Connecting a Modem to the Console Port
To connect a modem to the CONSOLE port:
1 Determine and procure the proper DCE cable type for your modem. The
CONSOLE port requires a DB9 plug connector. The other connector
depends on the serial port on your modem, but normally a DB25 plug is
required. The cable must be an EIA-232-E crossover (null modem) cable.
2 Connect the DB9 plug connector to the CONSOLE port socket.
3 If the modem will be permanently connected, fasten the connector to the
Management Module with its captive screws. If the BitStorm 4800
Express is in a rack, dress the cable to the left and attach it to the rail with
a cable tie.
4 Connect the other end of the cable to the serial port of your modem.
