Installing the ARN
Connecting a Console Modem
A modem provides a system administrator with remote access to the ARN. It is a good idea to connect a modem in case the ARN experiences system problems.
Note: To use the Netboot, Directed Netboot, or Local Boot software configuration options, you must connect a console the first time you power up the ARN. Refer to Chapter 2, “Starting the ARN” for details.
To use a modem connection for a management console, you can connect an external modem to the modem interface or you can connect a telephone line directly to an optional V.34 Console Modem adapter module. Both ports are on the ARN back panel.
