The Cisco IP Phone 8800 Series phones use the CP-PWR-CUBE-4

power supply.

Cisco IP Phones 8851, 8861, and 8865 support 802.3at PoE for

accessory use. For more information, consult your phone's data

sheet.

Cisco IP Phones 8861 and 8865 are PoE Class 4 devices and require

a switch or line card with Class 4 capabilities to support extra

features.

The switch requires a backup power supply for uninterruptible

operation of the phone. Make sure that the Cat OS or IOS version

that runs on your switch supports your intended phone deployment.

See the documentation for your switch for operating system version

information.

Cisco IP Phones 8865 support UPoE.

Guidelines

To ensure uninterruptible operation of the phone, make sure that the

switch has a backup power supply.

Make sure that the CatOS or IOS version that runs on your switch

supports your intended phone deployment. See the documentation

for your switch for operating system version information.

The midspan cable and power cube provide power to the Ethernet

cable.

When you install a phone that is powered with the midspan adapter,

connect the adapter to power before you connect the Ethernet cable

to the phone. When you remove a phone that uses the midspan

adapter, disconnect the Ethernet cable from the phone before you

remove the power from the adapter.

The power injector provides power to the Ethernet cable.

When you install a phone that is powered with the power injector,

connect the injector to power before you connect the Ethernet cable

to the phone. When you remove a phone that uses the injector,

disconnect the Ethernet cable from the phone before you remove

the power from the injector.
