Safety

Warning Before working on a system that has a standby/on switch, turn the power to standby 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 Ultimate disposal of this product should be handled according to all national laws and regulations.

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.

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.

Figure 2-1 shows the Cisco 805 router ports that include SELV circuits. For a definition of SELV and TNV, see “Terms and Acronyms” in “About this Guide.”
