Replacing the Console or Auxiliary Cable on an MX960 Router

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 router. If you want to connect a device to both ports, you must supply another cable.

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. Press the tab on the connector, and pull the connector straight out of the port.
3. Disconnect the cable from the console or auxiliary device.
4. Plug the RJ-45 end of the replacement serial cable into the CONSOLE or AUX port. Figure 1 shows the external device ports on the Routing Engine.
5. Plug the female DB-9 end into the console or auxiliary device's serial port.
