You can connect a console directly to the RJ-45 console port or to the USB 2.0 full-speed port of
the gateway. These two ports are labeled as CONSOLE (see Figure 7 on page 11).
Figure 7: Console Ports
RJ-45 console port
USB console port
RJ-45 console port to connect the gateway to the serial port (RS-232 Port/COM port) of the PC
having console terminal session. An RS-232 serial cable with an RJ-45 connector is required.
USB Type B console port to connect the gateway to the Type A USB port of the PC having
console terminal session. A standard USB cable with Type B connector is required.
Note: Although you can connect management devices to both console ports, only one console
port can be active at a time. If you connect to both the console ports, the USB console port will be
activated.
