Phone
The Cisco Unified IP Phone 8961, 9951, and 9971 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.
