Prerequisites for Basic Software Configuration Using the Cisco IOS CLI

Prerequisites for Basic Software Configuration Using the
Cisco IOS CLI
Follow the instructions in the quick start guide that shipped with your router to install the chassis,
connect cables, and power up the router.
Timesaver Before powering up the router, disconnect all WAN cables from the router to keep it from trying to run
the AutoInstall process. The router may try to run AutoInstall if you power it on while there is a WAN
connection on both ends and the router does not have a valid configuration file stored in 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 TCP/IP host.
Restrictions for Basic Software Configuration Using the
Cisco IOS CLI
If Cisco Router and Security Device Manager (SDM) is installed on your router, we recommend that you
use Cisco SDM instead of the Cisco IOS CLI to perform the initial software configuration. To access
SDM, see the quick start guide that shipped with your router.
