Note: you will need two separate serial cables to connect both servers, if you want to be able to connect from one to the other as needed. Connect serial port 1 on system A to serial port 2 on system B. Then connect serial port 1 on system B to serial port 2 on system A.

Then configure both systems to use serial port 1 for the serial console. And to use serial port 2 to "dial-out" to the other server.

Otherwise, using a single cable between serial port 1 on both systems, you'll have both systems outputting data to the serial port (ie the serial console is connected to serial port 1), and you won't have anything available to "dial-out" on to the other server.
