The NetManager Console
The console is the keyboard and monitor that you have plugged into the NetManager. During boot up messages are printed on it. If the NetManager is not connected to a network, then the console provides the only method of interacting with the server.
Physical security of the console is important as it is possible to bypass normal security checks and reset system passwords if a user has direct access to the hardware.
Under some circumstances the console can be redirected to a serial port instead of using the keyboard and monitor.
