Safety
Cisco 700 Series Router Installation Guide 2-2
Before installing the router, read these warnings:
Warning
Read the installation instructions before you connect the system to its
power source.
Warning
Before working on any system, turn the power switch to off and unplug
the power cord.
Warning
Before working on equipment that is connected to power lines, remove
jewelry (including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.
Warning
The ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Do not attempt to tamper with or open any public
telephone operator (PTO)-provided equipment or connection hardware. Any hard-
wired connection (other than by a nonremovable, connect-one-time-only plug)
must be made only by PTO staff or suitably trained engineers.
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.
Warning
Ultimate disposal of this product should be handled according to all
national laws and regulations.
