Before you begin configuring the WXC ISM 200, install the module in the chassis, as described in Installing a WXC ISM 200.
When installation is complete and the router is powered on, the operating system automatically creates two interfaces:
In both interface names, slot is the higher number of the two slots in which the WXC ISM 200 is installed. For example, for a module installed in slots 5 and 6, the interface names are wx-6/0/0 and pc-6/0/0. If you later move the module to another pair of slots, the interface names are changed, and you must configure an IP address for the new wx- interface.
