7.3.5 Installing the WAN Cards
After installing the proper modules on the WAN cards, insert the WAN cards into the system
chassis. Each system can have up to four WAN cards, which go into slots W1 through W4.
For a system with redundant WAN cards, always insert a WAN-R card into slot W4. If you
install the WAN-R card into any other WAN card slot, it will work as a regular WAN card (not
as a redundant card). Also make sure that the WAN-R card has the same types of modules
installed on it as the associated primary WAN cards, and that those modules are installed in
the same positions (ports 1 and 2), as shown in Figure 7-3.
