Power Outage

Power type

External power—Provided

through the Cisco Unified IP

Phone Power Injector.

PoE power—Provided by a

switch through the Ethernet

cable attached to the phone.

Power Outage

Your access to emergency service through the phone requires the phone to receive power. If an interruption

in the power supply occurs, Service and Emergency Calling Service dialing do not function until power is

restored. In the case of a power failure or disruption, you may need to reset or reconfigure equipment before

you can use the Service or Emergency Calling Service dialing.

Additional Information About Power

For related information about power, refer to the documents shown in the following table. These documents

provide information about the following topics:

• Cisco switches that work with the Cisco Unified IP Phones

• The Cisco IOS releases that support bidirectional power negotiation

• Other requirements and restrictions regarding power

Unified Communications Manager 9.0 (SCCP and SIP)

Guidelines

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 100 m between the unpowered switch and the

IP Phone.

The Cisco Unified IP Phones 7962G, 7942G, 7961G, and 7941G support

Cisco inline PoE, but the Cisco Unified IP Phones 7961G-GE, and

7941G-GE do not.

The Cisco Unified IP Phones 7962G and 7942G support IEEE 802.3af

Class 2 power on signal pairs and spare pairs. The Cisco Unified IP Phones

7961G-GE, and 7941G-GE are not compatible with Cisco switches that

are not IEEE compliant.

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.
