Installing WICs and VICs
Installing WICs and VICs
The router supports one to two Cisco WICs and one to three Cisco VICs. Each
WIC has one or two WAN ports and each VIC has one or two voice ports. This
section describes the procedure for installing a WIC or a VIC in the router.
Note For details on specific WICs and VICs, how to connect a WIC to the WAN line or
VIC to the telephone and fax line, and how to configure the interface with
Cisco IOS software, refer to the Cisco WAN Interface Cards Hardware
Installation Guide that came with the cards.
Safety Information
This section lists safety warnings that you should be aware of before installing
WICs or VICs in the router. To see translated versions of these warnings, refer to
the Regulatory Compliance and Safety Information for the Cisco 1700 Routers
document that came with the router.
Warning Before working on a system that has an on/off switch, turn off the power and
unplug the power cord.

equipment.
Warning Before working on equipment that is connected to power lines, remove jewelry
