Preparing for Installation
Warning
The ports labeled "10BaseT", 100BaseTX", and "10/100" are safety extra-low
voltage (SELV) circuits. SELV circuits should only be connected to other SELV
circuits. Avoid connecting these circuits to telephone network voltage (TNV)
circuits.
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
Do not work on the system or connect or disconnect cables during periods of
lightning activity.
Warning
This equipment is not designed for making emergency telephony calls when the

services. Access to emergency services can be affected by any call-barring
function of this equipment.
Warning
If the symbol of suitability with an overlaid cross ( ) appears above a port, you
must not connect the port to a public network that follows the European Union
standards. Connecting the port to this type of public network can cause severe
injury or damage your router.
