Modem Port
The MODEM port on the Management Module can be used to attach a modem for
remote dial-in management of the BitStorm 4800. The MODEM port can also be
used to attach a terminal or PC to the Management Module using a Data
Communications Equipment (DCE) cable.
Procedure
To connect a modem to the MODEM port:
1. Determine and procure the proper DCE cable type. The MODEM port requires
a DB9 socket connector. The other connector depends on the serial port on
your modem, but normally a DB25 plug is required.
2. Connect the DB9 socket connector to the MODEM 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 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.
