Connecting the MX2020 Router to a Console or Auxiliary Device

 

To use a system console to configure and manage the Routing Engine, connect it to the appropriate CONSOLE port on the CB-RE interface. To use a laptop, modem, or other auxiliary device, connect it to the AUX port on the CB-RE interface. Both ports accept a cable with an RJ-45 connector. One serial cable with an RJ-45 connector and a DB-9 connector is provided with the router. To connect a device to the CONSOLE port and another device to the AUX port, you must supply an additional cable.

Warning

The MX2020 router must be adequately grounded before powering on the console or auxiliary devices, (see MX2000 Router Grounding Specifications).

To connect a management console or auxiliary device:

  1. Turn off the power to the console or auxiliary device.
  2. Plug the RJ-45 end of the serial cable (see Figure 2) into the AUX port or CONSOLE port on the CB-RE interface. Figure 1 shows the ports. Table 1 describes the auxiliary and console ports.
  3. Plug the female DB-9 end into the device's serial port.Note

    For console devices, configure the serial port to the following values:

    • Baud rate—9600

    • Parity—N

    • Data bits—8

    • Stop bits—1

    • Flow control—none
