Power Guidelines

Table 2-1

provides guidelines for powering the Cisco Unified IP Phone 6921, 6941, and 6961.

Power Outage

Your accessibility to emergency service through the phone is dependent on the phone being powered. If

there is an interruption in the power supply, Service and Emergency Calling Service dialing will not

function until power is restored. In the case of a power failure or disruption, you may need to reset or

reconfigure equipment before using the Service or Emergency Calling Service dialing.

through the Cisco Unified IP

Phone Power Injector.

The Cisco Unified IP Phone Power Injector may be used with any Cisco Unified IP Phone.

Functioning as a midspan device, the injector delivers inline power to the attached phone.

The Cisco Unified IP Phone Power Injector is connected between a switch port and the IP

Phone, and supports a maximum cable length of 100m between the unpowered switch and

the IP Phone.

PoE power—Provided by a

switch through the Ethernet

cable attached to the phone.

•

The Cisco Unified IP Phone 6921, 6941, and 6961 support IEEE 802.3af Class 2

power on signal pairs and spare pairs.

•

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 running on your switch supports your

intended phone deployment. Refer to the documentation for your switch for operating

system version information.

External power—Provided

through inline power patch

panel WS-PWR-PANEL

The inline power patch panel WS-PWR-PANEL is compatible with the Cisco Unified

IP Phone 6921, 6941, and 6961.
