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.
