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.

Complete the following steps:

1.Conﬁgure the modem, using the parameters in Table 1-4.

Table 1-4.	External Modem Parameters

Modem Signal/Parameter		Value

Clear To Send (CTS)		On

Data Terminal Ready (DTR)		Set to answer all incoming calls.

Data Carrier Detect (DCD) or RLSD		On while carrier is present (the ARN uses DCD to
		detect modem connect and disconnect).

Data Set Ready (DSR)		On

Ready to Send (RTS)		Ignored
