Configuring 16-Port and 32-Port Asynchronous Network
Modules
You can configure the asynchronous interface manually by entering Cisco IOS commands on the
command line. This method, called configuration mode, provides the greatest power and flexibility.
Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the
AutoInstall process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN
connection on both ends and the router does not have a valid configuration file stored in nonvolatile
random-access memory (NVRAM) (for instance, when you add a new interface). It can take several
minutes for the router to determine that AutoInstall is not connected to a remote Transmission
Control Protocol/Internet Protocol (TCP/IP) host.
Before you begin configuring the asynchronous interface, make sure you:
