To use a system console to configure and manage the Routing
Engine, connect it to the CONSOLE port on the Routing Engine.
To use a laptop, modem, or other auxiliary device, connect it to the AUX port on the Routing Engine. Both ports accept a cable with
an RJ-45 connector. One RJ-45/DB-9 cable is provided with the device.
If you want to connect a device to both ports, you must supply another
cable. For cable specifications, see Routing Engine Interface Cable and Wire Specifications.

Turn off the power to the console or auxiliary
Press the tab on the connector and pull the connector
straight out of the port.
Disconnect the cable from the console or auxiliary
Plug one end of the replacement Ethernet cable
into the CONSOLE or AUX port. Figure 50 shows the external device ports
on the Routing Engine.
Plug the female DB-9 end into the console or auxiliary
device's serial port.
