Understanding the Startup Process

To operate, the ARN requires two files: a software image and a configuration file. Each time you start the ARN, it completes a process to load these files.

The software image contains a group of executable files that support the protocols that the network requires. The ARN uses the software image called arn.exe. The process of obtaining and using this image is called booting.

To bridge and route traffic, the ARN also needs a configuration file that is tailored to the network. A configuration file is a binary system file that contains hardware and software configuration data. The default configuration file is named config.

Nortel Networks ships the executable and default configuration files on a PCMCIA flash card, but the ARN can also obtain them over the network. Getting a file over the network is called network booting, or netbooting. Getting a file from the router file system, stored in flash memory, is local booting.
