The Cisco 1700 router supports one or two Cisco WAN interface cards. Each card
has one or two WAN ports. This section describes the general procedure for
installing a card in the Cisco 1700 router.
For details on specific WAN interface cards, how to connect the card to the WAN
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
card(s).
This section lists safety warnings that you should be aware of before installing
WAN interface cards in the router.
Only trained and qualified personnel should be allowed to install or replace this
equipment. (To see translated versions of this warning, refer to the Regulatory
Compliance and Safety Information for the Cisco 1700 document that came with
the router.)
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. (To see translated versions of this warning, refer to the
Regulatory Compliance and Safety Information for the Cisco 1700 document that
came with the router.)
Before opening the chassis, disconnect the telephone-network cables (from the
card) to avoid contact with the telephone-network voltages. (To see translated
versions of this warning, refer to the Regulatory Compliance and Safety
Information for the Cisco 1700 document that came with the router.)
