Appendix B: Using the DSView Client Software Over a Modem Connection

An external modem may be attached to the DSR1021 switch. This modem may be used to access the appliance when an Ethernet connection is not available.

A modem/PPP dial-up connection must be established before the remote operation is enabled. The dial-up connection options should be set to 115200 baud, 8 bits, 1 stop bit, no parity and enabled hardware flow control. The remote operations must then be enabled within the Authentication Timeout specified in the Terminal Applications menu or the PPP link will be disconnected. See Chapter 4 for more information about setting the Authentication Timeout.

Once a modem dial-up connection is established, you select the DSView Client software window Options - Remote Operations - Enable command to establish a DSView software session with the DSR1021 switch over the modem link.

When a remote operation is enabled, the DSView Client software window will contain a topology tree with the single DSR1021 switch.

The following DSView software options are not available when using a modem connection:

•Specification of an authentication server

•Enabling of port status polling

•Displaying server views

•Global macros

•Privacy mode connections to the Video Viewer window

•Viewing connected users to a Video Viewer window

Before you begin

The following actions should be performed before using the DSView Client software over a modem connection:

•Ensure that the DSR1021 switch is configured. See Getting Started in Chapter 2 for more information.

•Ensure that DSR switch users have been added to the DSR1021 switch internal database. If the DSAuth Server is not available, the appliance database is used for appliance authentication. If neither are available, authentication cannot be performed for the DSR1021 switch, an error will display and the appliance will not be available in the DSView Client software topology tree. See Accessing the Terminal Applications Menu in Chapter 4 for more information.
