Warning
Read the installation instructions before you
connect the system to its power source.
Warning
Do not work on the system or connect or
disconnect cables during periods of lightning
activity.

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

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.

The plug-socket combination must be accessible
at all times because it serves as the main
