Cisco Unified IP Phone and Telephony Networks

Type

PoE power, provided by a

switch through the Ethernet

cable attached to the phone.

External power, provided

through inline power patch

panel WS-PWR-PANEL

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.
