The MX8400 IP Address can only be set from the Serial Port (if you don't know the current IP Address). During the life of the MX8400 the serial port speed has changed from 19200 to 115200 (8,N,!), Ensure you set the correct speed in the terminal software (recommend Putty).

To set the IP Address you have to login. Once you have a serial connection, use the following to login:
