Starting the ARN

This chapter describes how to start the BayStack ARN router, as follows:

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.

Bay 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.
