Chapter 3 Setting Up the Cisco IP Phone
Before You Begin
Caution Inline power circuits provide current over the cable. Use the Cisco provided cable
or a minimum 24 AWG communication cable.
The following warnings apply when you use an external power supply.
Caution Only use the proper Cisco approved external power supply. Reference the
installation manual provided with the phone.
Warning This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15 A
U.S. (240 VAC, 10 A international) is used on the phase conductors (all
current-carrying conductors).
Warning The device is designed to work with TN power systems.
Warning The plug-socket combination must be accessible at all times because it serves
as the main disconnecting device. #331
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.
