Booting the Router for the First Time
Each time you power on the router, it goes through this boot sequence:
1.
The router goes through power-on self-test diagnostics to verify
basic operation of the CPU, memory, and interfaces.
2.
The system bootstrap software (boot 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 configura-
tion register setting. The factory-default setting for the configura
tion register is 0x2102, which indicates that the router should
attempt to load a Cisco IOS image from Flash memory.
3.
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).
4.
If a valid Cisco IOS image is found, then the router searches for a
valid configuration file.
5.
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.
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,

instructions.
