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.

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:
•
Connect a console to the router.
•
Power on the router.
