Installing and Operating BayStack ARN Routers

Connecting a Modem

You can connect a modem to the ARN using the back-panel modem port or you
can connect a telephone line directly to an optional, back-panel V.34 modem
adapter module.
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 3 for details.
A modem provides remote access to the ARN for a system administrator. We
recommend that you connect a modem in case the ARN experiences system
problems.

Connecting to the Back-Panel Modem Port

To connect a modem to the ARN back panel, you need an AT (or Hayes)
compatible modem and the Order No. 110307 modem cable that came in the ARN
console/modem cable kit.
Note: Do not use the Order No. 110308 null modem crossover adapter in the
ARN cable kit to connect to a modem.
