The MX150 has two console ports: an RJ-45 port, and a Mini-USB port.
By default, the RJ-45 port is set as the active console port. It can display all the early boot
and low-level message output and you can access the device through this port in the
debugger prompt.
The Mini-USB port is the passive console port. You can change the status of the port to
active or passive using the
Port Type (CLI Procedure).
The Mini-USB console port uses a Mini-B plug (5-pin) connector to connect to a console
management device. The default baud rate for the console port is 9600 baud.
