A Warning On Connection Cables

The RS-232, ISDN line, and Ethernet cable, are very similar to each other. It is important that you use the correct cable for each connection; otherwise, your Prestige could be damaged.

Connecting Your Computer and Your Prestige

For the initial setup of your Prestige, you must use an RS-232 cable and communications software to configure the Prestige.

After the Prestige has been successfully installed, you can modify the configuration through a remote Telnet connection. See Chapter 13 for detailed instructions on using Telnet to configure your Prestige.

Connecting the RS-232 Cable to your Prestige

To connect the RS-232 cable, first click open the door on the right panel to reveal the port. Plug one end of the RS-232 cable (looks like a telephone jack) into the port until the retainer clicks into place. Connect the other end of the RS-232 cable to the serial port (COM1, COM2, or any other COM port) of your computer.

Connecting an ISDN Line to your Prestige

Plug one end of your ISDN phone line which is included in your package into the socket on the rear panel of the Prestige labeled ISDN and the other end into the ISDN wall jack.

∙S/T interface - This can only connect to your NT-1 (Network Termination) device.

ONOTE: DO NOT UNDER ANY CIRCUMSTANCES CONNECT DIRECTLY TO THE ISDN WALL JACK.
