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 use RJ-45 connectors. Use caution

when connecting cables.

Using an External Power Supply

The following warnings apply when you use the external power supply with the Cisco IP Phone:

Warning

This product relies on the building's installation for short-circuit (over current)

protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC,

10A 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.

Use only a Cisco-approved power supply.
