Cisco IOS CLI for Initial Configuration
The following sections describe how to perform the initial configuration using the
Cisco Internet Operating System (IOS) command line interface (CLI).
• Prerequisites for Initial Software Configuration Using the Cisco IOS CLI, page A-1
• Using the Cisco IOS CLI to Perform Initial Configuration, page A-2
Note We recommend using Cisco Configuration Professional Express web-based application to configure the
initial router settings. See Cisco Configuration Professional Express User Guide at Cisco.com for
detailed instructions,

Initial Configuration of the Wireless Access Point on Cisco 1941W Router
The embedded wireless access point (AP) runs its own version of Cisco Internet Operating System (IOS)
software. Use Cisco Configuration Professional Express to perform the initial configuration of the access
point software. For information on how to configure additional wireless parameters see the “Configuring
the Wireless Device” module in this guide.
Prerequisites for Initial Software Configuration Using the
Cisco IOS CLI
Follow the instructions in the hardware installation guide for your router to install the chassis, connect
cables, and supply power to the hardware.
Timesaver Before supplying power to 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 up 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.
