Booting the Router for the First Time
Each time you power on the router, it goes through the following boot sequence:
The router goes through power-on self-test diagnostics to verify basic operation of the CPU, memory,
and interfaces.
1.
The system bootstrap software (boot ROM image) executes and searches for a valid Cisco IOS image
(router operating system software). The source of the Cisco IOS image (Flash memory or a Trivial File
Transfer Protocol [TFTP] server) is determined by the configuration register setting. The factory-default
setting for the configuration register is 0x2102, which indicates that the router should attempt to load a
Cisco IOS image from Flash memory.
2.
If after five attempts a valid Cisco IOS image is not found in Flash memory, the router reverts to boot
ROM mode (which is used to install or upgrade a Cisco IOS image).
3.
If a valid Cisco IOS image is found, then the router searches for a valid configuration file.4.
If a valid configuration file is not found in NVRAM, the router runs the System Configuration Dialog
so you can configure it manually. For normal router operation, there must be a valid Cisco IOS image in
Flash memory and a configuration file in NVRAM.
5.
The first time you boot your router, you will need to configure the router interfaces and then save the
configuration to a file in NVRAM. Proceed to the next section, "Configuring the Router," for configuration
instructions.
Configuring the Router
You can configure the router following one of the procedures:
Using Configuration Mode--Recommended if you are familiar with Cisco IOS commands.●
Using AutoInstall--Recommended for automatic installation if another router running Cisco IOS is
installed on the network. This configuration method must be set up by an advanced Cisco IOS user.
●
Using the Setup Facility--Recommended if you are not familiar with Cisco IOS commands.●
Proceed with the procedure that best fits the needs of your network configuration and Cisco IOS experience
level.
Note You need to obtain the correct network addresses from your system administrator or consult your
network plan to determine correct addresses before you can complete the configuration of your multiport
serial router.
