Follow these steps designed to guide you through a quick and correct installation of your Prestige
128MH.
A Warning On Connection Cables
The SMT RS-232 cable, WAN modem 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.
Connect Your Computer and Your Prestige
Step 1.
For the initial setup and configuration of your Prestige 128MH, you must use RS-232 and
communications software.
After your Prestige has been successfully installed, you can modify the configuration through a
remote Telnet connection. See Chapter 12 - Telnet Configuration and Capabilities for detailed
instructions on using Telnet to configure your Prestige 128MH.
Note on Connecting the RS-232 Cable to your Prestige
One RJ45 to RS-232 female adapter cable is included in your package. To make a RS-232
connection, first connect the RJ45 end of the cable to the CONSOLE port on the back panel of the
Prestige. Connect the other end to the RS-232 cable attached to the serial port (COM1, COM2, or
any other COM port) of your computer.
Connect the Serial WAN Port
Step 2.
The Prestige 128MH has one serial WAN port (WAN port 1) which can be connected to a Dial-up
modem, a Leased Line modem, or ISDN TA (Terminal Adapter). The serial WAN port uses a
RJ45 connector. A cable is provided to convert RJ-45 to DB-25.
