Chapter 2 Installing the Cisco 1700 Router
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (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.)
Caution Do not connect a WAN cable to the card until you have completed the installation procedure.
Installing a WAN Interface Card
This section describes how to install WAN interface cards in the router.
Installing the Cards in Correct Sequence
The Cisco 1700 router discovers interfaces on WAN interface cards installed in the WIC0 slot before it discovers those installed in the WIC1 slot. This can affect your router configuration. This section describes how to ensure that your existing router configuration is not affected when you install WAN interface cards.
If you are installing a WAN interface card in the router for the first time, install the card in the WIC0 slot to ensure that your software configuration will not be affected if you install a second card at a later time.
If you are installing a second WAN interface card in a Cisco 1720 that has a card installed in the WIC1 slot, follow this general procedure to prevent having to reconfigure your router:
Caution Read the instructions in the following section, “Installing the Cards,” before installing the cards.
Step 1 Remove the installed card from the WIC1 slot.
Step 2 Reinstall the card (removed in Step 1) in the WIC0 slot.
Step 3 Install the new card in the WIC1 slot.
