Before You Begin

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning To avoid electric shock, do not connect safety extra low voltage (SELV) circuits to telephone network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

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.
