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.
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord.
Warning
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF

or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first.
Cisco 1700 Series Routers
Grounding on a Cisco 1700 series router is done on the router chassis itself, not on the voice interface
cards. For information on chassis grounding on Cisco 1700 series routers, see the hardware installation
guide for your router.
Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers
The requirements in this section apply to only the Cisco 2600 series, Cisco 3600 series, and Cisco 3700
series routers.
The cards in this chapter are suitable for exposed plant lead connection. However, the host router chassis
must have a permanent protective earth connection before you connect a voice interface card to an
exposed plant lead. Make sure that a permanent earth connection is in place before installing the card.
If you find that a router chassis does not have an earth connection and you do not have a grounding kit,
take one of the following actions:
